- On the dash cam, enter the video recording mode and press the ▲ UP button to enter Wi-Fi connection mode. The dash cam screen will display the Wi-Fi SSID and password.
- On your smartphone, go to Wi-Fi settings, find the dash cam's SSID (e.g., "ActionCam_a0ac78358874"), and enter the default password (12345678).
- Return to the Viidure app. The app should now connect to the dash cam, allowing you to view live footage, access recorded videos, and adjust settings.
5. Operating Instructions
5.1 Basic Operation
- The dash cam will automatically power on and begin recording when your vehicle starts.
- Use the physical buttons on the dash cam or the smartphone app to navigate menus and control functions.
- The dash cam supports 3-channel simultaneous recording (Front, Internal, Rear). You can switch between different display modes on the dash cam screen to view individual channels or a split-screen view.
5.2 Advanced Features
- Loop Recording: Ensures continuous recording by overwriting the oldest unlocked files when the SD card is full. Important footage can be manually locked or automatically locked by the G-Sensor.
- G-Sensor (Gravity Sensor): Automatically detects sudden shakes or collisions and locks the current video segment to prevent it from being overwritten.
- Parking Monitor: When the vehicle is parked and the dash cam is connected to a continuous power source (hardwire kit required for 24H monitoring, not included), it will automatically start recording if a collision or vibration is detected.
- Night Vision: Enhanced with an f1.5 aperture and SONY STARVIS IMX662 CMOS, the dash cam provides clear video capture in low-light conditions.
- WDR (Wide Dynamic Range) & HDR (High Dynamic Range): These technologies optimize video quality by balancing exposure in challenging lighting conditions, ensuring clear footage in both bright and dark areas.
- Reversing Image Assist: When reverse gear is engaged (requires proper installation of the rear camera with reverse light connection), the dash cam screen can automatically switch to the rear camera view with parking guidelines.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the dash cam lens and screen. Avoid using abrasive cleaners or solvents.
- SD Card Care: Regularly format the SD card (at least once a month) through the dash cam's settings to ensure optimal performance and prevent data corruption. Use a high-speed (Class 10 or U3) micro SD card.
