How do front and rear dash cams work?

Dashcams are a way to capture footage of your drive, and there are two main types: front-facing and rear-facing. Front-facing dashcams record what is happening in front of the car, while rear-facing cameras record the area behind the car. Both work similarly: they consist of a camera mounted on the dashboard or windscreen and a storage device, usually a microSD card, to store the footage. The footage is usually recorded in MP4 or AVI format, and most dashcams come with software that allows you to view and edit it.
