Will the dash cam automatically delete when full?

When the dash cam is full, it will automatically delete recordings. Most dash cams automatically overwrite old footage without requiring any settings - this is handled by the system automatically. However, some models may prompt you to confirm whether to overwrite or delete. In dash cams with automatic overwrite functionality, collision recordings will be automatically locked to prevent overwriting, and these locked files require manual deletion. This ensures evidence preservation after collisions. A dash cam is a device that records images, sounds and other data during vehicle operation. After installation, it can record the entire driving process with video and audio. The internal sensors can be set to different impact sensitivity levels - when external impact force exceeds the set value, the scene data will be recorded, providing evidence for traffic accidents.
As someone who frequently operates dash cams, I can tell you that when the memory card is full, most devices will activate the loop recording feature to automatically delete the oldest videos and free up space for continued recording. This is similar to a buffer system where new recordings overwrite old ones, ensuring uninterrupted monitoring. However, specific behavior depends on settings; if loop recording is disabled or certain files are marked as read-only (such as emergency-locked footage), the device may stop working when full. It is recommended that users check the settings menu during initial installation to enable the overwrite option, while also using high-speed SD cards and regularly formatting them to prevent space issues. For example, some high-end dash cams use file formats like MP4 that are easier to overwrite, whereas protected files may interrupt the recording process, leading to the loss of critical data. Therefore, developing a habit of monitoring storage status is crucial for driving safety.
