Backup camera kits available?

[PxTx]

A guy I work with has a quadrasteer Denali pick-up. He has a wireless camera setup and hooks to a trailer nearly daily. At first he thought mounting the camera on the tag frame was good. Later he realized they can break.

Hindsight being 20/20 he's felt it is better to mount the camera to the trailer. What is nice about that, you could certainly make it so that you could mount it on the front for hook-up, then move it to the rear so see what is behind you when towing.

Resolution is weak on the cheap camera kits, so I would assume you get what you pay for.
