Review on 📷 1080P 10.1 inch Backup Camera Monitor with Built-in 128GB DVR Video Sound Recorder - RV Truck Trailer Rear Side Front Reversing View Wired System - 5 Split Large Screen Waterproof Design to Avoid Blind Spots by Joe Murphy

Thing works great. The only thing I had to change was the arrangement of the windows on the screen. I wanted a full screen of what was behind me while driving, but the only way to get that was to power the rear camera sensor. This would make me lose the ability to trigger the left and right cameras when turning, so I put together some CD4011BE (NAND) and CD4073BE (AND) logic gates to disable the reverse trigger when the turn signal is on. Works great and gives me full screen rear and left and right all the time when the turn signal comes on. The front end is only connected for DVR service.
