A dash cam, short for dashboard camera, is a small video camera mounted on a vehicle's dashboard or windshield. It records the view through the front window while driving, capturing video footage of the road and surroundings. Dash cams are often used for safety and security, providing evidence in case of accidents or disputes. Many dash cams also feature additional functions, such as loop recording, which continuously overwrites old footage, and G-sensors that detect sudden movements or impacts. Some models even offer GPS tracking and night vision capabilities, enhancing their usefulness for drivers and fleet operators alike.
