Wired vs Wireless Rear View cameras - Pros / Cons?

It would depend on the camera and the signal strength. I installed a license plate mounted camera with a monitor built into the rear view mirror. I had to add wire to the transmitter and extend it up to the engine compartment to get a good signal. It may as well have been a wired system because I had to get within about six feet of the receiver. It works pretty good though and allows me to see directly behind my RV rather than at the bumper.
