Loop Recording
The dashcam utilizes seamless loop recording. When the MicroSD card reaches its full capacity, the oldest video files are automatically overwritten by new recordings. This ensures continuous operation without manual intervention.

Locking Important Footage
In the event of a sudden impact or emergency, the built-in G-Sensor will automatically detect the event and lock the current video segment. This prevents the footage from being overwritten by loop recording, preserving critical evidence.
