• ADAS (Advanced Driving Alarm Systems): Enhances driving safety with Lane Departure Warning System (LDWS) and Forward Collision Warning System (FCWS). LDWS alerts drivers when the vehicle drifts from its lane at speeds over 50 km/h. FCWS calculates real-time distance to the vehicle ahead, providing 3-level warnings to prevent collisions.

4.3 ADAS Function Activation

After successful installation, it is recommended to check for updates within the DVR application settings to enable the ADAS function.

1. Access Settings: In the DVR application, navigate to the settings menu.
2. Check for Updates: Look for an option like "Check update" or "Application update" and initiate the update process.
3. Allow Permissions: Grant any necessary permissions requested by the application during or after installation/update.
4. ADAS Ready: Once the update is complete, the ADAS features will be active and ready for use.

5. Operating Instructions

5.1 Basic Operation

• The camera automatically starts recording when the car stereo powers on.
• Live video feed is displayed on your Android car stereo screen.
• Access recorded videos through the DVR application's playback function.

5.2 Loop Recording

The camera continuously records video in segments. When the memory card is full, the oldest unlocked video files are automatically overwritten by new recordings. This ensures that you always have the most recent footage available.

5.3 G-Sensor Activation

In the event of a sudden impact or collision, the built-in G-sensor detects the event and automatically locks the current video segment, preventing it from being overwritten by loop recording. These locked files are crucial for evidence in case of an accident.

5.4 ADAS Features

Once activated (refer to Section 4.3), the ADAS system provides audible and visual alerts for:

• Lane Departure Warning System (LDWS): Alerts if your vehicle drifts out of its lane without signaling.
• Forward Collision Warning System (FCWS): Warns you if you are approaching a vehicle ahead too quickly.

6. Maintenance

6.1 SD Card Management

• Regularly format the Micro SD card (at least once a month) to maintain optimal performance and prevent data corruption.
• To remove the SD card, gently push it inward until it clicks, then release to eject.
• It is recommended to use a high-quality Class 10 or higher Micro SD card for reliable recording.

6.2 Cleaning

• Use a soft, dry cloth to clean the camera lens and body.
• Avoid using abrasive cleaners or solvents that could damage the device.

7. Troubleshooting

• Camera Not Detected: Ensure the USB cable is securely connected to both the camera and the car stereo. Verify that the car stereo's USB port is functional. Restart the car stereo.
• APK Installation Failure: Check if your Android car stereo has sufficient storage space. Ensure you are installing the correct APK file. If issues persist, try downloading the APK from the manufacturer's support website if available.
• ADAS Not Functioning: Confirm that the ADAS update has been successfully installed (refer to Section 4.3). Ensure the camera is properly aligned and has a clear view of the road. ADAS performance can be affected by windshield angle or obstructions.
• Poor Video Quality: Clean the camera lens. Ensure the camera is securely mounted and not vibrating. Check the recording resolution settings in the DVR application.
• SD Card Errors: Format the SD card. If errors persist, try using a different, high-quality Micro SD card.
