4.2 Installing the Rear Camera (Optional)
- Connect the rear camera cable to the AV-IN port on the main dash cam unit.
- Route the cable neatly along the vehicle's headliner and pillars to the rear of the vehicle.
- Mount the rear camera on the rear windshield or near the license plate using the adhesive pad or screws. Ensure it has a clear view of the rear.
- If connecting to reverse lights for parking assistance, consult a professional for wiring the red wire of the rear camera cable to your vehicle's reverse light power supply.
4.3 Power Connection
- Insert a high-speed MicroSD card (Class 10 or higher, up to 32GB recommended) into the TF Card Slot. Format the card in the device settings before first use.
- Connect the car charger to the USB port on the dash cam.

5.3 Recording Modes
- Loop Recording: The dash cam continuously records video in segments (e.g., 1, 3, or 5 minutes). When the memory card is full, it automatically overwrites the oldest unlocked footage. Adjust segment length in the settings.
- G-Sensor (Emergency Recording): In the event of a sudden impact or collision, the built-in G-sensor detects the event and automatically locks the current video file, preventing it from being overwritten by loop recording. Adjust sensitivity in settings.
- Motion Detection: When enabled, the dash cam will automatically start recording if it detects movement in front of the vehicle while parked. This feature requires a continuous power supply (e.g., via an optional buck line).

With the optional buck line installed, the dash cam can monitor your vehicle while parked. If an impact is detected, the device will automatically power on and record a short video, then power off. This protects your vehicle even when the engine is off.
6. Maintenance
- Cleaning: Use a soft, dry cloth to clean the lens and screen. Avoid using abrasive cleaners or solvents.
- Temperature: Do not expose the device to extreme temperatures (above 60°C or below -10°C) for extended periods.
