Not only that, but they have an input for another camera. If you don't like the one supplied, then get another camera and just use the display.They basically use a fish eye lens so distance is distorted. At night unless someone has their lights on the view is pretty dim. You can pick up the reflected light off bumpers but that is about it. When backing into a parking space at night with marginal lighting, the objects behind you come into view as you get close to them, but I wouldn't rely on it on the interstate. In harsh sunlight their is some burn out but give it 15 seconds and it clears. There is a button that is supposed to help with low light or maybe its for the dimming of the bright sunlight. I don't use it because I have already started backing before thinking of using it. Compared to the Chase Cams, it is a bargain though.
