My rule was that the only wire allowed was a power wire. I didn't want POE because then you'd have to run that ethernet cable up to the pilothouse too.

Many of these cameras run on 5v with a 120vAC power adapter. In most cases, a 12v-USB converter is a very inexpensive way to get 5v out of a 12v house bank. It might take some wire splicing to re-use the power connector for the camera but that's pretty simple wiring. Reversing polarity is a good way to fry the camera.
