Relay Breaks the Red(power) wire in the USB ext. cable. The software (USB Webcamera Pro) senses the break and closing of the relay as
connection of a USB Camera and switches table display to camera output. The trigger wire for the relay should be connected to the reverse light circuit of your vehicle.
If I get a warm day, I’ll get this installed and make another video.
Thanks to Craig Brugger for the idea and the USB software recomendation. https://youtu.be/yEfu4n1RAu4
