To turn off, slide the ON/OFF/Auxiliary Light Switch (1) up and hold it for 3 seconds until the light turns off. If the device is in standby mode, it will automatically turn off after 1 minute of inactivity.
Audio Recording:
In standby mode (blue light on), slide the Audio Recording/Saving Switch (7) to 'REC' position. The blue light will flash, indicating audio recording is in progress. To save the audio file, slide the switch back to the 'SAVE' position. The recording file is automatically saved every 30 minutes to prevent data loss.
Video Recording:
In standby mode (blue light on), slide the Video Recording/Saving Switch (6) to 'VIDEO' position. The green light will flash, indicating video recording is in progress. To save the video file, slide the switch back to the 'SAVE' position. The video file is automatically saved every 10 minutes to prevent data loss.
Photo Taking:
While in video recording mode, press the Photographing Button (2) once. The blue light will flash once, and a photo will be taken. Photos are saved in the 'VIDEO' folder. Note: The photo key only works during video recording.
Motion Detection:
To enable motion detection, connect the camera to a computer and open the 'time.txt' file. Change the 'motion:0' value to 'motion:1'. '0' means motion detection is off, '1' means motion detection is on. Motion detection is off by default. When motion detection is active, the device will stop recording if no movement or light changes are detected for 1 minute (blue light on). If movement or light changes are detected, it will record continuously (green light flashing).

Loop Recording:
The camera supports loop recording. To enable loop recording, connect the camera to a computer and open the 'time.txt' file. Change the 'Loop video' setting from 'N' (Close loop video) to 'Y' (Loop video). If the memory card becomes full, the camera will overwrite the oldest recordings. If set to 'N', recording will stop when the card is full.
Synchronize System Time:
1. Turn on your camera after plugging in your micro SD card. It will automatically generate three files: "time.txt", "VIDEO", "AUDIO".
2. Click "time.txt" to show "date and time". Change it as you need. “Format (year month date hour minute second)”. Then save your time and unplug your device. Now you can start recording at your set time.

2. Connect the device to your computer successfully, and the red light will stay on. You can then copy the selected files or folders to your computer.
Tips for Computer Connection:
- The process is the same as copying any file from a USB flash drive to your computer.
- If your computer cannot recognize it and the USB Disk doesn't pop up in a few seconds, please reset your device and connect it again following the steps above.
- We suggest you read the video files from the TF memory card via a card reader. This may provide smoother playback for large video files.
