The dash cam comes with both a suction cup mount and an adhesive mount. Choose the one that best suits your needs.
- Clean the windshield area where you intend to mount the dash cam. Ensure it is free of dust and grease.
- Align the bracket of your chosen mount with the connection port on the top of the dash cam. Push it in firmly until you hear a "click," indicating it is securely locked.
- For the suction cup mount, press the suction cup firmly against the windshield and flip the lever to secure it. For the adhesive mount, peel off the protective film and firmly press the mount onto the desired location on the windshield.

Note: Ensure the dash cam is positioned where it does not obstruct your view of the road. The interior camera can be rotated 180° for optimal cabin recording.

5.1 Formatting the SD Card
It is crucial to format the included 64GB Micro SD card before first use and periodically thereafter to ensure optimal recording performance and prevent data corruption.
- Insert the 64GB Micro SD card into the designated slot on the dash cam.
- Navigate to the "Setup" menu.
- Select "Format" and confirm the action. This will erase all data on the card.

6. Operating Modes and Features
The LAMTTO Dual Dash Cam offers several intelligent features to enhance your driving and parking security.
6.1 Loop Recording
This feature ensures continuous recording by overwriting the oldest unlocked video files when the memory card reaches its capacity. This eliminates the need to manually clear the card.

6.2 G-Sensor (Accident Lock)
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. This ensures critical accident footage is preserved.

6.3 Parking Monitor (24/7 Hours)
When enabled, the parking monitor feature allows the dash cam to automatically start recording if it detects a collision or significant movement while your vehicle is parked. This provides surveillance and helps capture evidence of hit-and-runs or vandalism.


6.4 Infrared Night Vision
The interior camera is equipped with 4 infrared lights, significantly enhancing its ability to capture clear and detailed footage of passengers and the cabin environment, even in complete darkness.

7. Maintenance
To ensure the longevity and optimal performance of your dash cam, regular maintenance is recommended.
- Cleaning: Use a soft, dry cloth to clean the camera lenses and screen. Avoid using abrasive cleaners or solvents.
- SD Card Care: Format the SD card regularly (e.g., once a month) to prevent data fragmentation and ensure smooth recording. Back up any important files before formatting.
- Temperature: Avoid exposing the dash cam to extreme temperatures for prolonged periods, as this can affect battery life and component integrity.
- Firmware Updates: Check the manufacturer's website periodically for any available firmware updates to improve performance or add new features.
