We've had a RoadAngel Halo Go fitted with a permanently-on 12v feed - it's only a two wire connection. Does anyone know what triggers the dashcam to startup when the engine is running?
I expect the hardwire lead drops the 12v down to 5v for the usb connection into the dashcam, so not sure how it 'knows' the engine is running unless it uses one of the other contacts on the usb connector somehow.
As you might have guessed, ours isn't starting up on engine run, only on shock (either tapping the dash cam, or when you hit the first bump whilst driving - although given the state of the roads at the moment, that doesn't take long), hence the reason for wanting to know how it should work
I would have assumed it detects the increase in voltage when the engine is running, and I've checked the voltage at the fusebox where it's plugged in is just above 14v when the engine is running, but don't see how this would work anyway if it only uses the 5v usb connection at the actual dashcam
