3.3 Power Connection
Connect the provided car charger to the dash cam's power input port and plug the other end into your vehicle's cigarette lighter socket. The dash cam will automatically power on and begin recording when the vehicle starts.
For 24-hour parking monitoring, a hardwire kit (sold separately) is required to provide continuous power to the dash cam even when the vehicle is off.
4. Operating Instructions
4.1 Basic Recording
Once powered on, the dash cam will automatically start loop recording. Video files are saved in segments (e.g., 1, 3, or 5 minutes) to the MicroSD card. When the card is full, the oldest unlocked files will be overwritten.

4.2 G-Sensor (Emergency Recording)
The built-in G-sensor detects sudden shakes or collisions. When triggered, the current video segment is automatically locked and saved to a protected folder, preventing it from being overwritten by loop recording. This ensures critical event footage is preserved.

4.3 Parking Monitoring
With a hardwire kit (sold separately), the dash cam can monitor your vehicle for 24 hours. It supports two parking modes:
- Time-Lapse Recording: Records continuously at a low frame rate to save storage space.
- Collision Detection (G-Sensor Emergency): Activates recording when a collision is detected.
