Setup
1. Memory Card Preparation
- Insert the included 64GB memory card into the dashcam's designated slot.
- Before first use, it is crucial to format the memory card within the dashcam's settings menu. This ensures compatibility and optimal performance. Refer to the "Operation" section for menu navigation.
2. Mounting the Dashcam
- Clean the chosen area on your windshield thoroughly.
- Attach the suction cup mount to the main dashcam unit.
- Securely mount the dashcam on the windshield, ensuring it does not obstruct your view. Position it centrally for optimal front camera coverage.
- Adjust the angle of the main unit and the side cameras to capture the desired views (front, left interior, right interior).
3. Connecting Power
- Connect the car power adapter to the dashcam's power input port.
- Plug the other end of the car power adapter into your vehicle's 12V power outlet (cigarette lighter socket).
- Route the power cable neatly along the windshield and dashboard edges to avoid interference with driving.
4. Rear Camera Installation
- Identify a suitable mounting location for the rear camera, typically on the rear windshield or near the license plate.
- Connect the rear camera cable to the main dashcam unit.
- Route the rear camera cable discreetly through the vehicle's interior trim to the chosen mounting location.
- Secure the rear camera in place and adjust its angle for optimal rear view coverage.
Operation
1. Basic Recording
Once powered on, the dashcam will automatically begin recording. The system records simultaneously from all four cameras (front, rear, left interior, right interior) in 1080P resolution.

Figure 4: Four-Channel Simultaneous Recording. This image demonstrates the dashcam's ability to display and record footage from all four cameras concurrently, showing views from the front, rear, and both interior sides of the vehicle.
2. Loop Recording
The dashcam utilizes loop recording. When the memory card is full, the system automatically overwrites the oldest unprotected files to ensure continuous recording. This feature prevents the memory card from running out of space.

Figure 5: Loop Recording Function. This graphic depicts the circular nature of loop recording, where the dashcam continuously records and, once the memory card capacity is reached, automatically replaces the oldest video files with new ones.
3. G-Sensor (Collision Detection)
The built-in G-sensor detects sudden impacts or collisions. When triggered, it automatically locks the current video segment, preventing it from being overwritten by loop recording. These locked files are stored in a separate folder on the memory card.
4. Enhanced Night Vision and HDR
The interior and rear cameras are equipped with IR (Infrared) technology for clear recording in low-light or dark conditions. The system also features HDR (High Dynamic Range) functionality to improve image clarity in varying light environments, such as bright sunlight or shadows.

Figure 6: Super Night Vision Performance. This image compares three scenarios: a dark road, the same road with HDR enabled, and a bright road, highlighting how the dashcam's night vision and HDR features enhance video clarity in low-light conditions.

Figure 7: HDR Functionality. Similar to night vision, this image illustrates the effect of HDR by comparing a dark scene, an HDR-enabled scene, and a bright scene, showing improved detail and exposure balance in challenging lighting.
5. 24-Hour Parking Surveillance
When the vehicle is parked, the parking monitor feature is automatically activated. Utilizing its high-sensitivity G-sensor, the dashcam will begin recording if it detects motion or an impact, providing surveillance even when the vehicle is off.

Figure 8: Parking Surveillance. This graphic shows a car protected by a hexagonal shield, with smaller images depicting scenarios like a person attempting to break into a car and a car being bumped, illustrating the dashcam's 24-hour parking surveillance capabilities.
6. Reversing Assist
When the vehicle is shifted into reverse gear, the dashcam automatically switches its display to a full-screen view of the rear camera, often with parking guidelines, to assist with safe reversing maneuvers.

Figure 9: Reversing Assist Feature. This image shows a car reversing in a parking lot, with the dashcam display showing a full-screen view from the rear camera, complete with overlaid parking guidelines to aid the driver.
7. Control Methods
The dashcam supports control via a dedicated mobile application and voice commands. Refer to the app's instructions for detailed setup and usage of app control. Voice commands allow for hands-free operation of key functions.
Maintenance
1. Cleaning the Dashcam
- Gently wipe the camera lenses with a soft, lint-free cloth to remove dust or smudges. Avoid abrasive materials.
- Clean the main unit's screen and body with a slightly damp cloth. Do not use harsh chemicals or solvents.
2. Memory Card Management
- Regularly format the memory card (e.g., once a month) through the dashcam's settings menu to ensure optimal performance and prevent data corruption.
- Back up important video files to a computer or external storage before formatting the card.
- If the memory card shows signs of degradation or errors, replace it with a new, high-quality card.
