3.3 Power Connection
Connect the car power adapter to the dash cam and plug it into your vehicle's power outlet (e.g., cigarette lighter socket). The system is designed to connect directly to the vehicle's power source for stable and continuous operation. Ensure the connection is secure.
3.4 SD Card Insertion
The system comes with a 128GB SD card. Insert the SD card into the designated slot on the dash cam. Ensure it is inserted correctly until it clicks into place. The dash cam will automatically begin recording once powered on and the card is detected.
4. Operating Instructions
4.1 Basic Recording
Once powered on, the dash cam automatically begins 4-channel 1080P recording. The system captures video from the front, rear, left, and right sides of your vehicle simultaneously.

4.2 Loop Recording
The dash cam utilizes loop recording. When the memory card is full, the system automatically overwrites the oldest unprotected files to ensure continuous recording. This eliminates the need for manual deletion of old footage.

4.3 G-Sensor Emergency Video Protection
The built-in G-sensor detects sudden impacts or collisions. When triggered, it automatically locks the current video segment, saving it to a dedicated protected folder. This prevents the emergency footage from being overwritten by loop recording.
4.4 Night Vision and Infrared Cabin Recording
Equipped with advanced night vision technology, the dash cam captures clear road details even in low-light conditions. Additionally, built-in infrared lights enable sharp recording of the vehicle interior, even in total darkness, which is beneficial for monitoring passengers or internal activities.
4.5 24-Hour Parking Surveillance
When the vehicle is parked, the parking monitor function is automatically activated. Utilizing its high-sensitivity G-sensor, the dash cam will begin recording if it detects motion or an impact, providing surveillance even when you are away from your vehicle.

4.6 HDR Function
The High Dynamic Range (HDR) function enhances video quality by optimizing exposure in varying light conditions. This results in clearer footage with better detail in both bright and dark areas, preventing overexposure or underexposure.

4.7 Reversing Assistance
When the vehicle is shifted into reverse gear, the dash cam system automatically switches to a full-screen reflection of the rear camera view. This feature assists in safe reversing by providing a clear view of the area behind the vehicle.

5. Maintenance
5.1 SD Card Management
While loop recording manages storage, it is recommended to periodically format the SD card (e.g., once a month) to maintain optimal performance and prevent potential data corruption. Always back up important footage before formatting. If the dash cam displays a "Format card" prompt frequently, it may indicate a need for formatting or a potential issue with the SD card itself.
5.2 Cleaning
Gently clean the dash cam lenses and screen with a soft, lint-free cloth. Avoid using abrasive cleaners or solvents that could damage the surfaces.
6. Troubleshooting
- "No Card" or "Format card" Error: Ensure the SD card is correctly inserted. If the error persists, try reformatting the card via the dash cam's menu. If the issue continues, the SD card may be faulty and require replacement.
- Poor Video Quality: Verify that the recording resolution is set to 1080P in the settings. Clean the camera lenses to remove any dirt or smudges. Ensure the protective film has been removed from the lenses.
- Dash Cam Not Powering On/Charging: Check all power connections, including the car power adapter and the vehicle's power outlet. Ensure the vehicle's power outlet is functional.
- Rear Camera Not Displaying: Check the cable connection between the rear camera and the main unit. Ensure the cable is not damaged or pinched.
- Missing Mounting Accessories: If any essential mounting parts, such as a suction cup mount, are missing, please contact customer support for assistance.
- Incorrect Power Plug: The product may come with a power plug designed for specific regions. If the included plug does not fit your vehicle's power outlet, an appropriate adapter may be required.
