Anyone tried Bluetooth Backup Cameras?

I changed my cameras to the Voyager monitor and cameras using my old cables. Great picture. I added a wireless bluetooth Garmin camera on the side of the coach for alignment with fuel pumps. The picture from the bluetooth camera is sufficient but is not near the quality of the wired cameras. It also sometimes will get interference from fluorescent lights, etc. I should add that a wireless camera is not really wireless since it requires power to the camera and a means to turn it on and off.
