What is a dash camera?
A dash camera is a small camera that connects to your 12V accessory socket and continuously records the surroundings of your vehicle. Often, they have a suction cup mount so you can place them behind your rearview mirror. In the event of an accident, you hit the "save footage" button and transfer the file to your computer. Your car insurer (and the police) may well use the footage in order to determine the timeline of events leading to a crash and to apportion blame.
