What is loop recording on a dash cam?
Loop recording on a dash cam allows for continuous recording even if the SD memory card reaches full capacity. This means older files are overwritten once the SD card reaches its file size limit. The Dash Cam will be recording on a continuous loop when powered on, so will always be recording.
In the event of an 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. Therefore, important clips that can be used for insurance purposes or sending to the Police will stay locked on the card and will not be deleted.
When reviewing footage to share, instead of recording one large file, loop recording sorts each file into manageable segments at around 3 minutes. This makes the file easy to download and transfer. This is particularly useful for Wi-Fi enabled Dash Cams, as the file can be downloaded quickly and shared to your phone, tablet.
With loop recording, the card will need to be formatted at some point. This is when there is a build-up of protected files stored on the card, which shortens the recording time for the dashcam. It is generally recommended to format the SD once a month to free up space on the SD card. The card can easily be formatted via the setup to delete all files, including any protected files.
Dash cam loop recording time
The default recording time for most dash cams is three minutes for each file but this can be increased to five minutes, making each file size manageable and easy to view when playing back footage. At 1080p HD, it will give up to 4 hours of recording before the cam loops over. At altered recording resolutions, this can be either increased or decreased. For example, recording at 720p resolution will increase the recording time compared to recording at 4K Ultra HD.
