I have a Viofo A119S hard wired. There is an on/off button that isn't too difficult to push, though I never turn it off, especially when driving. I got the camera to capture evidence in case an idiot causes an accident...
It will record forever, once the memory chip if full, it starts overwriting the oldest video segments. How long it records depends on the size of the memory card, what resolution you select, how many frames per second you capture. With that said, I have mine set to max on everything. My 126GB card will hold about 6 hours of video. On some trips, I will copy the video to enable future viewing of nice scenery, etc.
