Hi guys,
Would it be possible to trigger rear view camera not by GPIO but by detecting the presence of the video signal?
Currently I'm using an analog camera connected to a stand alone analog display. The camera gets powered when the car is put in reverse and the monitor turns on when it detects the signal from the camera.
The idea is to avoid running additional wires along the car and also an additional relay for GPIO triggering.
Thanks!
