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 Kevin Singh

The overall installation is very simple, especially when installed in a van. Sharp picture quality with wide angle. The teaching, if I may say so, is in need of improvement. Your setup will work much better than mine. If you test the cameras first to see how they're oriented, you can change their orientation in the case, but I couldn't find a way to do that in the menu structure. First, the two side cameras were misaligned, one upside down and the other sideways. I couldn't find any solution in the software other than mirroring the image. So I solved this problem by loosening the 4 screws that "fix" the cameras in position and then rotating the cameras to the correct orientation. The side chambers have a spherical arrangement. Overall they are great for the price and the DVR function works automatically and in a cycle. Would 100% recommend them to anyone looking for a backup/DVR/security camera system. I hooked mine up to the bus power supply, but when it's done I'll move it to the side of the sun house to use as collateral.
