A rearview camera is a safety feature installed in many vehicles that provides a view of the area behind the car. It helps drivers see obstacles, pedestrians, or other vehicles when reversing, reducing the risk of accidents. The camera typically displays a live video feed on a screen inside the car, often accompanied by guidelines to assist with parking. These cameras became more common after regulations mandated their inclusion in new vehicles sold in the United States starting in 2018. They are part of a broader category of safety technologies, which also includes parking sensors and blind-spot monitoring systems.
