A car camera, often referred to as a dash cam, is a small video recording device mounted on the dashboard or windshield of a vehicle. It captures footage of the road ahead and can also record inside the car. These cameras are primarily used for safety and security, providing evidence in case of accidents or disputes. Many car cameras come with features like loop recording, which automatically overwrites old footage, and G-sensors, which detect sudden movements and save important clips. Some models also offer GPS tracking and night vision capabilities, enhancing their functionality for drivers.
