A rearview camera is a safety feature found in many modern vehicles that helps drivers see what is behind them when reversing. It uses a small camera mounted on the back of the car to capture a live video feed, which is displayed on a screen inside the vehicle. This technology makes it easier to spot obstacles, pedestrians, or other vehicles, reducing the risk of accidents. When the driver shifts into reverse, the rearview camera activates automatically, providing a clear view of the area behind the car. Some systems also include guidelines on the screen to assist with parking and maneuvering, making it a valuable tool for both new and experienced drivers.
