3.4 Loop Recording & G-Sensor
Seamless loop recording overwrites the oldest videos when the memory card is full (except locked files). The G-sensor automatically locks the current video upon detecting shaking or collision, preventing it from being overwritten and saving it in the event folder for accident evidence.

When your car is parked and a collision or theft is detected, the dash cam will automatically switch on and record for about ten seconds and lock the video. Continuous 24-hour recording requires a separate hardwire kit for power.
3.6 Reverse Camera with Parking Aid
The included 1080P rear camera provides a clear rear view and offers a reversing aid line to assist with safe parking. Connect the red wire of the rear camera to the positive pole of the reversing light for this feature.

4. Setup & Installation
4.1 Front Dash Cam Installation
The dash cam can be mounted using either the suction cup mount or the sticky mount. Choose a location on your windshield that does not obstruct your view. Ensure the windshield is clean and dry before applying the mount.
- Suction Cup Mount: Attach the suction cup to the dash cam. Press the suction cup firmly against the windshield and flip the lever to secure it.

The rear camera comes with a 19-foot cable, suitable for most vehicles. Before permanent installation, test the rear camera by connecting it to the front dash cam and ensuring it displays correctly.

- Insert the Micro SD card into the TF port on the side of the dash cam until it clicks into place.
- Before first use, it is highly recommended to format the memory card within the dash cam's settings to ensure compatibility and proper function.

- Dash Cam Not Working: Try restoring factory settings. If the issue persists, gently poke the reset hole with a card pin (refer to manual for location).
- WiFi Connection Unsuccessful: Ensure WiFi is enabled on the dash cam. On your phone, turn off auto-join for other networks before connecting to the dash cam's WiFi. If the app shows a black loading screen, your phone may have disconnected from the dash cam's WiFi; try re-linking.
- Rear Camera Not Displaying: Check all cable connections to ensure they are securely plugged in. You can switch the display of front and rear views by long-pressing the UP button on the dash cam.
- Screen Turning On/Off While Driving: For daily driving, it is recommended to turn off motion detection and screensavers in the settings to prevent the camera from frequently turning on and off. These features are primarily for parking mode.
