5. Setup Instructions
- Prepare the MicroSD Card:
The camera comes with a 64GB MicroSD card. Before first use, or if you encounter recording issues, it is recommended to format the MicroSD card. Use the included USB card reader to connect the card to your computer. Access Disk Utility (Mac) or Disk Management (Windows) to format the card to MS-DOS (FAT32) for 32GB or smaller, or ExFAT for 64GB or larger. Ensure all data is backed up before formatting as it will be erased.

- Insert MicroSD Card:
Carefully remove the front cover of the camera. Insert the formatted MicroSD card into the designated card slot until it clicks into place. Ensure it is inserted correctly to avoid malfunction.
- Select Recording Mode:
Locate the mode switch on the camera (refer to Product Diagram).
- Slide the switch to "C" for Loop Recording Mode (Blue LED flashes three times).
- Slide the switch to "M" for Motion Detection Mode (Red LED flashes twice).
- Power On:
Plug the camera into a standard 110V-240V AC power outlet. The camera will automatically begin recording according to the selected mode. The LED indicator will blink briefly to confirm recording has started and then turn off to remain discreet.

6. Operating Instructions
6.1 Recording Modes
- Loop Recording (C Mode): The camera records continuously. When the MicroSD card is full, the oldest files will be automatically overwritten by new recordings.
- Motion Detection (M Mode): The camera records only when motion is detected within its field of view. This mode conserves storage space and is ideal for capturing specific events.
6.2 Viewing Recorded Footage
- Unplug the camera from the power outlet.
- Carefully remove the front cover and eject the MicroSD card from its slot.
- Insert the MicroSD card into the provided USB card reader.
- Plug the USB card reader into your computer's USB port.
- Access the "VIDEO" folder on the MicroSD card to view your recorded AVI files.
The video files will have a timestamp in the bottom left corner. This timestamp can be adjusted by creating a time.txt file on the root directory of the SD card with the correct date and time format (e.g., YYYY-MM-DD HH:MM:SS).

7.1 SD Card Management
- Regularly back up important video files from the MicroSD card to your computer.

8. Troubleshooting (FAQ)
- Q: Why does the camera get hot when it is charging and recording?
- A: The camera is small, making it difficult to dissipate heat quickly. This is normal and does not affect its functionality.
- Q: Why is the blue light of the device always on and the device cannot be operated?
- A: This indicates a memory error. Format the camera before use, or replace the memory card with a working one and make sure it is inserted correctly into the device.
- Q: The red/blue LED blinks five times and then the camera shuts down. What does this mean?
- A: This indicates that the MicroSD card is not inserted, is full, or is not working properly. Ensure the card is correctly inserted, formatted, and has sufficient space.
- Q: Can I watch live video from the camera?
- A: No, this is not a Wi-Fi camera and does not support live video streaming. It records directly to the MicroSD card.
