Guide
Most dashcams record continuously in short loops while the vehicle supplies power. Parked recording is separate and depends on the camera, installation and power settings.
Usually, yes. Once powered, a typical camera writes consecutive clips to its memory card. This loop is continuous, but the archive is not permanent because the oldest ordinary files are overwritten when storage fills.
Loop recording divides a journey into manageable files. A collision sensor or manual save button can protect an important clip, though protected storage can also fill and should be checked.
Not from a switched accessory socket after that socket loses power. Parking mode needs an approved constant-power connection, such as a hardwire kit, and must be supported by the camera.
Compatible hardwire kits may offer low-voltage cutoff and timers. Select settings appropriate for the vehicle and have unfamiliar electrical work handled by a qualified installer.
Retention varies with card capacity, resolution, channel count, bitrate and driving time. Save an important file promptly to another device rather than relying on the loop.
Check the camera's status light, screen or spoken prompt as described in its manual. Format compatible storage as directed and review sample clips periodically.
Common questions
They generally record in a loop whenever they receive power. That does not mean every clip remains stored indefinitely.
Only with a supported parking setup and a suitable power source. Many accessory sockets switch off with the ignition.
Loop recording overwrites the oldest unprotected files when the card is full. Locked or protected clips are handled separately by the model.
A poorly configured constant-power installation can draw from the vehicle battery. Use compatible battery protection and follow the installer's or manufacturer's guidance.

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.
