  • Why Did My SJ7 Stop Working?

    Why Did My SJ7 Stop Working?

    UPDATE MAY 23, 2017

    Yesterday I received an e-mail from SJCam with an update on this issue.  Here’s a portion of the text from that e-mail:

    Please see attached picture.
    It turns out that there was an issue with a few units during assembly.
    Your unit should have a screw instead of soldering. Anyways, the screw was touching the other highlighted part causing it to overheat.
    Instead of using a screw, we are now soldering and upgrading the assembly and QC process.
    In addition, we have upgraded the faceplate material to a more heat resistant material as well.
    These measures should ensure that what happend to your unit will never happen again. (sic)
    So it seems that SJCam has investigated the problem, discovered it’s not one of a kind and come up with a solution.  I must offer SJCam credit where it’s due.  After their initial angry response they actually settled down and took a serious look at the situation.
    SJCam said they will send me a new upgraded SJ7.  I’ll run my full battery of tests and report back to you when I’m done.

    Recently I’ve been reviewing the SJCam SJ7 Star action camera.  Part way through testing it became inoperable.  How did this happen?

    Before and after

    The photo on the right above shows how the front of my SJ7 became warped and distorted, causing the camera to be unusable.  Unlike the top, sides and bottom of the camera body, the front is made of plastic, not aluminum.

    The front of my SJ7 became deformed some time during 3 hours of use as a dash camera.  I was using it with the battery removed and powered by a USB power bank. It was mid-afternoon in Georgia, USA. Outside temperature was about 29°C (85°F) with the A/C running in my vehicle and one stop of about 30 minutes with the windows rolled up.  I was recording in 4K.

    One can only speculate as to why this happened.  Because the camera was mounted on the windshield of my vehicle the sun was shining directly on it.  Was the front of the camera unable to withstand the heat of the sun?

    Did the internal components of the SJ7 overheat, causing the front to deform?  If yes, how did the camera continue to record video without any files being corrupted and why weren’t the circuit boards inside the camera deformed?  When I removed the camera face and looked inside I could see no evidence of overheating.

    What the SJ7 looked like inside after being deformed

    In accordance with the official User’s Manual I had removed the battery before using it as a dash cam.  This is addressed on page 18 (VIDEO RECORD – Page 2) of the manual.  When I discovered the warping I immediately disconnected the camera from the USB power bank.  I’ve since confirmed with SJCam that there’s no prohibition against using a power bank with the SJ7.  Afterwards I tried to install the battery but due to deformation it no longer fit in its compartment.

    I tried connecting AC and DC adapters and the power bank again but the camera wouldn’t turn on even though Car DV mode was on. (With Car DV mode turned on, the camera should power up and begin recording as soon as a live power source is connected.)  I tried using the camera’s power button after connecting to an external power source but because the faceplate was so warped it wouldn’t work.  I now have a brick.

    In follow-up emails, SJCam strongly advised users to remove the battery from their SJ7 before using it as a dash cam.  The SJCam e-mail described it as “an additional layer of safety”.  They also said that they were looking into changing the faceplate material, improving ventilation and perhaps modifying firmware.

    So, is this a failure of the plastic material used for the camera front?  Is it a failure of the protection circuit that shuts down the camera in the event of overheating?  Is it a shortcoming in ventilation?  Is it some combination of these?

    There are tens of thousands of action cameras being used as dash cameras.  How many reports of warping and deformation have you heard of?  Personally I’ve heard of two including this one.  No doubt there are more but surely this isn’t a widespread problem, is it?

    I have four other action cameras that I’ve used as dash cams and I’ve never had a problem with them.  I’ve used them in higher temperatures for longer periods of time than the SJ7.  Indeed, I’ve been using the SJ7’s sibling SJ4000 for 21 months as a dash cam without a hitch.

    Until and unless SJCam actually implements the changes they say they’re looking into, I strongly urge anybody thinking about buying an SJ7 to reconsider their choice.  Even if I hadn’t had the deformation problem I would not have recommended the SJ7 as I make clear in my abbreviated review.

    In the comments below I would like to hear from anyone who has had a problem with their SJ7 action cam regarding deformation, warping or overheating for any reason.  I’d like a better understanding of how widespread this problem might be.  In the meantime I hope current SJ7 owners will keep a close eye on their cameras to ensure that they don’t have the same issue.

    The camera I was testing was provided by SJCam.  I was assisting to beta test their firmware and offering other suggestions about the camera, packaging, manuals and website.

    SPECIAL NOTICE

    The following article was written before my SJ7 test camera became inoperable.  After three hours of use as a dash camera, the SJ7 warped and deformed.  The review is incomplete but gives you an idea of my impressions based on testing I had completed up to the time of the problem.

    Please see my separate article Why Did My SJ7 Stop Working? for background, photos, details and other information.

    As a result of this problem I have no choice but to emphatically recommend against purchasing an SJ7.  As you’ll see below I wasn’t going to recommend it anyway.


    These days several action camera manufacturers are introducing new cameras that shoot true 4K video. Chinese action camera maker SJCam has just joined the fray with the introduction of their top-of-the-line camera, the SJ7 Star.

    The SJ7 Star was originally scheduled to be released in early 2017 but was delayed multiple times as the firmware was sorted out. My review camera originally had firmware version 1.05 but was updated to version 1.13, the latest available at the time of this review. More revisions are in the works so please come back and check this article for updates.

    There’s been lots of hubbub about the SJ7 Star. Is it warranted?

    RATINGS AND SUMMARY

    NOTE:  Ratings withheld due to problem with camera.

    HIGH POINTS

    • Records true 4K video
    • Touch screen is wonderful
    • Battery performance is good
    • SJCam customer support provides timely, understandable responses – a cut above typical Chinese action cam brands.
    • Downloadable online manual is also quite good (though not entirely current with latest firmware)

    LOW POINTS

    • Software is still being developed so there are glitches and omissions
    • Settings like Color, Scene and adjustable FOV are missing
    • EV and ISO settings don’t work
    • No digital zoom
    • No 180° image rotation
    • Gyro stabilization only works with 1080p 30/60fps
    • Double frame rate for most 60fps and all 120fps videos at night
    • FPV unavailable
    • The internal microphone is just okay and using external mics is a shot in the dark
    • iOS app doesn’t work right
    • No 1/4-inch tripod connection on camera body and the included frame-style camera mount is less convenient that a camera clip
    • Swiping and touching the touch screen menu mostly doesn’t work with the waterproof enclosure’s touch back door
    • Does anybody really need nearly two dozen resolution/frame rate combinations?

    SUMMARY

    At this time I can’t recommend the SJ7 because it feels like an incomplete product. There are still firmware problems that SJCam needs to iron out. Hopefully they’ll do so with the next iteration of firmware and apps. My test camera had firmware version 1.13 and the apps were version 5.1.4.

    There are simply too many settings that don’t work correctly or are missing. Basics such as EV and ISO don’t work and Color, Scene, adjustable field of view, digital zoom and 180° image rotation are all missing. You basically need to leave settings on Auto because you can’t reliably adjust for conditions.  Automatic frame doubling of videos at night is annoying on a top-shelf camera.  You should be able to select a lower frame rate – not frame doubling – to take over automatically or lock in daytime rates..

    RC enthusiasts will be disappointed that the SJ7 does not support FPV. Also the internal mic could do a better job and there’s no guarantee that an external mic will do any better.

    But it’s not all doom and gloom with the SJ7 because it certainly has some strengths.  It has a nice feel in hand and the aluminum camera body is visually appealing.  Be careful not to leave it in the sun too long – the metal body can feel especially hot to the touch.  The buttons feel great but who needs buttons when you have that wonderful touch screen! I can assure you, once you’ve had a touch screen camera you won’t want to go back to buttons.

    The waterproof enclosure seems well made and there again the buttons feel just right. You’ll be tempted to forego the buttons because a waterproof touch back door is included.  Unfortunately swiping and touching didn’t work with it most of the time.

    The battery performance was really quite good. You can get an hour of recording at 4K with WiFi and the screen on. Recharging time was reasonable too.

    The Android app works well but I couldn’t get the iOS app to work right. It connected easily but as soon as I snapped a photo it would get hung up. I couldn’t do anything but exit the app and start over.

    You could purchase the SJ7 now in anticipation of SJCam improving the firmware but there’s no guarantee that changes equate to improvements. If you look at our SJ6 Legend review you’ll find that the last firmware update made the image quality worse, not better.

    While not part of my ratings I’ll briefly mention the optional extras. The remote control, external battery charger, spare battery and selfie stick are all worthwhile accessories. However, the SJCam lav mic did a very poor job, actually making the audio performance worse.  Don’t bother with it.

    SPECIFICATIONS

    [go_pricing id=”sjcam_sj7star”]

    BACKGROUND

    What is true 4K video? It means that a camera shoots videos with a native resolution of 3840 x 2160 pixels and a native frame rate of not less than 23.976 frames per second. These are the formal definitions of the Consumer Technology Association and the International Telecommunications Union.  The SJ7 Star meets these definitions.

    There are many “fake 4K” cameras out there that fail these definitions. Beware of any camera under USD $150 that claims to be a true 4K camera. It’s unlikely because the cost of components prohibits a lower price (though the ThiEYE T5e action camera has recently broken through the basement). Generally you should expect to pay upwards of $200 as of the date of this review.

    With its Sony Exmor R IMX117 image sensor, Ambarella A12S75 image processor and touchscreen display the SJ7 certainly has the right hardware to justify it’s introductory price of $199.

    The SJ7 for this review was provided by SJCam at no charge. They asked me and several other people to assist in testing the camera as they developed the firmware. SJCam also provided their optional remote control, microphone, selfie stick and external battery charging cradle with spare battery at no charge. To SJCam’s credit, they paid attention to all of us who were testing the camera and corrected many problems. They even made a few changes to their packaging and manuals based on our suggestions.

    Unfortunately SJCam hasn’t gone far enough to correct their website. Their description of the SJ7 seems to be what they hope it will be, not what it actually is. Please read this review thoroughly to understand the camera’s true capabilities vs what’s on the SJCam website: they’re two different things.

    I also tested the response of SJCam’s Customer Support. They offered timely, correct and understandable responses. This is a big leap forward for a Chinese action camera manufacturer. If you need help using the SJ7, fear not: SJCam will be there.  The official downloadable User’s Manual is also pretty good – a big surprise for a Chinese action camera maker.

    SJCam’s recommendations regarding memory cards are all over the place.  The website, official User’s manual, the box and the printed manual inside it all have different recommendations.  However, SJCam sent me the page shown below from their Chinese-language website.  It depicts their recommended cards.  I used the SanDisk Extreme 64GB (first one shown) without problems.  SJCam claims you can use “select” 128GB microSDXC cards but I don’t know which ones.

    SJCam’s recommended memory cards for the SJ7 Star

    VIDEO QUALITY

    Although the firmware is still evolving, currently the SJ7 lacks some common features and some less common ones that SJCam claims are forthcoming. Firmware version 1.13 on my test camera lacks a color setting to choose color, black and white, sepia, etc. It also lacks what SJCam calls “Scene” (not sure what it is). Three features important to some people but missing on the camera are adjustable field of view, digital zoom and 180° image rotation, things you would expect on a high-end action camera. Hopefully SJCam will update the firmware soon to add these missing features. These are all missing from the Photo menu as well.

    Then there’s the problem with Exposure Value (EV) and ISO: they don’t work. I ran through all the settings on each one and ended up with most of the videos looking the same with one or two either lighter or darker. That’s not how it’s supposed to work. Photos have the same problem. SJCam says this is addressed in a forthcoming firmware release. We’ll see.

    PHOTO QUALITY

    As I mentioned in the Video Quality section above, several settings don’t work or are missing including EV, ISO, Color, Scene, digital zoom and 180° image rotation. One setting that does work well is adjustable metering. The camera will adjust to the lighting of the scene overall, center weighted or at a spot exactly at the center of the field of view.  This can be helpful in scenes where there is a substantial contrast and you want to get certain elements properly exposed.

    AUDIO QUALITY

    The SJ7 has an internal microphone but you can also connect an external mic via the mini USB port. SJCam offers its own branded mic but others can work too. That’s just as well for reasons I’ll describe further down.

    The internal mic does an okay job of recording audio but I would have expected better on SJCam’s top camera. To my ears the loudness is too low overall and the recorded pitch and timbre just don’t sound like the original source. The SJ7 has adjustable mic sensitivity settings in 10 percent increments from 50 to 100. This might be useful if you’re using an unusually sensitive external mic or if you’ll be recording where there’s lots of wind noise.

    The optional SJCam external mic does a very poor job.  It barely picks up any sound and the loudness is way too low.  Turning up the volume turns up the hiss.  Oddly, when I tried it on a different brand action camera it actually worked okay – go figure! I tested SJCam’s lav mic (their “A” mic), not the the one with the flexible neck (“B” mic).

    SJCam branded lavalier microphone

    If you want to use an external mic it’s hard to know in advance what works. I tried two others besides the SJCam mic.  The Eaton lav mic was an improvement over the SJCam’s internal mic.  All sounds seemed more accurate and the loudness was better.  My Movo GM100 lav mic didn’t work at all – it recorded nothing.  Both require mini USB adapters.

    Eaton mic left, Movo GM100 mic right

    None of the external mics, including the SJCam mic, are reflected in my audio quality ratings but the Eaton and SJCam mics do demonstrate that the SJ7’s external mic capability works.

    BATTERY AND POWER

    I got the following recording times under the most and least demanding settings.

    • 4K 30fps, screen on, WiFi on – 62min
    • 720p 30fps, screen off, WiFi off – 116 min

    Recharging time was 142min using a 2.0A adapter.

    The battery performance was really good. Getting an hour of video in 4K with the screen and WiFi on is quite a feat. You can get a maximum of almost 2 hours in 720p, screen and WiFi off. Other times will fall between these extremes and of course you’ll get more time on any setting with the screen and WiFi off. It took 142 minutes to recharge the battery – a reasonable time for an action camera.

    These were measured at an ambient temperature of about 23°C (74°F). Times might be different at other temperatures.

    The SJ7 can operate with or without a battery while connected to an AC or DC adapter or a USB power bank with a minimum 1.0 amp output.  Unfortunately SJ4000/SJ5000/M10 batteries don’t fit the SJ7.  An external charging cradle is available for SJ7 batteries.  SJCam sent me a spare battery but I haven’t seen any for sale.

    DESIGN AND BUILD QUALITY

    Camera

    The design of the SJ7 Star is a step up from the typical “matchbox” style camera. The metal camera body in the beautiful Rose Gold color (one of three available) is aesthetically appealing. The camera is a bit heavier and smaller than similar cameras and has an excellent feel in hand.

    All the seams fit very tightly on my test camera, the finish was uniform and smooth and I found almost no faults with it at all. Only using a magnifying glass (!) could I see that there were a few minor rough spots along some seams but you couldn’t see them with the naked eye and you couldn’t feel them at all.

    The buttons offer a very nice tactile sensation. The resistance feels just right and they have a nicely refined click. Even the chime and shutter sounds and startup/shutdown tunes are pleasant. The ports for cable connections and the memory card slot feel well connected – nothing flimsy about them.

    The big story besides the true 4K video is the touch screen. More and more manufacturers are offering touch screens on their high-end models and it’s easy to understand why. It makes navigating menus and settings a breeze. You swipe and touch just like your smartphone. The buttons offer full redundancy but they seem like stone age tools compared to the touch screen!

    However, it’s not all perfect. On my camera the battery compartment door wouldn’t open. After much work I finally forced it open but it’s still very difficult to slide. It is a nice door though, with a spring loaded metal hinge.

    While SJCam did include a lens cap it’s incredibly flimsy and won’t hang on. Tilt the camera face down and give it a slight bump and the cap falls off.

    Flimsy lens cap

    Protection of ports and the memory card slot is also a concern. Unlike other action cams, the openings are not indented from the surface of the camera body. It looks nice but I’m not too keen on it. If you accidentally drop the camera then you’re more likely to get dirt and debris inside the openings because they’re right on the surface. The memory card might also pop out if it takes a direct hit. Try finding a microSD card in the sand or grass!

    The chimes, lovely as they are, are so quiet as to be inaudible when there’s even a modest amount of ambient noise. The lighted shutter button is nice but all the camera’s lights are too dim outdoors. The LEDs on the back of the camera are difficult to see indoors and useless in sunlight. Light from one LED bleeds over into the other one.

    Then there’s that metal body. It’s appearance is so very pleasing at first. However, when I recorded 4K video with the camera in direct sunlight and an ambient temperature of 28°C (82°F) for 30 minutes, the camera body became too hot to touch.  This can happen with other action cameras too but with the SJ7’s aluminum body it feels especially hot to the touch.  Fortunately it never shut down and the video looked fine.

    Waterproof Enclosure

    The waterproof enclosure is well made and the camera fits snugly inside. The latch is very secure though some might find the slide lock a bit fussy. The buttons have a wonderful feel, perhaps the best of any camera I’ve used. The resistance of the springs is just right and you can feel when they reach their limit of travel on the camera body, thus offering positive feedback.

    You can even use the touch screen with the waterproof enclosure by installing the included touch back door. That protects the camera in dust, mud and rain while still letting you use the touch screen. But the touch back door can only be submerged to 3m (10ft) – good for splashing about in the pool or snorkeling.

    At greater depths up to 30m (98.4 ft)  you’ll need to use the standard waterproof door and resort to the buttons so choose as many settings as possible before you put the camera in the housing. Make sure your battery is fully charged too.  Also please see our article about waterproof enclosures.

    I couldn’t check SJCam’s claimed maximum depths but they did pass my overnight kitchen bowl test.  I submerged the enclosure in a large bowl full of tap water for 12 hours.  There were no leaks.

    Unfortunately the touch screen menu only worked occasionally with the touch back door using my fingers whether in air or water.  I couldn’t check it’s performance in cold weather or with touch screen gloves.

    Accessories

    The standard accessories included with the camera are typical of SJCam, i.e., they’re all good quality.  There aren’t as many as with some of their other models but there are enough to get started.  Anyway mounting accessories are cheap and you can get just the ones you want.  GoPro-style mounting accessories work with the SJ7.

    Standard accessories included with the SJ7 Star

    The frame mount included with the camera looks very tidy. Unfortunately the camera fits just a bit loosely inside it plus I prefer the old fashioned camera clip like the one with my SJ4000. Why? With the frame you must dismount it so as to unscrew the frame to do anything with the camera whereas with the clip you simply slide the camera out, no fuss.

    SJ7 frame mount top, SJ4000 clip mount bottom

    The frame mount also makes it a pain to invert the camera (180° image rotation isn’t a menu option) or to change the battery. If you need to attach a USB cable and the camera is in an awkward position, like mounted on your windshield as a dash cam, it’s difficult to reach up and attach the cable whereas with the clip you attach the cable to the camera while it’s in hand and then slide the camera into the clip.

    One feature missing from the SJ7 is an integrated 1/4-inch tripod mount in the camera body just like the SJ6 Legend. Alas, where SJCam giveth they now taketh away.

    Let me also mention the optional accessories provided by SJCam. They’re not part of my camera ratings but they might interest you.

    Optional accessories

    First is the remote control. You can mount it on a wrist strap or the SJCam selfie stick. After you’ve paired it with the camera for the first time you never have to do it again. You can start/stop recording, snap photos, shoot a burst of photos, turn WiFi on/off or turn the camera off. You can’t turn the camera on.

    Remote control can be mounted on the wrist strap . . .

    Because all the buttons have a flat black color and the four corner buttons are exactly the same shape, it’s difficult to figure out the right orientation for mounting . It’s easy to remove and insert the remote so switching from wrist strap to selfie stick is a snap. The camera responds almost instantly when you press a button. SJCam says the remote control is waterproof to 10 meters (about 33 feet).  I couldn’t check it at that depth but it did pass my overnight kitchen bowl test.

    Second, the selfie stick is available separately and it’s a gem. This is the best selfie stick I’ve ever used and it works with any action cam or smartphone. Despite it’s light weight the telescoping extensions are absolutely rigid metal and expand to a maximum of about 36 inches including the handle. You twist them one way to unlock them for smooth extension/retraction and twist them the other way to lock them in place.

    . . . or on the excellent selfie stick.

    The handle is a textured rubber that offers a secure, comfortable grip for most hands. It has a 1/4-inch threaded opening in the bottom so you can use it as an add-on to another extension or tripod. Unfortunately, as I’ve found with other SJCam threaded bushings, it’s too shallow and bottoms out before you can screw it all the way in. The attachment at the other end is a GoPro style mount. That could be a plus or a minus depending on your needs.

    Third is a spare battery and external dual-battery charging cradle – pretty straightforward and hard to mess up. Finally there’s the SJCam branded microphone.  The manufacturing quality looks fine but the performance is poor as discussed in Audio Quality above.

    OPERATION, MENUS AND SETTINGS

    The SJ7’s touch screen makes navigating menus a breeze. It was responsive and never surprised me with any odd behavior. I only tested it with bare fingertips in mild temperatures. I can’t say how it works when it’s cold or if you’re wearing touchscreen gloves.  The buttons offer full redundancy for navigating menus.

    Thank goodness the touchscreen works so well because there’s an abundance of video and photo settings on the SJ7, more than I personally would ever use, but professionals and serious amateurs will no doubt appreciate them. You can also select from a number of convenience features.

    In a big surprise for a Chinese action camera, the online User’s Manual does a good job of explaining the menus and showing the screens. In fact it does it so well that I’m going to skip my usual screen shots and extensive menu listings and refer you to the manual instead.

    Even with touch screen navigation and clear instructions, using the SJ7 is still frustrating because the firmware remains half-baked.  The list of problems and omissions includes the following:

    • No FPV capability
    • No adjustable FOV
    • Gyro stabilization only works in 1080p 30/60 fps
    • No 180° image rotation
    • No digital zoom
    • EV and ISO settings don’t work
    • No Color or Scene settings
    • Automatic frame doubling of 60/120fps frame rates at night – should be selectable and at half the frame rates (30/60), not frame doubling
    • Can only exit WiFi Password and WiFi SSID menus by turning off the camera
    • No webcam capability

    Some people might find these to be mere annoyances while others might view a few of them as serious shortcomings.  Perhaps most serious for some is the lack of FPV capability. According to SJCam this is a limitation of the Ambarella image processor – odd considering the Ambarella Product Brief calls their A12S a “Sports and Flying Camera Processor”.

    It’s also a big disappointment that gyro stabilization only works in 1080p 30/60 fps.

    Then there’s the inability to invert the image 180° using the menu. You can mount it upside down in the frame mount (even though it’s a pain to actually do this) so that when hanging it from an overhead threaded connection it’s right side up, but if you’re using the waterproof enclosure you’re out of luck.

    Even in first release beta firmware, EV and ISO settings should work.  The altogether missing Color, Scene and adjustable FOV settings are inexcusable: if your website claims the camera has certain settings then it should in fact have them.  That these problems still haven’t been addressed in the 13th version of the firmware is completely ridiculous.

    The HDMI-out worked fine. You can even operate the camera with HDMI-out while using the remote control and WiFi – not that you would, but you could.

    WIFI AND APP

    The Android app for the SJ7 worked well.  It reacts immediately to changes in settings: swiping through the menu and selecting a setting are instantaneous. There’s a slight delay from the time you touch the shutter button until it snaps a pic or starts recording. There’s also about 1 second of lag with the live view – not bad at all.

    On the other hand I couldn’t get the iOS app to work right.  It connected right away but as soon as I tried to snap a photo the app hung up and I could do nothing with it.  I could only exit the app and start over.  Both apps were version 5.1.4.

    NOTES

    1. The SJ7’s image sensor, image processor and other internal hardware named in this review are based on information provided by SJCam. I did not disassemble the camera to verify components.
    2. The camera was delivered to and tested in the US. I don’t know if cameras delivered to other countries will perform the same.
    3. The camera was tested with firmware version 1.13.  Further firmware updates are currently being developed by SJCam.
    4. The WiFi and app were tested using a Samsung Galaxy S4 smartphone and an Apple iPad Mini 2. The performance of the WiFi and app might be different on your devices. The Android and iOS apps are both version 5.1.4.
    5. Videos, photos and audio were evaluated using my Windows 7 computer, 1080p monitor, 1080p TV and stereo system.  Your assessment might be different using your particular systems and components.
    6. See the SJ7 website for operating system and computer hardware requirements.
    7. Because the camera was tested in the southern US I couldn’t check it’s performance in cold weather.
    8. Warning for US consumers: I strongly recommend that you use only a UL-listed adapter for charging the camera’s battery.  The SJ7 package does not include an AC adapter.
    9. You can use the US Treasury Rates of Exchange to convert US Dollars to your local currency.

    Question: Can you buy a 4K action camera for under USD $40?  Answer: Camera yes, 4K no.

    This is the XDV 4K Sports Camera. It’s sold by the Chinese online seller as the V3 4K WiFi Sport Camera. Both “XDV” and “V3” are simply convenient names for a generic action camera whose true company name is unknown. V3 is the model name of the image processor. It’s just another of the many generic Chinese action cameras sold online.

    The Elephone Explorer Pro is an action camera from the Chinese brand Elephone.  Elephone was established as a smartphone manufacturer in 2006 and later entered the action camera market.  In this article I’ll be reviewing their Explorer Pro model.  The latest edition of this model includes a 2.4GHz RF remote control (not included with my camera).  Although the normal price is about $100 you can sometimes find it on sale at a number of websites for about $80.

    With so many other action cameras available to consumers, how does one from a smartphone manufacturer measure up against the competition?  With this review I hope to answer that question.

    Note : You can buy Elephne Explorer Pro and get free 2.4GZ remote controller on this link.

    Specifications

    Elephone claims the Explorer Pro is a 4K camera but this is simply untrue.  The “4K” resolution is actually interpolated from 2880 x 2160; it’s not a native 3840 x 2160.  At least it records at a true 24 frames per second (fps) instead of the useless 10fps-15fps typical of many “4K” cameras.

    They also say it records in 2K, a generic term for a number of resolutions.  In this case it means the Explorer Pro can record 2560 x 1440 at 30fps.  It also records 1080p at 60/30fps, 720p at 120/60/30fps, WVGA at 30fps, VGA at 240/30fps and QVGA at 30fps.  The 720p at 120fps is actually 40fps at triple frame rate.  The VGA at 240fps is actually 30fps with each frame shown 8 times – octuple frame rate!

    The camera is equipped with the 12 megapixel (MP) Sony IMX117CQT image sensor while the image processor is the ubiquitous Novatek NT96660.  Naturally it also has WiFi.  The app is available for Android and iOS devices.

    An unusual feature of the Explorer Pro is the audible feedback feature, what Elephone calls “Voice Broadcast“.  The camera speaks to you (in English only) for common actions like start and stop recording and useful warnings like memory full and battery low.  Other nice features are the Underwater Mode fill-in light  (called Diving Mode in the menu) and Night Scene.  These adjust camera settings based on conditions.  However, as I’ll show you later, Night Scene made no difference at all.  I didn’t have the opportunity to test Diving Mode.

    The camera has an adjustable 170°-140°-110°-70° field of view (FOV).  It also has both gyroscopic and anti-shake image stabilization.  A separate waterproof enclosure good for a depth of 30 meters (about 99 feet) and a 1050 milliampere-hour lithium-ion battery are also included.

    The Explorer Pro has an internal microphone but doesn’t support an external one.

    Using my own calipers and scale I measured the camera as follows:

    Width x Height x Depth:

    • Camera body – 59mm x 41mm x 31mm  (2.3in x 1.6in x 1.2in)
    • Waterproof enclosure – 76mm x 76mm x 44mm  (3.0in x 3.0in x 1.8in)

    Weights:

    • Camera only without battery – 47.0g  (1.66oz)
    • Camera with battery – 64.5g  (2.27oz)
    • Waterproof enclosure plus camera and battery – 139.4g  (4.91oz)

    The Explorer Pro has a one-year warranty according to the included warranty card.  The handling of warranty claims might vary depending on your location and the seller you choose.  The camera can be purchased directly from Elephone or from a number of online sellers.

    Unusual for Chinese action camera brands, Elephone’s customer service was actually quite good.  They usually responded within a day and their answers to my questions were complete and clear.  Perhaps their background as a smartphone manufacturer has had a positive influence.

    Unboxing

    The box is an elegant and sturdy design.  There’s an inner box with the camera and accessories that slides out of the outer box like a drawer.  There’s even a drawer pull tab!

    Elephone Explorer Pro Action Camera Unbxing 3in1 photo

    The outer box has simple graphics with the logo, a photo of the camera and the model name nicely printed.  Inside the inner box are two more boxes, one with the camera visible in its waterproof enclosure and another with the accessories.  The camera box has good protective padding.

    Quite a few accessories are included.  While a USB cable is included, Elephone continues the recent trend of excluding the AC adapter.  An HDMI cable is not included.

    The User Manual is seriously lacking. Only a few of the settings and operations are explained and none of the on-screen display (OSD) icons are depicted or described.  No mention is made of the Elephone’s Voice Broadcast feature.  The User Manual also makes this odd statement: “Fall or hitting the camera will do irreparable damage to internal components.”  But this is an action camera, isn’t it?  Perhaps the camera should have been called the “Armchair Pro” instead.

    The list of included accessories is as follows:

    • Waterproof enclosure
    • 3M Adhesive Tapes
    • Cleaning cloth
    • Straps
    • Bicycle mount
    • Accessory Seat (No. 1)
    • Accessory Seat (No. 2)
    • Steel Rope
    • Ribbon
    • Fixing Base
    • USB Data Cable
    • Helmet Seats
    • Adapter
    • Adapter stand (No. 1)
    • Adapter (No. 2)
    • Adapter stand (No. 3)
    • User Manual
    • Warranty Card

    Design and Build Quality

    I must say I like the appearance of the Explorer Pro.  The brushed finished in front, the vertical band with an elongated red button for Power/Mode and the u-shaped insert for the lens are all nice touches.  The knobby texture of the top, bottom and sides makes it easy to grip.

    Unfortunately the build quality leaves something to be desired.  The front of my camera was ever so slightly bowed out along the top seam.  It clicked into place when I pressed on it, like plastic on plastic, but it popped out again a few times until it finally stayed in place.

    The bottom-mounted battery compartment door was installed the wrong way ’round but I easily reinstalled it the right way.  Even correctly positioned it’s not especially easy to open.  You need to be sure it goes back the right way because it’s not attached to the camera and if it pops open or you lose it, the battery falls out.

    Elephone Explorer Pro Action Camera Top and Bottom

    There’s no dust cover over the ports and memory card slot on the side.  The outermost convex surface of the lens extends just beyond the ring that surrounds it.  The lens can get dirty and scratched and Elephone doesn’t include a lens cap among the accessories.

    The Explorer Pro is a four-button design.  It has one button in front, one on top and two on the side.  The side buttons are used to navigate menus and activate the WiFi.

    Elephone Explorer Pro Action Camera Side Buttons and Side Ports

    The buttons are a bit stiff but that means you’re less likely to press them in accidentally.  They have a definite but unrefined click.   The power turns on with a single press-and-release of the button rather than a press-and-hold.  That makes it too easy to inadvertently turn on the camera.

    The camera has a built-in microphone and speaker.  Don’t expect much from the speaker.  It’s rather loud and tinny but at least it gives you some idea of the recorded audio.

    Although the camera body doesn’t have a threaded opening for tripod mounting, the accessories include a clever camera clip that has 1/4″-20 connections top and bottom.  That way you can mount the camera hanging down without the image being inverted.  Unfortunately the clip blocks your view of the LED’s on the back of the camera.

    The waterproof enclosure seems reasonably well constructed but the camera sits inside it a little bit loosely.  The latch closure has a pretty good feel but it doesn’t snap as tightly into place as some cameras.  The advantage to the hard click of the buttons on the camera is that they turn out to be just right when using the waterproof enclosure.  The feel of pressing the housing buttons combined with a muted click is very nice.

    There’s no indication of the FOV setting nor is there an icon for gyro stabilization in Record mode.  The battery status icon is divided into rather large segments so you don’t realize you’re very close to the end until you’re already there, although the Voice Broadcast warning is helpful.

    In Record mode press the OK button to begin recording videos, press again to stop.  If you press the Mode button while recording video the camera takes a photo and the Camera mode icon briefly flashes on the OSD.

    In Camera mode press the OK button to shoot a photo.  Depending on the settings there could be a burst of photos or a delay with a beep sound counting down each second.

    To playback video go to Playback mode and press the OK button.  Press it again to pause or press the Mode button to stop.  When stopped press the Down button to advance to the next photo/video and the Up button to go back one video/photo.

    During video playback press the Down button to fast forward 2X, again for 4X, again for 8X.  While fast forwarding press Up button to reduce playback speed.  During playback press the Up button to rewind 2X, 4X or 8X and press the Down button to reduce rewind speed.

    I used the camera to record a contractor replacing the roof on my house.  Connected to a USB power bank, it recorded continuously for about 7 hours in 1080p 60fps with WiFi and display off.  The ambient temperature peaked  at 33°C (92°F).  Although the camera was hot by the end of the day it didn’t overheat and recorded the entire 7 hours without incident.

    The 2-inch display on the Elephone is bright and crisp.  The colors are true-to-life and details can be seen quite clearly.  Playing back videos and viewing photos on the camera display works well.  The icons and OSD data are easy to see and the Setup Menu is easy to read.

    Playing back videos on my 1080p TV directly from the camera via the HDMI connection worked well for videos at all resolutions and frame rates.  Playback includes audio.  Photos looked good too.  All camera functions remain available while connected – you can change settings and shoot videos and photos just like normal.  There’s essentially no lag between the camera and TV.  The camera automatically recognizes the HDMI connection.

    A useful feature missing from the Elephone is one-button toggle for gyro stabilization.  Gyro stabilization is intended for recording videos.  When shooting photos it can cause them to be blurry.  If you want to alternate between videos and photos it would be best to switch between gyro on and off but with the Explorer Pro you need to enter the Setup Menu.  A simple one-button toggle would make things much easier.  And because there’s no icon in Record mode to show when gyro stabilization is on you’ll need to remember your setting.

    On the other hand there is a one-button toggle for audio recording.  Simply press the down button on the side to turn audio recording on or off.

    The Elephone Explorer Pro also lacks adjustable metering.  Metering is the way the camera reads the brightness of the entire scene, just the center or something in between.  Adjustable metering can make a difference when you’re shooting a scene having high contrast between the brightest and darkest parts of the scene.

    Lights

    • Solid blue light – camera on
    • Flashing blue light – recording video
    • Solid red light – battery charging
    • Flashing amber light – WiFi on but not connected
    • Solid amber light – WiFi on and connected

    Beeps (if turned on) and sounds

    • Single beep – when you scroll through menu selections or change a setting; when you choose a file in Playback mode
    • Shutter sound – when you snap a photo
    • Chirp – when you turn the camera on or off
    • Voice Broadcast – “video start”, “video stop”, “low power” and memory full

    Video and Photo Settings in Common

    The following describes various settings that affect both videos and photos.  Only photos are shown for clarity.

    White Balance allows you to adjust the color temperature to match ambient conditions.  The settings include Auto, Cloudy, Daylight, Fluorescent and Tungsten.  Auto looks best outdoors on this sunny day.

    elephone-explorer-pro-white-balance

    By changing the ISO setting you can adjust the image sensor’s sensitivity to light.  The settings include (below, clockwise from top left) Auto and ISO 100, 200 and 400.

    elephone-explorer-pro-action-iso

    You’ll notice they all look the same.  That’s because the camera automatically reduced the exposure time in concert with the change in ISO value – doubling the ISO halved the exposure time.  Thus changing The ISO setting but leaving the Exposure Value on Auto doesn’t do you much good.

    You can also adjust the Exposure Value (EV).  This changes the amount of time an image is exposed to the sensor.  The following shows how the Elephone Explorer Pro does a good job of changing the EV in the normal 1/3 increments from -2 to +2.  Each step change is subtle but noticeable just as it should be.

    elephone-expolorer-pro-exposure

    You can adjust the color effect you want including Color, Black & White or Sepia.

    WDR (wide dynamic range) can be turned on or off.  Normally turning WDR on improves the colors in your videos and photos.  I didn’t notice any difference.  See for yourself in the following two photos.

    elephone-expolorer-pro-wdr

    You can set Sharpness to High, Normal or Medium.  I could only notice a difference when an image was substantially zoomed: the edges looked rather poor but in different ways depending on the setting.  Under normal circumstances and reasonable magnifications you probably won’t notice any difference.  I suggest you leave the setting at Medium because adjustments to sharpness are best done with your editing software.

    Video Quality

    As I mentioned earlier, all the Elephone’s video resolutions and frame rates are true to their settings except 4K is interpolated and VGA at 240fps is actually 30fps at 8X frame rate.  While  WVGA is normally 768 x 480, on the Elephone it’s 848 x 480. 

    For videos recorded at night with all setting on default or with Night Scene turned on, 720p at 120fps is actually 40fps with tripled frame rate.  VGA still records at 30 fps and plays back at octupled frame rate while 4K is still 24fps.  Frame rates at all other resolutions are reduced to 30fps, typical for action cameras recording at night.

    I thought the best quality videos were achieved recording in 2.5K day or night.  This isn’t surprising considering this is the highest resolution without interpolation.

    The field of view (FOV) is adjustable to four different settings.  As you can see in these frame captures, the difference between each setting was noticeable. (Below, clockwise from top left,  70°, 110°, 140° or 170°)

    elephone-explorer-fov-video

    When used as a dash cam, the camera’s gyro stabilization usually does a very good job of smoothing out large motions, making the video look smooth even when the road is not.  (See Dash Camera section below.)  However, when I was holding the camera with a hand grip and walking along the sidewalk the camera picked up every single motion, making the video look nervous.  Admittedly I was walking but even when I stopped and held the camera steady it still picked up even the tiniest twitch.

    You’ll find two unedited videos downloadable at this link.   The river video was recorded in 2.5K at 30fps with settings on default.  You’ll hear the Voice Broadcast say “Video Start” and “Low Power” (this can be turned off).  The other video was recorded at night at 1080p 30fps with settings on default.

    Except for the gyro problem, videos at night looked okay in 4K, 2.5K and 1080P.  At 720P 120fps the video had a lot of noise unless the scene was well lit.

    Dash Camera

    The Elephone Explorer Pro works okay as a dash camera, just don’t expect too much.   When CAR ACC is turned on with the camera connected to a 12V power outlet it powers up and automatically begins recording when you start your vehicle.  It shuts off automatically when you turn off your vehicle.

    The following is a frame capture in a parking lot with my vehicle barely moving.  You can see the closest license plate clearly but just two spaces further down the plate is completely obscure.  The inset photos were zoomed 400%, 500% and 600%.

    It does a nice job if you want a general record of a road trip.  However, at the end of a six-hour drive the gyro stabilization exhibited a strange jumping phenomenon.  Here are two videos showing a short trip to my post office (good) and the end of the six-hour drive (bad).

    Here are three sets of videos showing a residential street, a road through a shopping district and a narrow country lane.  In each you can compare the camera’s performance side-by-side when recording during the day with all settings on Default, at night with all settings on Default and at night with Night Scene turned on.

    The daytime videos were recorded at 1080p 60fps.  As with all action cameras, the frame rate at night dropped to 30fps.  However, as I discovered after recording these videos, with the Elephone you’ll have better quality with the resolution set at 2.5K

    The following video demonstrates the camera’s performance in a demanding situation where conditions quickly change from bright to dark to bright again passing through tunnels.  The camera quickly adjusted to conditions, though as it approached the light at the end of a dark tunnel the view was briefly washed out.  Settings were on default.

    Photo Quality

    Because the Elephone Explorer Pro has a 12MP sensor, and the full dimensions of the sensor aren’t used from edge to edge, photos above 10MP are interpolated.  Therefore you don’t really gain anything by choosing 12MP, 16MP or 20MP image sizes.

    Annoyingly, even when you turn off the date stamp it still appears on photos.  There’s no such problem with videos.

    The FOV for photos has four settings just like videos.  However, I could detect no difference between the 140° and 170° settings.  I can’t say for sure but I’m speculating that 170° isn’t available due to photos having a somewhat narrower aspect ratio of 4:3 as compared to 16:9 for videos.  (Below, clockwise from top left, 70°, 110°, 140°, 170°)

    elephone-explorer-fov-photo

    Anti-shake did a good job of eliminating any blurriness in photos I took while holding the camera by hand.  If I was reasonably steady then it was no different than using a tripod with anti-shake turned off.

    The two photos downloadable in this link are original unedited photos.  They give you an idea of the good quality daytime photos the Elephone shoots. The building was photographed at 2X zoom.

    Audio Quality

    The Elephone’s audio quality is pretty good.  It’s sensitive enough to pick up average conversations at a modest distance but when recording music the sound seems a bit flat and colorless.  The volume is plenty loud, perhaps too loud.

    Battery and Power

    Here is a sample of various settings and how long the battery lasted on the Elephone Explorer Pro.  If you’re using a 32GB or larger memory card the battery will always run out before the memory fills up.  In all cases WiFi was off.

    • UHD P24 (4K, 24fps), Quality Fine, display on, gyro on:  59 minutes
    • QHD P30 (2K, 30fps), Quality Fine, display off, gyro off:  78 minutes
    • FHD P60 (1920 x 1080, 60fps), Quality Fine, display on, gyro on:  42 minutes
    • FHD P30 (1920 x 1080, 30fps), Quality Normal, display off, gyro on:  97 minutes
    • HD P120 (1280 x 720, 120fps), Quality Normal, display on, gyro off:  73 minutes
    • VGA P240 (640 x 480, 240fps), Quality Fine, display off, gyro on:  111 minutes
    • QVGA P30 (320 x 240, 30fps), Quality Economy, display off, gyro off:  149 minutes

    These recording times could be better, especially because turning on the WiFi would make them shorter still.  Spare batteries and a charger or a USB power bank might be necessities for you.  I’ve seen Elephone spare batteries for sale but not an external charging dock.

    However, SJCam SJ4000 batteries are identical and work fine in the Elephone, plus the SJCam charging dock works with either brand battery.  SJCam products are inexpensive and widely available.  Two spare batteries and an external dual-battery charging dock are often discounted on websites like to less than $10.  I decided to try an SJCam battery in the Elephone to see if it made any difference.  It did, but it was actually a tiny bit worse:

    • FHD P60 (1920 x 1080, 60fps), Quality Fine, display on, gyro on:  40 minutes (with SJCam battery)

    It took about 2 hours to recharge the Elephone battery using a 2.0 amp AC adapter.  That’s pretty good by action camera standards.  Your recharging times might be different if your adapter has a different output.

    The Elephone Explorer Pro can work without a battery when connected to AC or 12V DC adapters.  It also works with a USB power bank with or without the battery installed.

    Charging the Elephone’s battery (or using a USB power bank) while the camera is turned on causes it to get quite hot.  Hottest of all was the glass lens – you’ll get a minor burn if you touch it.  If the camera is off while charging then it just gets warm.

    You’ll need to reset the date and time whenever you change the battery.  Surprisingly other settings are retained rather than reverting to default.  The camera date and time will reset to current when you connect with your smart device via WiFi.  Also keep in mind this hint: Leave the battery tab sticking out when you close the battery compartment door.  It makes it easier to pop the door open again.

    Menu and Settings

    The Elephone Explorer Pro has a 10-page Setup Menu with 4 selections on each page.  Once you’re in the menu you can start at Page 10 by using the up button to go backward through the pages so you’ll never need to scroll through more than 5 pages.  Default settings are noted with an asterisk (*).

    WiFi and App

    I had no problems downloading the app to my Android smartphone.  I couldn’t find an iOS app in the Apple Store but I easily installed it on my iPad Mini by scanning the QR code on the Elephone website.

    WiFi can be turned on or off in the camera’s Setup Menu.  It can also be toggled on or off by pressing the Up button on the side of the camera but only in Record mode.

    The camera I received had the original version of the firmware.  With that version the WiFi and app were so unstable I wasn’t able to test them.  After installing the firmware update things improved, at least with my Android smartphone.  You can check if you have the latest version of the app (20160408 V1.0) but by the time you read this review it’s likely that any camera you buy will have the latest firmware.  If not you can contact Elephone Customer Service to get the latest version.  Follow these steps to install it:

    • Transfer any photo or video files you want to save to your computer and format the memory card in the camera.
    • Remove the memory card and download the firmware to the card using a card reader.
    • Reinstall the memory card.
    • Remove the battery from the camera.
    • Connect the camera to your computer via USB.  (I only tried this with a Windows 7 computer.  I don’t know how it will work on other machines.)
    • When the camera turns on by itself the firmware is installed.  This might take a minute or so.
    • Disconnect the camera from your computer and reinstall the battery.
    • Format the memory card in the camera.

    Screen shots of my phone and  iPad after the update are shown below.

    elephone-explorer-pro-app-android-and-ios-preview

    The camera required three or four tries to connect to my iPad whereas it connected to my Android phone on the first or second try.  There was only about 1 second of lag when viewing shots on my phone.  With my iPad it took some time before the app would engage, frequently it would disconnect (but then automatically reconnect) and there was quite a bit of lag.  On my phone there was some delay between the time I pressed the button to start/stop recording or snap a photo and the time the camera reacted.  It was much worse with the iPad.

    If you want to you can use the app while the camera is connected to your TV via HDMI.  However, when I did so I got a “Slow Card” message on the OSD.  I’m not sure why or what it means.  It had no effect on the video quality.

    When WiFi is connected all controls at the camera are disabled except start/stop recording.  Many settings that are adjustable on the camera can’t be adjusted using the app.  You should set these at the camera before connecting to your mobile device.  The more important ones are listed below.

    • Gyroscope
    • Night Scene
    • Quality
    • Sharpness
    • White Balance
    • Color
    • ISO
    • All photo settings except image size

    APP Menu

    The menus on the Andriod and iOS app are the same (though the misspellings vary!) and the Android app adds a “wi-fi” selection (Why?).  A screen shot of each app is shown below.  I’ve used the Android app for the descriptions.

    Summary

    High Points

    • Videos and photos usually look good (depending on conditions and camera settings)
    • The many menu settings work well to adjust for conditions or achieve desired effects
    • WiFi and app work okay on Android devices
    • Voice Broadcast is a nice feature
    • Plenty of accessories including a remote control (not tested)
    • Unusually good customer service for a Chinese action camera brand

    Low Points

    • 4K video is achieved by interpolation, not native resolution
    • Some frame rates are doubled, tripled or even octupled
    • Difficulty handling light and dark areas combined in the same scene
    • Gyro stabilization did a good job in some conditions but not others
    • The battery runs out of power rather quickly depending on the camera settings
    • Wi-Fi and app with with iOS devices is unstable

    The Elephone Explorer Pro’s normal price is a reasonable $100 but when it’s on sale for $80 (as is often the case) it’s quite a bargain.  It doesn’t break any new ground: It’s mostly competent with a few high and low points.

    Some of the higher frame rates are false and it only records interpolated 4K video, not native.  Like most action cams, images in the dark leave something to be desired, even when the camera’s mysterious Night Scene is turned on, but in daylight it records very good video.  QHD (2.5K resolution) seems to give the best results.  The gyro stabilization could do a better job. Daylight photos look good.  Unfortunately WiFi with the iOS app is unstable.

    While videos and photos are average or better, what makes the Explorer Pro a good camera is it’s everyday ease of use.  The menu is easy to navigate, it has a full complement of menu selections to play with, the display is bright and crisp, and it comes with a good selection of accessories including a remote control.  The Voice Broadcast feature is useful and fun – there’s nothing like having a camera that talks to you!  The Android app works well.  And almost any SJCam SJ4000 accessory, including batteries, will work with the Elephone.

    Best of all for beginners, Elephone’s customer service is actually good – an amazing feat for a Chinese action camera manufacturer.  You can thank the company’s roots in the smartphone market for that.  It’s a more than decent action camera that won’t break the bank.  If you’re using it with an Android device I can definitely recommend the Elephone Explorer Pro.


    Notes

    1. The image sensor, image processor and other internal hardware mentioned in this review are based on Elephone’s statements.  The camera was not disassembled to verify components.
    2. The camera was delivered to and tested in the US.  I don’t know if cameras delivered to other countries will perform the same.
    3. The camera was tested with firmware version 20160408 V1.0.
    4. I used a 64GB Samsung Evo microSDXC memory card, class UHS-1.  Elephone makes no recommendation about the speed class but you should always use a good quality, name brand memory card with a speed class of 10 or faster.  Off brand or lower speed memory cards are likely to cause problems.
    5. The WiFi and app were tested using a Samsung Galaxy S4 Android smartphone and an Apple iPad Mini 2.  Other mobile devices might perform differently.
    6. The HDMI output was tested on a Panasonic 42-inch 1080p LCD HDTV.  HDMI output might look different on your TV.
    7. Photo and video files were downloaded to a Toshiba laptop with Windows 7 operating system.  Viewing videos and photos to assess quality was done using a Samsung 22-inch 1080p LED monitor/TV.    Photos and videos might look different on your monitor.
    8. Videos were played back through my home theater system to evaluate audio quality.  Audio might sound different on your system.
    9. Elephone makes no mention of any computer hardware or software requirements to play back videos recorded by the camera.  You’ll need the right software to play back 2.5K and 4K video recordings, at least on a Windows 7 machine.  I installed the Media Player Classic – Home Cinema (MPC-HC) program on my computer in order to view them.
    10. Because the camera was tested in the southern US I couldn’t check its performance in cold weather.  I also didn’t have the opportunity to verify that the waterproof enclosure is good to a depth of 30m (about 98ft) or to check the Diving Mode underwater fill-in light feature.  (It’s not an actual light on the camera, just an adjustment of settings.)
    11. Note for US consumers: There’s no indication on the Elephone website or in the User Manual that the camera complies with US Federal Communications Commission (FCC) requirements for WiFi operation, though the outer box does carry the FCC logo.  The camera itself lacks the required FCC labeling.

    UPDATE – January 15, 2017

    After publishing this review I found out there was a later version of firmware available.  I found nothing about it on the Elephone website so I e-mailed their customer service to ask about it.  Here is their reply:

    “We have no new firmware, different batch have different firmware. they are not compatible.”

    In other words, you’re stuck with the firmware you’ve got (except very early cameras like mine did have one update early on).  Therefore I can’t recommend Elephone Explorer Pro cameras that have firmware versions other than the one I reviewed because I don’t know how they actually perform.  In my review you should disregard the entire section about updating the firmware unless you have an original version and haven’t installed the early update.  My review camera was tested with firmware version 20160408 V1.0 and that is the only version I can recommend.

  • Accessories Review: The Movo GM100 Lavalier Microphone

    Accessories Review: The Movo GM100 Lavalier Microphone

    It’s well known among enthusiasts that action cameras aren’t known for recording great audio.  In an effort to fix this problem some cameras are equipped to handle an external microphone.  Here I test one, the Movo GM100 lavalier microphone.

    movo-gm100-lavalier-microphone-review

    A lavalier microphone, usually abbreviated as lav mic, is a small microphone that you clip onto the collar or lapel of your shirt or dress.  Typically this is done by way of a small alligator clip like the Movo’s.  The GM100 is an omnidirectional microphone, meaning it should pick up sounds equally well in all directions.

    microphone-movo-gm100-lavalier

    Action cams like GoPro, the new SJCam SJ6 and the Dazzne P2 Plus I used for this test don’t have the usual 3.5mm port for a microphone mini plug.  Rather the microphone is connected via their mini USB port with a microphone hard wired to a mini USB plug or via a mini USB x 3.5mm adapter plus a microphone with a standard 3.5mm plug.  The latter is the route chosen by Movo for the GM100 lav mic.

    adapter-two-pieces-all-together-cammera-connection

    Adapters are also available in a right-angle configuration instead of a short cable.  Either way, the advantage to having a separate mic and adapter is that you can use the mic alone with other devices.  That’s what I did while testing the Movo.  I used both my Dazzne camera and an old RCA mono voice recorder.

    test-devices

    So does the Movo make these devices sound better?  It seems like a bit of a mixed bag. The following video was made using the Dazzne P2+ camera without and with the Movo mic.  I left the lens cap on and added the graphic equalizer to show you the improved audio performance.

    Both parts of the video were boosted the same amount just to make the first part with the Dazzne’s P2+ internal mic audible.  That meant the second part was much louder owing to the improvement with the Movo mic.  Because it was boosted so much you hear more hiss.  It’s impossible to say if that’s due to the Dazzne or the Movo.  The music was more than comfortably loud in the room where it was recorded.

    The following video was made at a river dam.  It’s a nice steady sound that in person has some subtlety you just can’t hear electronically.  Still, give it a listen.

    In this case the Movo mic sounds worse than the Dazzne’s internal mic.  It sounds hollowed out and the loudness is actually decreased.  Again both parts were boosted the same amount for a direct comparison.

    I also tested an old digital voice recorder without and with the Movo GM100.  In that case the recording sounded somewhat better with the Movo mic.

    What about other uses such as an external microphone for smartphones and other mobile devices?  Unfortunately the Movo GM100 can’t be used with them.  One way to describe these types of audio connections is by the abbreviations TS, TRS, TRRS, and TRRRS,  designating tip-ring-sleeve connections.  In the photo below the Movo’s TRS plug is shown on top.  A TRRS plug from an Eaton mic is shown on the bottom.  Notice the two rings versus three rings.  (The number of “R’s” doesn’t correspond to the actual number of rings.)

    trs-vs-trrs

    The GM100 can’t be used with a smartphone because it doesn’t have a TRRS connector.  Similarly, a mic with a TRRS plug can’t be used with the typical mini USB x 3.5mm adapter including the Movo’s.  However, you can buy separate TRS x TRRS adapters and some mics have a switch that allows you to use them as either one.

    The Movo GM100 seems well made for it’s price.  There was no wiggle in the connections and the alligator clip was sturdy without being too hard to squeeze open.  The cable’s about 48-inches (122cm) long.  Two minor complaints: The wind protector doesn’t fit very snugly over the bare microphone; and while the Movo is packaged neatly, it doesn’t include a small carrying case or bag.

    gm100-gopro-mic

    The GM100 is available from a number of online retailers.  I bought mine from Amazon for US $14.95.  It’s also available on Amazon UK, Germany and Italy but not on Amazon Australia or The Netherlands.  It can also be purchased directly from Movo or on eBay.

    I can’t recommend the Movo GM100 because it doesn’t offer unequivocal improvements in audio recording.  Granted, some of the problem might be due to the poor quality of the Dazzne’s audio circuitry but in the music recording the Movo just made things louder, not better.  By contrast it actually decreased the loudness of the water falling over the dam.  Yes, it’s cheap, but there’s no point if it doesn’t improve the sound.  Unfortunately the Movo doesn’t.

  • Holiday Gift Ideas II: The Somita ST-3540 62-inch Tripod

    Holiday Gift Ideas II: The Somita ST-3540 62-inch Tripod

    Is it strange to see a review of a tripod on an action camera website?  After all, you don’t mount a tripod on your helmet or use one when you’re diving (or do you?!).  But action cameras can be used in all sorts of ways where it’s not the camera that’s moving but everybody and everything around it.  They have many uses at work, home, your children’s school and many social occasions.  In these cases a tripod can be your best friend for a nice, steady video that captures all the fun and action.

    the-somita-st-3540-62-inch-tripod

    The Somita ST-3540 is a wonderful, inexpensive tripod for your action camera and is a really good starter tripod generally for point-and-shoot and other lightweight cameras and accessories up to 6.5lbs (3kg).  It has all the adjustments and features of more expensive tripods but in a lighter, cheaper version.

    The three-way pan and tilt head has independent locks for each adjustment.  The quick-release mounting plate can also be tilted 90° to convert instantly to portrait orientation.

    somita-st-3540-62-inch-tripod-review

    The three-section telescoping legs use simple flip locks to secure the sections.  They have sturdy rubber feet with a ball-and-socket design to provide stable footing on all surfaces.  There’s a bullseye level on top of the legs and a second level on the head.

    somita-st-3540-62-inch-tripod-parts

    It has a telescoping center post with crank and locknut and a weight hook below that.  There’s also a convenient handle on the center tube.

    somita-st-3540-62-inch-tripod-3

    So why is this gem so cheap?  Because it’s . . . well, cheap.  Other than the legs, center tube and handle for tilt the entire tripod is plastic.  Don’t get me wrong: it’s all well made and the plastic doesn’t look or feel cheap.  But plastic is plastic.  For comparison here are photos of my father’s 80-plus-year-old tripod with it’s metal head.

    old-antic-photography-tripod

    Yes, it’s less versatile than the Somita’s but it’s super smooth to operate.  By comparison the Somita can be a bit sticky if you’re trying to make small adjustments or pan or tilt slowly.  That’s due to the friction of plastic on plastic.  It’s worse with my action cameras but less bad with my point-and-shoot, maybe because of the slight additional weight.

    However, the fact is that most of the time it’s not an issue.  Generally when I’m using the Somita things are moving faster than the “sticky speed” of the tripod head or else it’s stationary.  The knobs and handles themselves operate smoothly and the legs extend and retract smoothly as well.

    After a year of use and a few clumsy mishaps where I kicked or tripped on the legs it still works beautifully.  It even comes with a nice zippered carrying bag with strap.  One niggle: the strap is too short too sling over your shoulder and it’s really not convenient as a handle.

    somita-st-3540-62-inch-tripod-box-an-carrying-bag

    Somita makes a full range of tripods and the 62-inch (157cm) ST3540 has a sister 68-inch (173cm) ST3560.  I don’t like tripods shorter than 5ft (152cm) and I’m only 5′-8″ (173cm).  If you’re taller you should consider the 3560 instead.  Either way the Somita is a bargain.  I bought mine a year ago on Amazon for $25 – very good for a tripod of that size.  However, as of the date of this review the 62-inch ST3540 is selling on Amazon for an incredible $12.95 – a truly outstanding price.  Even the 68-inch ST3560 is only $15.95.

    At the normal $25 price I would recommend the Somita ST3540 to any action cam enthusiast or budding photographer.  At $13 to $16 I recommend you go online and order either size now from Amazon before the prices go up again.  This is a delightful holiday gift that should fit into most people’s budget.  While you’re at it order one for yourself!

    Happy Holidays from all of us at Pevly! 🙂

    UPDATE: 9 March 2017

    I mentioned in the review that the Somita tripod can be a bit “sticky” when panning or tilting due to the friction of plastic on plastic.  The simplest solution to cure this is lubrication, but you must be careful to use only a compatible lubricant.

    Petroleum oil can cause deterioration of plastic so I don’t recommend any such product.  It’s best to use mineral oil or silicone lubricant.  Both are compatible with almost any type of plastic.  If you want some technical information but in mostly layman’s terms the newsletter Machine Design has an article about lubricating plastic gears that is nonetheless applicable in our case as well.

    I bought some silicone lubricant and tried it on my Somita tripod and it made a big difference.  Now the tripod doesn’t stick at all when panning or tilting.  The tripod head moves completely smoothly even when adjusting in small increments or following slow-moving action.

    You’ll need to look closely at the head to see where to apply the lubricant for the panning and tilting adjustments because they’re on different axes but once you find them they’re readily apparent.  I applied a drop of oil at each location where there was an interface between a moving and a non-moving surface and that’s all it took.  Silicone spray lubricant is available too.  Be careful not to stain your clothes or floor and wipe off any excess.

    So try a bit of mineral oil or silicone lubricant if you find your Somita tripod is sticky.  I think you’ll be pleased with the results.
