Have you ever been in an accident, not been at fault, and wished you had some way to prove it? If only there was a witness to back up your story to the cop, judge or insurance company representative. Enter the car digital video recorder (DVR).
Car DVRs, also known as car black boxes and dashboard cameras, are an aftermarket car accessory designed to deal with the unpredictability of other drivers on the road and drivers’ misinterpretation of traffic rules. By recording live streams from the front and rear of the vehicle, car DVRs provide information to insurance companies, the legal system and others in the event of an accident.
With the need for improved video quality and the wider acceptance of full HD content, car DVRs have advanced from a single-channel analog D1 resolution camera to multi-channel up to full HD (1080p) wide-angle cameras. For example, a two-channel Car DVR has two cameras—one for the front of the car, and the other one for the rear. In addition, many sophisticated algorithms are being continually added to these cameras, giving them the “smarts” to detect people, objects and even sounds around them.
As with any good and successful product, the first rule is to get the basic features right. Considering the car DVR, we believe that nothing is more basic than image quality. Even at night or in a dark parking garage, the camera should be able to capture clear images of people, license plates and other objects. It’s important that if a vehicle has been damaged, the driver has a recorded video with clear images of the person responsible for the damage as well as the vehicle’s license plate. To overcome this challenge, TI’s DaVinci video processors integrate a high-quality noise filter in order to provide low-light imagery.
