A dash cam is a compact onboard camera mounted on a vehicle’s dashboard or windshield that continuously records the road ahead (and sometimes the interior or rear view) while you drive. It automatically starts recording when the vehicle is turned on and saves footage in a loop, ensuring that important moments such as accidents, sudden braking, or unexpected incidents are captured in real time. Many modern dash cams come equipped with features like night vision, motion detection, GPS tracking, parking mode, and G-sensors that lock crucial video files during impacts, making them highly useful for insurance claims, legal evidence, driver safety, and monitoring vehicle activity when parked.
