Operating Instructions
Continuous Recording Mode ("L")
When the camera switch is set to "L", the device will continuously record video until the battery runs out or the Micro SD card is full. Video files are typically saved in segments.
Motion Detection Recording Mode ("M")
When the camera switch is set to "M", the camera will enter standby mode. It will automatically begin recording only when motion is detected within its field of view. Recording will stop a short time after motion ceases, helping to conserve battery life and storage space.

Loop Recording
The camera supports loop recording. When the Micro SD card reaches its full capacity, the camera will automatically overwrite the oldest video files with new recordings. This ensures that recording continues without interruption, provided the camera has power.

Viewing Recorded Videos
There are two primary methods to view the videos recorded by your camera:
