3. Setting Date and Time
To ensure accurate timestamps on your recordings, you must manually set the date and time. This is done by creating a text file on the Micro SD card:
- Insert the Micro SD card into the provided USB card reader and connect it to your computer.
- Create a new text file (e.g., using Notepad on Windows or TextEdit on Mac) in the root directory of the Micro SD card.
- Name the file time.txt.
- Open time.txt and enter the current date and time in the format: YYYY-MM-DD HH:MM:SS (e.g., 2025-08-25 14:30:00).
- Save and close the file.
- Safely eject the Micro SD card from your computer and reinsert it into the power bank camera.
- Power on the device. The date and time will be updated automatically. The time.txt file will be automatically deleted after the update.
Operating Instructions
Power On/Off
Press and hold the power button (usually located near the USB ports) for a few seconds until the display lights up, indicating the device is powered on. To power off, press and hold the power button again until the display turns off.
Switching Recording Modes (L/M)
The device supports two recording modes: Loop Recording (L) and Motion Detection (M). To switch between these modes, locate the small toggle switch next to the Micro SD card slot, under the rubber flap. Slide the switch to 'L' for continuous loop recording or 'M' for motion-activated recording.
- Loop Recording (L): In this mode, the camera records continuously in 20-minute segments. When the SD card is full, the oldest files will be automatically overwritten to make space for new recordings.
- Motion Detection (M): When movement is detected within the camera's field of view, the device will automatically begin recording. Recordings in this mode are typically 20 minutes in length. Note that this camera does not record audio.

2K HD Video and Image Capture
The camera captures video and still images in 2K resolution (2560x1440p), providing clear and detailed footage. Recordings are saved as MP4 files on the Micro SD card.
Night Vision Function
The SN-10000 features upgraded night vision capabilities for clear recording in low-light or dark environments. To activate night vision, refer to the specific instructions in the included physical manual, as it requires manual setup for optimal performance. The camera utilizes 10 IR LEDs for illumination.

Gravity Sensor
The integrated gravity sensor automatically adjusts the video orientation. If the camera is flipped 180 degrees during recording, the video will automatically switch to the correct upright orientation, eliminating the need for manual settings or post-production adjustments.

Viewing Recordings
To view recorded footage, remove the Micro SD card from the device. Insert the Micro SD card into the provided USB card reader and connect the card reader to a computer. The video files (MP4 format) can then be accessed and played using standard media player software.
Maintenance
- Cleaning: Use a soft, dry cloth to clean the exterior of the device. Do not use liquid cleaners or aerosols.

- Battery Care: For optimal battery life, avoid fully discharging the device frequently. Charge it regularly, even if not in active use.

Troubleshooting
| Issue | Possible Cause / Solution |
|---|---|
