A rear-view camera is a safety feature installed in many vehicles that provides a view of the area behind the car. It uses a small camera mounted on the rear of the vehicle, which displays a live video feed on a screen inside the car. This helps drivers see obstacles, pedestrians, or other vehicles when reversing, reducing the risk of accidents. Typically, the rear-view camera activates automatically when the vehicle is put in reverse. Some systems also include guidelines on the display to assist with parking and maneuvering. This technology is part of a broader category of driver assistance systems aimed at enhancing road safety.
