Guide
Loop recording saves video in short clips and replaces the oldest unprotected files when storage fills. Protected event clips are handled separately.
Dash cam loop recording divides continuous video into short files. Once usable card space is full, the camera deletes the oldest ordinary clip to make room for a new one, so you do not have to clear routine footage manually.
A G-sensor or manual save button can mark a clip as an event and protect it from normal loop overwriting. Protection behavior and folder limits vary, so copy important evidence off the card promptly.
Shorter files are easier to manage and reduce the amount of footage affected if a file is damaged; longer files create fewer boundaries. Use a supported setting and remember that clip length does not change total card capacity.
Protected event files, parking recordings or photos may occupy space that ordinary looping cannot reclaim. Review these folders and follow the manual’s formatting schedule instead of deleting unknown system files individually.
Stop recording only when safe, lock the relevant clip if the camera provides that control and copy it to another device. Include the clips immediately before and after the event because the key moment may cross a file boundary.
Common questions
It normally replaces the oldest unprotected video, not every file at once. Locked clips and other folders may follow different storage rules.
For normal driving, leaving it on usually prevents routine footage from filling the card. Turn it off only when the manual or a specific evidence-handling need calls for it.
A properly saved event clip should be protected, but no system is infallible. Copy important files as soon as practical and check that the event folder is not full.
Only if the dash cam supports parking mode and has a suitable power supply. Parking files may use motion, impact or time-lapse recording rather than the same behavior as normal driving.
Keep exploring
VIOFO A229 Pro 2CH is our broad recommendation for detailed front and rear coverage. Garmin Mini 3 favors discretion, while Garmin X310 is the sharper single-camera choice.
A front and rear dash cam records both directions and can provide context a single lens misses. Check the rear-camera cable route and simultaneous recording resolution before buying.
The A329S serves buyers seeking high-detail multichannel recording; A229 models cover more moderate dual-camera needs, while A119 Mini 2 is the compact front-only option.
Start with the coverage you need: front-only, front and rear, cabin or a wider multi-camera view. Then compare recording detail, storage and power requirements.
