The PLCM105 represents a triumph in innovation in rear view mirrors and backup cameras. First, check out the rear view display, featuring a 10.7" wide anti-glare mirror that can also function as a video screen. The screen size can be adjusted, so you still have room for your mirror -- choose a width from 4.5 to 8.5 inches. Second, check out the included rear backup camera with 420 lines of resolution, waterproofing, and nightvision for use any time, in any weather conditions. Plus, it can display "distance lines" on the screen, clearly marking how far you are from visible obstacles. The rear view mirror has two video inputs, so you can also hook up another device. It runs on your car"s 12 V power supply.
