The more I look at it , the more I see it's not that good. I believe that it's 480p. Not HD.
Don't get me wrong. It does the job, yesterday I was backing up a parking space, and I had a truck right next to me, and I could see the road 120° in my screen.
In regards to the quality, I think to take advantage of the 8 inch screen, you will need a better on.
But now at least I have all the cables in the bumper, so swapping the camera is a 10 sec job
