Dashboard cameras, often called dash cams, are small video recording devices mounted on the front windshield of a vehicle. They continuously record the view through the windshield while driving, capturing important footage in case of accidents or incidents on the road. Many dash cams also have features like loop recording, which overwrites old footage, and G-sensors that automatically save video during sudden movements. These cameras can provide valuable evidence in disputes over accidents, helping to clarify what happened. Some models also include rear-facing cameras for additional coverage, and many can connect to smartphones for easy access to recorded videos.
