4.2. Recording Modes
- Loop Recording: Automatically overwrites the oldest unlocked video files when the SD card is full, ensuring continuous recording without manual intervention.
- G-Sensor (Emergency Lock): The built-in 3-axis G-sensor detects sudden impacts or collisions. In such events, the current video footage is automatically locked to prevent overwriting, serving as crucial evidence.
