Does the dash cam automatically delete when full?

Most car dash cams will automatically overwrite previous videos, or more professionally termed as loop recording. When the memory card is full, the dash cam will delete the earliest recorded videos to free up space for storing new videos, allowing the dash cam to continue recording. The functions of a dash cam are as follows: 1. Protect the legal rights of drivers. In case of collisions with pedestrians crossing the road or cyclists and motorcyclists, drivers may face extortion. With a dash cam, drivers can provide valid evidence for themselves. 2. When courts handle road traffic accident cases, sentencing and compensation will be more accurate and evidence-based, also providing evidence for insurance claims. 3. Playback of the recorded footage makes accident responsibilities clear at a glance, enabling traffic police to handle accidents quickly and accurately. This allows for quick clearance of the scene to restore traffic while preserving valid evidence of the incident, creating a safe and smooth traffic environment. 4. In case of encountering professional scammers or road robbers, the dash cam can provide decisive evidence for solving the case: the scene of the incident and the appearance characteristics of the criminals, etc.
As someone who drives frequently on the road, I can tell you that when the dashcam is full, it usually automatically deletes old videos to continue recording new ones. This is called loop recording, and it's quite intelligently designed. During my several long-distance trips, such as driving to mountainous areas, it smoothly overwrote files without requiring manual space clearing. However, it's important to buy a high-speed SD card with fast enough write speeds to avoid lag; the card may wear out over time, so I format it every three months for maintenance. Additionally, setting high-resolution recording creates large files that consume space quickly, so I recommend medium quality for balance. A simple maintenance habit: just glance at the remaining space monthly, ensuring it captures critical moments during travels without hassle. Overall, automatic deletion is standard, but pairing it with regular checks makes it more reliable.
