Loop recording on a dashcam explained

What is Loop recording?

Loop recording is a feature on every dashcam which makes sure that the dashcam can keep recording even when the SD card is full. A dashcam with Loop recording stores the video files on the SD card in shorter fragments, usually 3 or 5 minutes. When the SD card is full, the dashcam automatically deletes the oldest file so there is space for a new file. This way you're sure that the latest trips are always stored on the SD card.

How do I keep files from being deleted by the Loop recording?

The Loop recording on a dashcam might be great for regular driving, but some files you want to keep for later. You might have seen something funny or remarkable on the road or worse, you got involved in an accident. You don't want these files to be automatically erased by te Loop recording.

Luckily a dashcam is able to either protect a video file or to store it in a separate folder to prevent it from being erased. There are usually two ways a dashcam is able to do this:

  • Manual SOS recording: Most dashcams have an SOS button to manually save the current file. One press on the button and the current recording is either protected or stored in a separate folder. Some dashcams also make a snapshot of the situation in case the SOS button is pressed.
  • G-sensor: All dashcams have a built-in G-sensor which senses vibrations (see section 3.1) and can therefore notice when there was an incident. When the vibrations reach a critical point the video is either protected or stored in a separate folder.
