4.6 Loop Recording & G-Sensor Lock
The V620 features continuous loop recording, automatically overwriting the oldest files when the SD card is full. The integrated G-sensor detects sudden impacts or vibrations, automatically locking the current video segment to prevent it from being overwritten, ensuring critical event footage is preserved.

This image illustrates the G-sensor's function, which automatically locks video footage during sudden impacts to prevent overwriting, ensuring critical evidence is saved.

Protect your vehicle around the clock with three advanced parking modes (requires an optional hardwire kit):
- Motion Detection: Records when movement is detected around your parked car.
- Collision Detection: Activates recording upon detecting an impact to the vehicle.
- Time-Lapse: Records continuously at a low frame rate to save storage space while capturing extended periods.

5. Maintenance
5.1 SD Card Care
To ensure reliable recording, it is recommended to:

5.2 Cleaning
Gently wipe the camera lenses with a soft, lint-free cloth to maintain clear video quality. Avoid using abrasive cleaners or solvents.
6. Troubleshooting
If you encounter issues with your LINGDU V620 dash cam, refer to the following common solutions:
- Camera Not Turning On: Ensure the power cable is securely connected to both the dash cam and the car's power source. Check the car charger for proper function.

- Video Playback Issues: Ensure the LINGDU App or desktop player is up to date. If playing directly from the SD card, try formatting the card.
- WiFi Connection Problems: Verify that your phone's cellular data is turned off when connecting to the dash cam's WiFi. Ensure you are within 10 feet of the dash cam for a stable connection.
