Most systems are powered from the monitor end, or a box that is closer to the monitor that everything plugs in to. You don't actually have a power wire to the camera that you hook up, nor the monitor.
I put mine in with two switches- one constant power from the house batteries, which I took from the headliner (where my control box is) and one that emulates a 12v reverse signal, because that was the only way to get the 3rd camera- my "3 camera" system is actually 2 camera inputs, 1 AV video input, and one camera input that only comes on when the reverse wire is hot- so I actually have 4 video inputs but one is not accessible with buttons.
Incidentally I used the reverse camera input inside the van, the actual rear camera is on one of the others. The switch works to quickly switch between two cameras ("reverse" and last AV).
