3. Operating Instructions
3.1 Basic Operation
- Power On/Off: The dash cam typically powers on automatically with the car ignition. To manually power on/off, press and hold the power button.
- Recording: Once powered on, the dash cam will automatically start continuous loop recording. A red dot or indicator on the screen confirms recording is active.
- Screen: The 2.7-inch LCD screen displays the live view, recording status, and menu options.

3.2 Recording Modes
- Ordinary Recording: Records continuously in segments (e.g., 1, 3, or 5 minutes). When the memory card is full, the oldest unlocked files are overwritten. Supports 1296P at 30fps or 1080P at 60/30fps.
- Emergency Recording (G-Sensor): In the event of a collision or sudden braking, the built-in 3-Axis G-Sensor automatically detects the event and saves the current recording segment to a protected folder, preventing it from being overwritten. You can customize G-sensor sensitivity (low, medium, high) in the settings.
3.3 Advanced Driver Assistance Systems (ADAS)
The ADAS feature provides real-time intelligent warnings to enhance driving safety:
- Lane Departure Warning: Alerts you if the vehicle drifts out of its lane.
- Forward Collision Warning: Warns you of potential frontal collisions.
3.4 Voice Control
The dash cam supports voice commands for hands-free operation. Currently, it supports commands for video recording and emergency image capture. Refer to the on-screen prompts or the full user manual for specific commands.
3.5 Wi-Fi Connectivity
The dash cam features built-in Wi-Fi (single band 2.4GHz, 802.11n standard) for connecting to your smartphone. This allows you to view live footage, playback recorded videos, download files, and adjust settings via a dedicated mobile application (compatible with Android and iOS).

4. Maintenance
4.1 Cleaning the Lens and Screen
- Use a soft, lint-free cloth to gently wipe the camera lens and screen.

- Avoid using abrasive cleaners or solvents that could damage the lens coating or screen.
4.2 MicroSD Card Care
- Regularly format the microSD card (at least once a month) to maintain optimal performance and prevent data corruption. This can usually be done through the dash cam's settings menu.
- Replace the microSD card if you notice frequent errors or degraded performance.
4.3 General Care
- Avoid exposing the dash cam to extreme temperatures for prolonged periods.
- Do not attempt to disassemble or repair the device yourself, as this will void the warranty.
