Important 4G Network Compatibility Notice:
This device only supports 4G bands B1 (2100Mhz) and B3 (1800Mhz). It is NOT compatible with most 4G networks in North & South America (e.g., USA, Canada, Mexico, Argentina, Chile, Colombia, Peru, Ecuador). If your local network does not support B1/B3, the 4G functionality will not work. Other features, such as video recording and Wi-Fi hotspot, will still be available without a SIM card.
3.3 Mounting the Dash Cam
- Choose a location on your windshield that does not obstruct your view, typically behind the rearview mirror.
- Clean the windshield surface thoroughly.
- Attach the dash cam mount to the windshield.
- Secure the dash cam to the mount. Ensure the lens has a clear view of the road.
3.4 Connecting Power
The dash cam can be powered via the included car charger or OBD fuse cable.
- Connect the appropriate power adapter (car charger or OBD fuse cable) to your vehicle's power source.
- Connect the Type-C end of the power cable to the dash cam's input port.
- Route the cable neatly along the windshield and dashboard to avoid interference with driving.
3.5 Installing the Rear Camera
- Mount the rear camera on the rear windshield or near the license plate, ensuring a clear view.
- Connect the rear camera cable to the designated input port on the main dash cam unit.
- Route the cable carefully to avoid damage and ensure it does not interfere with vehicle operations.
4. Operating Instructions
4.1 Basic Operation
Once powered on, the dash cam will typically start recording automatically. The display will show live footage from the front and/or rear cameras.

4.2 APP Remote Monitoring (CloudSpirit App)
The CloudSpirit app allows you to remotely monitor your vehicle, track its location, and manage recordings.
- Download the CloudSpirit app from your smartphone's app store (compatible with Android 10+ and iOS 11.0+).
- Register or log in to your account.
- Add your dash cam device by scanning the QR code on the device or entering its ID.
- Once connected, you can access features such as live video streaming, remote playback, GPS track history, and one-click capture.


4.3 GPS Tracking
The built-in GPS and Beidou modules provide accurate location tracking and trip history.
- View your car's real-time location on the CloudSpirit app.
- Access historical driving routes and playback on the app.

4.4 Parking Monitor
The parking monitor feature protects your vehicle when it's parked and the engine is off. This feature requires the OBD fuse cable for continuous power.
- The built-in G-sensor detects impacts or vibrations.
- Upon detection, the dash cam automatically wakes up and records video.
- Notifications can be sent to your CloudSpirit app if an event occurs.

4.5 Wi-Fi Hotspot
The dash cam can create a Wi-Fi hotspot to share its 4G internet connection with other devices.
- Enable the Wi-Fi hotspot feature in the device settings or via the CloudSpirit app.
- Connect your smartphone, tablet, or laptop to the dash cam's Wi-Fi network (2.4GHz, 802.11b/g/n).

4.6 Loop Recording
Loop recording ensures continuous video capture by overwriting the oldest files when the memory card is full. This prevents the recording from stopping due to insufficient storage.

4.7 G-Sensor
The 3-axis G-sensor detects sudden acceleration, braking, or collisions. When such an event occurs, the sensor triggers the dash cam to automatically lock and protect the current video file, preventing it from being overwritten by loop recording.
4.8 Night Vision
The dash cam is equipped with advanced night vision technology to ensure clear video recording even in low-light conditions or at night.

5. Maintenance
5.1 Cleaning
- Regularly clean the camera lenses with a soft, lint-free cloth to ensure clear video quality.
- Wipe the device body with a dry cloth. Do not use liquid cleaners or solvents.
5.2 MicroSD Card Management
- Format the microSD card periodically (e.g., once a month) to maintain optimal performance and prevent data corruption.
- Back up important video files to a computer or cloud storage before formatting.
5.3 Firmware Updates
Check the official Bluavido website or the CloudSpirit app for available firmware updates. Keeping your device's firmware up-to-date ensures optimal performance and access to new features.
6. Troubleshooting
- Device not powering on: Check power connections, ensure the car charger or OBD cable is properly inserted, and verify the vehicle's power outlet is functional.
