Check out the PLCM7500, an awesome 7 in. Window Suction-Mount LCD Widescreen Monitor and License Plate Mount Backup Color Camera with Distance-Scale Line from Pyle. This kit includes a waterproof, low-light-vision equipped, universal-mount color rearview camera and suction-cup mount screen for the inside of your car. The camera outputs crystal clear video over an RCA jack–even in relatively low light. The LCD monitor detects when you back up and shows the camera on screen. Perfect for backing into tight spots or moving in reverse when visibility is limited, it’s like having an extra eye. It’s also equipped with a distance-line mode to show you how far away you are from other objects in the camera’s viewfinder.
