A rear-view camera is a safety feature installed in many vehicles that provides a view of the area behind the car. This camera activates when the vehicle is in reverse, displaying a live video feed on the dashboard screen. It helps drivers see obstacles, pedestrians, and other vehicles that may be in their blind spots, reducing the risk of accidents. These cameras often come with additional features, such as grid lines that assist in parking and distance markers that indicate how far away objects are. Rear-view cameras are part of a broader category of safety technologies, including parking sensors and 360-degree cameras, aimed at improving driver awareness.
