Review on Enhanced eRapta 3.0 Backup Camera System with 7'' Monitor: RV Trucks Side/Front/Rear View Back Up Camera DVR System, IP69 Waterproof, 4 Cameras 4 Channels - Prevent Blind Spots, EHD4 by Sean Young

So far, so good. Installed on our school bus and enjoyed the extra viewing angles we now have on the screen and it's capturing! Everything arrived well packaged and works perfectly after installation. As another reviewer mentioned, the instructions are not very good. I'm lucky to have an assistant who knows about wiring, otherwise I'd have a hard time installing this myself. The cameras and their cables are easy and straightforward to install. The wiring to the car is the tricky part. It's not hard to do once you know what you're doing, but the instructions don't give you much guidance on how to do it. I gave 5 stars because the picture quality is great and it works exactly as advertised.
