- Turn Off Engine: Ensure the car engine is turned off before proceeding with installation.
- Insert TF Card: Insert a high-speed TF card (Class 10 or above, 4 GB to 256 GB capacity) into the dash cam's card slot. Refer to specifications for details.
- Fix Dash Cam: Fix the dash cam on the car's front windshield using the provided bracket.
- Connect Power: Insert the car charger into the car's cigarette lighter socket.
Note: When routing the cable, it can be laid along the edge of the car door frame and under the car carpet for a neat installation.
- Install Rear Camera (Optional): Install the rear camera at the rear of the vehicle. Pay attention to the up and down direction during installation. The cable can be laid along the top edge of the vehicle.
Note: There are two installation methods for the rear camera:
- Attach it to the top of the car's rear glass (DIY installation). This method does not support reverse viewing function; only real-time video recording of the rear is available.
- Ask professional installers to install it above the license plate frame. The camera needs to be connected to the reverse light power supply to enable the reverse viewing function.
- Adjust Lens Position: Adjust the position of the lens to achieve the best shooting perspective.
- Start Engine: Start the engine and check if the device is working normally.
5. Operation
5.1. Basic Recording
Once powered on, the dash cam will automatically begin recording. Use the Power Button to start/stop recording manually if needed.
5.2. Loop Recording
The device supports loop recording, automatically overwriting the oldest unlocked video files when the memory card is full. This ensures continuous recording without manual intervention.
5.3. G-Sensor (Gravity Sensor)
The built-in G-Sensor detects sudden movements or collisions. In the event of an impact, it automatically locks the current video segment to prevent it from being overwritten by loop recording, ensuring critical footage is preserved.
5.4. Super Night Vision
The dash cam features Super Night Vision with WDR (Wide Dynamic Range) on the front camera and HDR (High Dynamic Range) on the rear camera, a 6-Glass Lens, and F/1.8 Aperture to provide clear video recordings even in low-light conditions.
5.5. Advanced Driver Assistance System (ADAS) & Blind Spot Detection (BSD)
The dash cam may include ADAS features such as Front Vehicle Movement, Pedestrian Collision Warning, Headway Monitoring, and Lane Departure Alerts. Blind Spot Detection (BSD) provides real-time voice alerts to help avoid accidents by detecting surroundings.
6. Wi-Fi Connection and APP Control
This feature is only available on devices with Wi-Fi functionality. If your device does not have Wi-Fi capability, please ignore this section.
6.1. Download Viidure APP
Before connecting to the dash cam via your phone, you need to install the "Viidure APP".
- Method 1: Scan the QR code below to download the Viidure APP.
- Method 2: Search for "Viidure" in the Android App Store or iOS App Store and download it.
6.2. Connect to the Dash Cam
- Step 1: Enter the video recording mode on the dash cam. Then, press the Up Button. The dash cam will automatically enter Wi-Fi connection mode, displaying the SSID and WPA2 password on its screen (e.g., SSID: ActionCam 60def4e, WPA2: 12345678).
- Step 2: Open the Viidure APP on your phone. Follow the on-screen prompts to add a camera. You may need to grant location permissions.
- Step 3: Go to your mobile phone's Wi-Fi settings, find the Wi-Fi SSID corresponding to your dash cam (e.g., "ActionCam 60def4e"), and enter the Wi-Fi password (e.g., "12345678") to connect.
- Step 4: Return to the Viidure APP. You can now view recorded videos and adjust dash cam settings.
6.3. View Recorded Videos
In the Viidure APP, click "Camera File" to view recorded videos. Note that videos played on the mobile phone are compressed. For original high-definition quality, download the video to your phone first.
6.4. Download Videos

6.5. Set up Dash Cam through APP
Click "Camera Settings" on the bottom right of the APP page to access various settings.
6.6. Return to Key Operation
If the dash cam screen shows the Wi-Fi connection prompt and you wish to return to the recorder's recording screen, close the Viidure APP and simultaneously press the Up Button on the dash cam. Wait for 3 seconds for the device to restore.
7. 24-Hour Parking Monitoring (Optional)
For 24-hour parking monitoring, a dedicated "Buck Line" accessory is required to replace the standard car charger. The Buck Line draws power directly from the car battery or ACC, allowing the DVR to record even when the car is off.
Note: Due to varying car battery and ACC interfaces, professional installation of the Buck Line is recommended.
The Buck Line enables features such as 24-hour parking monitoring, video time lapse, and time lapse power off. The time-lapse video function requires the Buck Line with delay function.
8. GPS Tracking (Optional)
If your dash cam model includes GPS functionality, it supports high-precision GPS signals for accurate recording of vehicle location and speed data.
8.1. Installation and Use of GPS
- Connect the GPS module to the DVR.
- Install the DVR on the car and start recording. Drive outdoors for a certain distance. The GPS module will automatically capture satellite signals, and the DVR will record video with GPS driving track data.
8.2. Video Playback of GPS Tracks
To view GPS track information along with your recorded videos, you need to use a dedicated video player on your computer:
- Install the "Hit GPS Player" software on your computer. Download it from: https://pcgps.ce2ce.com/hit/hitplayer.html
- Open the recorded DVR video files (which contain GPS track information) using "Hit GPS Player" to play back the GPS driving track.

10. Troubleshooting
Most problems are related to the memory card, and a small number are related to the power cable.
| Problem | Solution |
|---|---|
| The device shows the prompt "File Error" | Go to Settings Menu -> Restore Factory Settings and format the memory card. This problem is usually related to the TF card. |
| Horizontal stripe interference appears on the screen | Please select the correct power supply frequency of 50HZ (PAL). |
| How to correctly enable the 24-hour parking monitoring function | Do not enable it during normal driving, as it may easily cause automatic shutdown or crash. It only needs to be enabled after parking. Please configure a step-down cable (Buck Line) or a mobile power supply. |
| The image captured at night is not clear enough | The dash cam relies on strong external light sources (such as street lights and car lights) for shooting, which is common in the industry. |
| The device always reverts to the default date and time | Charge the device fully when it is turned off. You can use a car charger or a mobile power supply to recharge it. |
| What causes missing seconds in video files | Turn off motion detection recording or turn on the loop recording function. For self-prepared memory cards, ensure you use genuine Class 10 high-speed cards. |
| Why does the device shut down automatically suddenly during recording | Turn off the parking monitoring function first. Automatic shutdown may also occur if the temperature of the use environment exceeds 158°F (70°C). |
11. User Tips
- Memory Card Quality: Always use a high-quality, genuine Class 10 (or higher) TF card to prevent "File Error" messages and ensure reliable recording. Many issues stem from incompatible or low-quality memory cards.
- Language Settings: The dash cam supports multiple languages, including English, Chinese, Korean, Japanese, Russian, Arabic, Czech, Dutch, French, German, Hebrew, Indonesian, Italian, Polish, Spanish, Thai, Turkish, and Vietnamese. If your device's menu is not in your preferred language, navigate to the 'Language' setting in the system menu to change it.
- Parking Monitor Activation: Remember to only enable the 24-hour parking monitoring function when the vehicle is parked. Activating it during driving can lead to unexpected shutdowns or crashes.
- GPS Player: For detailed GPS track playback, download and install the "Hit GPS Player" on your computer from the provided link in the GPS Tracking section.
