6. Features Explained
6.1. WDR Technology

Figure 3: WDR Technology in action. This image demonstrates how Wide Dynamic Range (WDR) technology improves image clarity by balancing exposure in scenes with both very bright and very dark areas, preventing overexposure or underexposure.
WDR (Wide Dynamic Range) technology enhances the clarity of images in various light environments. It helps to balance exposure, ensuring that both bright and dark areas of the footage are clearly visible, which is crucial for capturing details in challenging lighting conditions.
6.2. Wide Recording Angle

Figure 4: Wide Recording Angles and Key Features. This image illustrates the 140° front and 120° inside recording angles, highlighting the comprehensive coverage. It also visually represents seamless loop recording and practical recording for security events.
The front camera offers a 140° wide recording angle, while the inside camera provides a 120° angle. This wide coverage ensures that simultaneous front, inside, and rear recordings capture a broad view, minimizing blind spots and ensuring no critical events are missed.
6.3. Seamless Loop Recording
When the Micro SD card reaches its storage limit, the dash cam automatically overwrites the oldest footage with new recordings. This ensures continuous recording without the need for manual deletion of old files. Important footage locked by the G-Sensor will not be overwritten.
6.4. Practical Recording (Parking Monitor & Motion Detection)
The dash cam provides all-round recording capabilities to capture important events even when parked. The Parking Monitor feature detects impacts or motion around the vehicle, automatically starting recording to document potential incidents like theft or collisions. Motion Detection also triggers recording when movement is sensed in the camera's field of view.
6.5. HD 6-Glass Lens

The dash camera is equipped with an HD 6-glass optical lens designed to capture true colors and high-quality images. The multi-layered lens structure helps to increase sharpness, improve light penetration, correct light, block clutter, and ensure accurate color reproduction.
7. Maintenance
- Cleaning: Use a soft, dry cloth to clean the camera lenses and screen. Avoid using abrasive cleaners or solvents.
- SD Card Management: Regularly format your Micro SD card (at least once a month) to maintain optimal performance and prevent data corruption. Back up any important footage before formatting.
- Temperature: Avoid exposing the device to extreme temperatures, which can affect battery life and performance.
8. Troubleshooting
- Device Crashes/Accidental Operation: If the recorder crashes or experiences an abnormal fault, press the RESET button to shut down the device. Then, press the OK button to reboot the device.
- Recording Issues: Ensure a Class 10 or higher Micro SD card is used and that it is formatted correctly. Check if loop recording is enabled.
- Power Issues: Always connect the dash cam to external power (cigarette charger) while in use. The inbuilt battery is primarily for saving files in emergencies, not for continuous operation.
- Poor Image Quality: Clean the camera lenses. Ensure WDR is enabled for challenging light conditions.
