Does the dash cam have an automatic deletion function?

Dash cams have an automatic deletion function, which generally deletes some previous information automatically when the memory is full. The following is a related introduction about dash cams: Time options: The loop recording settings of dash cams usually have different time options such as 1 minute, 2 minutes, 3 minutes, 5 minutes, 10 minutes, etc. After recording, it moves to the next segment. Setting the loop time to 3 or 5 minutes is recommended: When setting the loop time for dash cams, it should not be too short or too long. If the recording time is too short, the video will be split into more segments, increasing the chance of frame loss. If the time is too long, the number of stored videos will be very small and quickly overwritten. It is recommended to set it to 3 or 5 minutes, which is most appropriate.
Dash cams generally have an automatic deletion feature, primarily based on a loop recording mechanism. While you're driving, the device continuously records videos and saves them as new files. Once the memory card is nearly full, it automatically overwrites the oldest video files, ensuring new content can be saved without interruption. From my experience, using a high-capacity card can extend the loop recording duration, but this is the default setting. Some advanced models also support event protection, such as automatically locking footage during collisions to prevent deletion—quite smart. I've also come across settings in mobile apps that allow adjusting the loop interval or file size to control deletion frequency. Automatic deletion eliminates the hassle of manual cleanup, keeping the dash cam always ready—a basic yet practical feature. If you find the overwriting too fast, simply switch to a higher-capacity SD card; no need to worry about it randomly deleting important footage.
I've been driving for fifteen years, and a dash cam is an essential tool for my daily routine. The auto-delete feature saves me a lot of hassle, eliminating the need to constantly remember to delete old recordings. Initially, I was worried that a full memory card might cause loss of new footage, but I later discovered it automatically overwrites expired files, much like a looped playlist. My car's device is a basic model, with a loop recording option in the settings menu. Once enabled, storage management runs smoothly. Occasionally, a card alert prompts me to check if the settings are too tight, but the deletion process is entirely automatic, without interfering with driving. After upgrading to a larger memory card, the loop interval extended, covering a full cycle only every two weeks. This feature is well-designed, avoiding distractions from manual operations and enhancing the device's durability. I recommend beginners stick to the default settings to prevent maintenance oversights that could compromise driving safety.
