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

While testing this item prior to installation, my monitor/DVR overheated and shut down. I tested it again and found that 2 cameras were overheating and going to black screens. When checked, the chambers felt HOT. There's no way these black metal cases will work better mounted on my RV and baked in the sun. Image quality was also poor and had iridescent artifacts. And do you see this SD card in the picture? Yes it is not included, read the fine print. This will be sent back to Revain immediately and I recommend you avoid this.
