4. Setup
4.1 Inserting the MicroSD Card
- Ensure the dash cam is powered off.
- Locate the MicroSD card slot on the side of the device.
- Insert a Class 10 or higher MicroSD card (up to 32GB, not included) into the slot until it clicks into place.
- To remove, gently push the card in until it clicks, then release, and it will eject.
Note: Format the MicroSD card within the dash cam's settings menu before first use and periodically thereafter to ensure optimal performance.
4.2 Mounting the Dash Cam
- Clean the chosen area on your windshield, preferably near the rearview mirror, to ensure a strong adhesive bond for the mounting bracket.
- Attach the adhesive mount to the windshield, pressing firmly for at least 30 seconds.
- Connect the dash cam to the magnetic mounting bracket. The magnetic connection allows for easy attachment and detachment of the camera unit.
- Adjust the camera lens to ensure it captures the desired view of the road ahead.
4.3 Power Connection
- Connect the provided power cable to the dash cam's power input port.
- Plug the other end of the power cable into your vehicle's 12V power outlet (cigarette lighter socket).
- The dash cam will typically power on automatically when the vehicle's ignition is turned on and begin recording.
4.4 Initial Settings
Upon first use or after a reset, you may need to set the date and time. Use the dash cam's buttons to navigate the menu on the 1.2-inch LCD screen:
- Access the menu settings.
- Navigate to "Date/Time" and adjust as necessary.
- Confirm settings to save.
5. Operating the Dash Cam
5.1 Basic Recording
Once powered on, the D28RS dash cam will automatically begin recording. A red indicator light or icon on the screen will confirm recording is active. Video files are saved to the MicroSD card in segments.
5.2 Loop Recording
The dash cam features seamless loop recording. When the MicroSD card reaches its full capacity, the oldest unlocked video files will be automatically overwritten by new recordings. This ensures continuous recording without manual intervention.

5.3 G-Sensor Function
The built-in G-Sensor detects sudden impacts or collisions. When an impact is detected, the dash cam automatically locks the current video file, preventing it from being overwritten by loop recording. These locked files are stored in a separate folder on the MicroSD card.

5.4 Parking Monitor
When the Parking Monitor function is enabled in the settings, the dash cam will continue to monitor your vehicle even when it is turned off and parked. If motion is detected in front of the camera or a vibration is sensed (via the G-Sensor), the dash cam will automatically turn on and record a short video segment.
