Review on 🚗 Enhanced Safety: GreenYi HD Car Backup Camera with Dynamic Trajectory Guide Line, Waterproof Night Vision & Wide 155° View by Rob Jimenez

First of all I have to say that the build quality of this device seems impeccable. It's a bit heavier compared to other rear cameras I own. It also has a subdued profile so it doesn't stand out like other cameras. I really wanted this camera to work with my DVR. It's not sending the correct signal to any of the rear cameras/AV inputs on my four dash cams. My dash cams came with rear cameras so I know the input is working. I liked the small profile of this "universal" camera, so I was excited to replace my existing rear cameras with this GreenYi camera. "Universal" is a misnomer it doesn't deserve because I know for sure it's not universally compatible. I went to great lengths to make it work. I've tried many different adapters and even tried video testing and changing pinouts with custom adapters, knowing that some manufacturers use different pinouts than others. As a result, I came to the conclusion that the signal is not compatible with my DVRs. It can use an analog signal and newer DVRs need a digital signal. It was a waste of my personal time spent trying to get it to work. I hope this works for your setup, and if it does, that's awesome. I just want it to work for me.
