Review on HD Backup Camera System Kit With Large Monitor And Safe Parking Lines - WATERPROOF IR Night Vision Camera For Bus, Semi-Truck, Trailer, RV - Loop Recording - ZEROXCLUB 10, Model BY104A by Julius Robinson

Got the 7" and 2 cams, tested it and the picture looks really good, the only improvement I would suggest is make the antenna a flexable line out of the back as you can't fully spin the camera around because it wont clear the bracket.

There are 4 longer brackets included(2 per camera) that do clear the antena but also moves the camera a lot farther out(rather have it as close as possable for less chance of it vibrating loose or wind damage). Takes a bit of time to go throught all the settings but so far I like the system
