A rearview camera is a safety feature that is designed to help drivers see what's behind them when they are backing up. It typically consists of a small camera mounted on the back of the vehicle, which sends an image to a display screen in the dashboard or center console. This allows the driver to have a clear view of any obstacles or pedestrians that may be behind their car while driving in reverse. The use of rearview cameras has been shown to significantly reduce the number of accidents caused by backover incidents, making them an important safety feature for many modern vehicles.
