Car cameras, also known as dash cams, are small video recording devices mounted on the dashboard or windshield of a vehicle. They capture video footage of the road ahead and can provide evidence in case of accidents, helping to clarify what happened during an incident. Many models also feature loop recording, which automatically overwrites old footage, ensuring that the camera continuously records. In addition to accident documentation, car cameras can enhance safety by offering features like GPS tracking, night vision, and collision detection. Some advanced models even include rearview cameras to monitor the area behind the vehicle, making parking and reversing safer.
