Super Night Vision:
Equipped with an F1.8 large aperture, WDR (Wide Dynamic Range), and a 6-layer glass lens, the dash cam captures clear and sharp footage in low-light conditions, ensuring detailed number plates and road signs are visible day and night.

24-Hour Parking Monitor:

- G-Sensor: Automatically detects sudden shakes or collisions and locks the current video footage to prevent it from being overwritten, securing critical evidence.
- Loop Recording: Ensures continuous recording by automatically overwriting the oldest unlocked files when the memory card is full.

7. Maintenance
- Clean the Lens: Regularly clean the camera lens with a soft, lint-free cloth to ensure clear video quality.
- Format MicroSD Card: It is recommended to format the MicroSD card periodically (e.g., once a month) to maintain optimal recording performance and prevent data corruption. Back up any important files before formatting.
- Operating Temperature: The dash cam is designed to operate in temperatures from -30℃ to 80℃ (-22℉ to 176℉). Avoid exposing the device to extreme temperatures outside this range for prolonged periods.

8. Troubleshooting
If you encounter any issues with your Otovoda B-T51 Dash Cam, please refer to the following common solutions:
- Device not powering on: Ensure the car charger is properly connected to both the dash cam and the vehicle's power outlet. Check if the vehicle's ignition is on.
- Recording issues: Verify that the MicroSD card is correctly inserted and formatted. If the card is full, loop recording should overwrite old files, but ensure no critical files are locked. Try formatting the card.
- WiFi connection problems: Ensure the dash cam's WiFi is enabled and your smartphone is within range. Re-enter the WiFi password if necessary.
- Poor video quality: Clean the camera lens. Check the recording resolution settings in the app.
