4.3 Exposure Compensation

4.4 G-Sensor and Loop Recording
- G-Sensor: This sensor automatically detects sudden impacts or collisions. Upon detection, it locks the current video footage to prevent it from being overwritten, preserving critical evidence.
- Loop Recording: The device continuously records by overwriting the oldest footage when the memory card is full. You can set recording segments to 1, 3, or 5 minutes. This ensures uninterrupted recording.

4.5 Motion Detection
When enabled, motion detection initiates recording if vibration or other abnormalities are detected around the parked vehicle. This feature enhances security and provides surveillance when the vehicle is unattended.
- Activate motion detection through the device settings.
- Recording will automatically start if movement is detected.
