- Plug the small end of the car charger into the camera's power port.
- Plug the larger end of the car charger into your vehicle's 12V cigarette lighter socket.
- Route the power cable neatly along the edges of the windshield and dashboard to avoid obstructing your view or interfering with driving.
4.4. WiFi APP Control Setup
The dash camera can be controlled and managed via a smartphone application.
- Download the "Viidure" app from the Google Play Store (for Android) or Apple App Store (for iOS).
- Turn on the dash camera.
- On your smartphone, go to WiFi settings and connect to the dash camera's WiFi network (usually named something like "LF-D306" followed by numbers). The default password is often "12345678" or "88888888". Refer to the camera's screen or included manual for the exact WiFi name and password.

5. Operating Instructions
5.1. Automatic Recording
Once powered on and connected to the vehicle's power supply, the dash camera will automatically begin recording when the vehicle starts. Recording will stop when the vehicle is turned off.
5.2. Loop Recording
The dash camera records video in continuous loops (e.g., 1, 2, or 3-minute segments). When the Micro SD card is full, the oldest unlocked video files will be overwritten by new recordings. This ensures continuous recording without manual intervention.

5.3. G-Sensor (Emergency Lock)
The built-in G-Sensor detects sudden movements or impacts (e.g., collisions). When triggered, it automatically locks the current video segment, preventing it from being overwritten by loop recording. These locked files are stored in a separate folder on the SD card.

5.4. 24-Hour Parking Mode
When enabled, the 24-hour parking mode allows the dash camera to monitor your vehicle even when parked. If an external force or impact is detected, the camera will automatically record and lock the video. This feature requires a hardwire kit (not included) to provide continuous power to the dash camera when the vehicle is off.
5.5. Night Vision
The LF-D306 is equipped with night vision technology to enhance video clarity in low-light conditions, ensuring important details are captured even at night.

- Cleaning: Use a soft, dry cloth to clean the camera lens and body. Avoid abrasive cleaners or solvents.
- SD Card Management: Regularly format the Micro SD card (at least once a month) through the camera's settings or the app to prevent errors and ensure smooth operation. Back up any important files before formatting.
- Temperature: Avoid exposing the camera to extreme temperatures for extended periods.
