I have wired in power for the cameras that connect wireless to the monitor powered by cigarette lighter. I have been through several sets and am still not really satisfied. Some of these issues may apply to you.
Some (many) signals from camera to monitor get lost or have major lag time. In units with this problem, it is worse at freeway speeds, and worse with metal trailers (mine is aluminum skinned). Listings about maximum distance from camera to receiver are often fictitious. I now have a setup recommended for big rigs and it works. I tried a separate antenna mounted on the front of the trailer and it didn't help.
Pairing the camera to the receiver was a problem for some units in that once I had them paired, they wouldn't always hold the setting. The instructions for what I have now say to power down the camera to allow pairing. You have a limited amount of time to rush between multiple points. I'm glad I have the right plug in my galley so I can pair with everything close by.
My first camera was mounted to the bumper and it was good for backing but worthless to see traffic behind me. So I added a camera above my galley door. That works okay for driving but is worthless for backing. I got a monitor that can watch two cameras so I don't have to keep pairing them. Different cameras have different angles of view and you'll want to get the right one. Too narrow and you can't see where you want, too wide and everything will be too tiny to identify. Mine are both too wide but it doesn't matter so much for backing because I only need to see near the trailer. With the higher camera, I can tell there is traffic behind me but can't tell what it is, how far back it is, or how fast it is approaching.
I didn't want my cameras on all the time but I wanted the ability to turn them on when driving day or night. So they are powered when I turn on my headlights, not to the backup light circuit. That has worked out well.
My cameras only last a couple of years. One of these days I might get smart and spring for the higher priced name brands with longer warranties instead of the amazon generics I've been using (Zeroxclub). But first I'll go out and measure what field of vision I want.
Oh yes, my cameras have night vision lights that I really like for backing at night. When driving forward at night lights don't make a difference, all I can see is a pool of headlights.
