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 GearBest 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.
