Review on HD Backup Camera System Kit With Monitor - ZEROXCLUB 9, Loop Recording, IR Night Vision Waterproof Camera W/ Safe Parking Lines For Bus, Semi-Truck, Trailer & RV (BY902A) by Jyothish Pillai

This was so easy to install. First I tested it on my bench. I didn't have to pair it for it had already been paired. Picture was perfect. All that is needed is a source of power from the trailer. I tied it into the middle running light at the top of the trailer. I would have hidden the wire but there was a plate inside the wall between where I wanted to install the camera and the light. After installing the camera I placed the monitor on the dash, hooked the trailer up to the truck, turned on the running lights, turned on the power to the monitor and I had a perfect picture. I did not need an antenna extension and have had no trouble with loosing the signal from the camera to the monitor. I have a Tundra pickup and a 22 foot Coachman Spirit trailer. Now I can see my wife's guidance when she is behind the trailer no matter which way I have the truck turned, wonderful.
