As more cars have in-dash video screens integrated into them, more and more cars feature backup camera systems to aid in driving in reverse and for safety. Even if a car does not include a camera, the vehicle can still be retrofitted with a backup camera system. The principle behind car backup camera systems is quite simple. A camera is mounted to the back center of the car usually above the license plate or rear insignia. The camera then automatically sends data to the in-dash video screen, allowing the driver to have instant feedback when driving in reverse. When shopping for a backup camera system, there are a few things to check in order to have the maximum safety and quality in a camera.
