Dash Cams are becoming increasingly popular as a way to document accidents, bad drivers, and to provide proof of fault for insurance purposes. A DashCam can be used to provide proof to police, as well as occasionally providing spectacular video of unexpected events.
In addition to providing evidence and security, some amazing videos have been captured of funny or scary events on the road, in driveways and parking lots.
Some professional series dash cameras can be used as part of a larger integrated security camera system but most consumer and standard dashcams record to a built-in microSD card. They may also include WiFi functionality for accessing video.
