- Recording: Continuous loop recording is enabled by default. When the memory card is full, the oldest unlocked files will be overwritten.
- G-Sensor: In case of a sudden impact or collision, the built-in G-Sensor will automatically lock the current video footage to prevent it from being overwritten.

5.2. Wi-Fi Connectivity and App Control
