4. Setup & Installation
4.1 Initial Setup
- Turn off the car engine.
- Insert the TF card: Insert a high-speed Micro SD card (Class 10 or above, minimum 32GB, maximum 512GB) into the card slot of the recorder.
- Fix the recorder: Securely fix the dash cam on the car windshield.
4.2 Power Supply Connection
The dash cam requires a 12V power supply. A 24V power supply will damage the motherboard unless a 24V to 12V converter is used.
- Option 1: Car Charger (Standard)
- Insert the car charger into the car's cigarette lighter.
- Connect the charging extension cable from the car charger to the device's USB port.
- The device will start automatically when the car engine launches.
- Option 2: Hardwire Kit (Buck Line) for 24H Parking Monitoring (Optional, purchase separately)
The parking monitoring mode requires a three-core buck line connection. Ordinary car chargers cannot trigger this function.

Figure 3: Buck Line Wiring Diagram. Connect GND to car ground, ACC to switched power, BAT to constant power. - Connect the negative pole (black wire) of the Hardwire Kit to the ground of the car fuse box.
- For continuous 24-hour parking monitoring, connect the positive pole (red wire) of the Hardwire Kit to the BAT (constant power) interface of the car fuse box.
- If you want monitoring to stop when the car is off, connect the positive pole (red wire) of the Hardwire Kit to the ACC (switched power) interface of the car fuse box.
- When wiring, lay the charging extension cable along the edge of the car windshield.
4.3 Rear Camera Installation (Optional)
The rear camera can be installed on the rear windshield to record the rear view or on the front windshield to record the inside view of the car.

- Install the rear camera at the rear of the vehicle, paying attention to the direction. Route the wiring along the roof of the vehicle.
- Connect the rear plug to the rear camera interface (AV port) of the recorder.
- To enable the auto-reversing function (displaying parking lines when in reverse gear), connect the rear camera's red cable wire to your car's reverse lamp positive pole (+). If this function is not desired, you can ignore the red wire.
- Adjust the lens position to ensure it is level with the ground.
4.4 GPS Module Connection (Optional)

The GPS module connects to the dash cam, which then receives power from the car charger or hardwire kit. When connecting the GPS module for the first time, allow time for it to locate. The GPS icon on the screen will change from red to green upon successful positioning.
4.5 Final Check
Start the car engine and check if the dash cam is installed correctly. The system working indicator light should be on. When the device starts recording, the video indicator light will flash, indicating successful installation and operation.

5.4.1 PC Version GPS Player
For Windows 7/8/10 (64-bit or 32-bit), download the GPS track map player from https://pcgps.ce2ce.com/hit/hitplayer.html. For Mac OS, search "HIT GPS Player" in the App Store. After installation, open video files or drag them to the player bar to display the GPS track.
5.4.2 Mobile Version GPS Display
When GPS tracking is successful, the mobile app will display speed, direction, and coordinates.
5.5 Parking Monitoring (Optional)
If a three-core buck line is installed, the parking monitoring function can be activated. This feature allows time-lapse recording for 6, 12, 24, or 48 hours after triggering. The dash cam will automatically shut down if the car battery voltage drops below 11.7V to prevent draining the car battery.
5.6 Loop Recording
When this feature is enabled, the dash cam continuously records. If the memory card becomes full, the oldest video files will be automatically overwritten by new recordings. Videos locked by the G-Sensor or parking monitoring will not be overwritten.
5.7 G-Sensor
The G-Sensor detects sudden impacts or emergencies. When triggered, the recorder immediately locks the current video file to protect it from being overwritten.
5.8 WDR Dynamic Light Processing
Wide Dynamic Range (WDR) technology helps eliminate glare and dimming, providing clearer video footage in challenging lighting conditions.
5.9 Video Review and Download
You can review recorded videos and download files directly through the Viidure app. Downloaded files are automatically saved to your phone's album.
6. Maintenance
- TF Card Management: Regularly format your TF card to ensure optimal performance and prevent file corruption. If you encounter errors when replaying pictures or videos, reformat the card using the Car DVR's "Format" function.
- Lens Cleaning: If images appear foggy, check the lens for dirt or fingerprints. Before shooting, gently wipe the lens with lens paper.
- Device Integrity: Do not attempt to dismantle the machine yourself, as this may void the warranty.
7. Troubleshooting (FAQ)
If you encounter problems under normal operating conditions, refer to the solutions below:
- Cannot take photos or video: Check if the TF card has enough space and is not locked. Ensure you are using a Class 10 high-speed TF card.
- Recording automatically stops: This can happen due to large high-definition video data. Ensure you are using an SDHC compatible, high-speed TF card (Class 10 identity).
- "File" error when replaying pictures/videos: This indicates incomplete files or memory card data issues. Use the Car DVR's "Format" function to reformat the card.
- Image is foggy: Check the lens for dirt or fingerprints. Wipe the lens with lens paper before recording.
- Recorder does not work: Press the reset key (if available) with a sharp object, or press the power button 5 times continuously, then restart the device to restore normal operation.
- Cannot connect to the product via mobile phone:
- Ensure your mobile phone is not connected to other Wi-Fi hotspots. The app can only connect when your phone's Wi-Fi is directly connected to the recorder's Wi-Fi.
- If the real-time picture is stuck, it may be due to a weak Wi-Fi signal (e.g., phone too far from the recorder) or interference from too many other Wi-Fi signals in the vicinity.
- Preview speed in the album is very slow: This may occur if there are too many video files on the TF card, causing timeouts when retrieving file information. Regularly format your TF card.
- Computer cannot play video recordings smoothly: The product uses H.264 compression (TS/MOV/MP4 format). Many built-in Windows media players may not support H.264 encoding or may struggle with playback. It is recommended to download professional video playback software (e.g., PotPlayer).
- Wi-Fi password forgotten: Reset the device to factory settings using the power button reset method (press 5 times continuously) to clear the Wi-Fi password.
- Rear camera not working: Ensure the rear camera is properly connected to the AV port and its wiring is correct. If the issue persists, the camera unit may be faulty.
- GPS module not included/working: The GPS module is optional and may not be included in all packages. If purchased, ensure it is correctly connected and allowed time to acquire a signal (GPS icon turns green).
- Dash cam heats up and stops: Ensure you are using the standard car charger and not a data cable. Overheating can be caused by improper power supply or a faulty unit.
- Parking mode stops recording after a few minutes: Ensure the hardwire kit is correctly installed and connected to a constant power source (BAT) in the fuse box. Check the low voltage protection setting (11.7V).
8. User Tips
- Memory Card: Always use a high-quality Class 10 Micro SD card (32GB-512GB) for reliable recording, especially for 4K video. Regularly format the card to prevent data corruption and ensure smooth operation.
- Power Supply: Strictly adhere to using the provided car charger or a compatible hardwire kit. Avoid using generic USB data cables for power.
- Rear Camera Installation: If you need the auto-reversing function, ensure the red wire of the rear camera is connected to the car's reverse light positive pole. If not, you can leave it disconnected. Professional installation is recommended for rear cameras.
- Wi-Fi Connectivity: For stable app connection, ensure your phone is close to the dash cam and not connected to other Wi-Fi networks.
- GPS Tracking: Allow the GPS module sufficient time to acquire a signal for accurate location and speed data.
- Parking Monitoring: For 24-hour parking monitoring, a hardwire kit is essential. Ensure it's correctly wired to the car's fuse box (BAT for constant power).
- Video Playback: If experiencing issues playing videos on a computer, try using a dedicated media player like VLC or PotPlayer, as some default players may not support the H.264 codec.
