Review on 📸 DOUXURY 4 Split Screen Backup Camera System with HD 1080P Monitor and DVR Recording by James Edwards

Great set, lots of cables Easy to connect Everything is a blind spot in my big truck. I actually have two camera systems, so a total of 8 cameras. One is wireless and I can't rely on it as I lose the picture when I need it most. The picture is a bit grainy. I liken it to a wireless system that works at the same time. I left the WiFi in place because I installed this camera system in various places on my truck. Wireless loses the signal at the most critical moments when it's needed, but when it does the picture gets a bit clearer. I tried adjusting the image in the menu but there is no refresh rate setting. If you look at the photos I drew the cameras to match the bumpers and one high above the windshield. The cameras are strong. Pros: Consistent image, easy switching between cameras, easy installation, well-developed customer support. Cons: slightly grainy
