I actually tried two of these. The first one died almost instantly (red light on, would do nothing else and reset did not work), so was returned and this one repurchased. This dash cam ticks all the boxes, but for some reason, will not work on my motorcycle. I have a large touring bike, with a big windshield, and this is perfect for attaching to it, being able to remove it when off the bike, with the magnetic connection to the mount. HOWEVER, and it is a huge HOWEVER, for some odd reason, this refuses to work plugged in to my bike. It worked at my desk, plugged in to a USB power supply and it worked in my car, but why, oh why, did it dislike my motorcycle? The bike has three power outlets. I checked the voltage at each one and when standing, it was 12.7 V, when running, 14.5 V and when switched off, 13.9 V (gradually dropping back to 12,7 V). I tried different 5 V USB adapters (and different USB cables) and nothing. Zilch! Zip! The green light comes on, solid, but no other. Not wifi output or any other functioning.
Does anyone have any ideas why this might be? I am stumped for a reason.

But that could be pointing to the problem: perhaps your cam is drawing much more current than it should? Just a guess on my part, you seem to have tested every other aspect quite well so far and I'm baffled too
