In order to record all the time you are driving, dash cams are designed to record on a “loop”. Once the recording space is full, it will start to record over the data that is oldest. So your device will always preserve the most recent data. The dash cam will record directly onto a standard format SD card.

Do dash cameras always record?

The Dash Cam records on a continuous loop when powered on, so it is always recording. In the event of a driving incident, any files that have been protected by activation of the G-Sensor, or by manually pressing the file protect button, will not be overwritten and will stay on the SD card.

Does a Dash Cam work when car is off?

Dash cams typically just turn on and off with the engine, automatically recording video while you drive. Dash cams can also be set up to stay on and keep recording even when the car is parked and the engine is off, thereby functioning as a surveillance camera system while you're away from your vehicle.
