My cheap and easy dash cam, until I get the nerve to trust someone to hard wire one to the windshield that is.
Works like a charm, my cheapo action cam actually has a good dash cam mode, turns on & starts recording when you turn on the truck, stops recording and turns off when you turn off the ignition. I used a flush mounted USB adaptor inserted into the 12v outlet to power the unit.
I do unclip and hide the cam in my center console when not in use in case some thief confuses it for an actual GoPro.
