I’m going to try my best to keep electrical power consumption to a minimum on this bus. Backup cameras have wireless options and other add-ons that I decided I didn’t need. I need to see what’s 30 feet behind me, but that’s about it. I chose the wired option so I wouldn’t have to splice into another DC circuit to power the camera. This meant running wire from the front to the back. Luckily, my bus is stripped down to the studs right now, so that’s an easy task. Also, I don’t want the camera drawing phantom power, so I decided to attach it to its own switch, requiring that I manually provide power to it in order to activate the system. The results are pretty sweet, but it’s starting to get kind of cramped in my nest of wires.
