Nice large monitor, camera resolution but just not up to date ...

The Assembly worked well despite radebrechender instructions (China German). The monitor with its 7-inch a good size. Only the camera leaves much to be desired. Since I am not sure if it is 100% waterproof, it was mounted in the vehicle. The viewing angle ranges, could be greater. The on-screen (distance) Guides are unfortunately fixed, so you have very little adjustment, must just somehow be made to fit, say, you have to evaluate yourself where's could be tight and the camera according to the angle. The resolution is the major shortcoming of the set, there is a before and filmed with a mobile phone of the first generation, the resolution is just bad. All very washed out and the colors are not really true original.
Conclusion: enough to prevent rear-end collisions when reversing, no more.
Would be nice if you could connect a HD webcam it somehow ... That would be a much better picture quality!
