VECLESUS VMW7-4C 1080P Wireless Backup Camera Kit, 7” IPS HD Monitor & IP69K Waterproof High Speed Stable Transmission 4 Backup Cams for Trucks, RVs, Trailers, Bus, Harvester, Motorhome Large Vehicles

I normally do not review but this product deserves one. I bought the vmw7-4c ( 4 camera model). I installed 2 on the back of a box truck and 1 additional camera on 2 trailers. On the truck 1 looks down for hitching and the other is set to view the trailer and load. I wired through the running lights so i can turn on to use as a monitor or back up cam. Fairly easy install. Great connectivity with the cameras even on the back of the trailer 25 feet away. Comes with an external antenna if needed but i did not use it. Nicest feature is the ability to flip and rotate each camera view individually from the main head.
