How a dash cam works

To put it simply and briefly, a dash cam records a variety of data and stores it for a period of time, which can be used later if there’s an accident or road rage incident to prove that you’re not at fault. (We’re assuming you’re not at fault; more on that in a second.) The dash cam obviously records video, but most also record audio. Many of the more advanced units come with GPS, which can be used to determine vehicle speed, and some come with accelerometers which can sense a crash and preserve the footage taken just before the accident.

Almost every dash cam will record as soon as it gets power — so, when the car turns on, and the cam is plugged into ignition-controlled power, it’s recording. Beyond that, there are a huge number of variations. Some have LCD screens built in, so you can review the footage without having to plug the unit or memory card into a computer.

Most have built-in flash storage, and many are expandable. When the storage runs out, the camera just overwrites the existing data. That’s fine; no one needs to see you run errands a few days before an accident occurs. If there’s footage you’d like to save, just make sure to offload it before it’s overwritten.
