5. Operating Instructions
Recording Modes:
- Loop Recording (L Mode): In this mode, the camera continuously records. When the Micro SD card is full, the oldest files will be automatically overwritten by new recordings.
- Motion Detection (M Mode): When motion is detected, the camera will automatically start recording. This mode helps conserve battery life and storage space by only recording relevant events.

Image: The loop recording feature ensures continuous operation by overwriting the oldest footage when the memory card is full.

Image: Motion detection captures critical events, saving storage and power by recording only when movement is sensed.
Automatic Night Vision:
The camera is equipped with four infrared sensors that automatically activate night vision in low-light conditions. This ensures clear recordings even in complete darkness.

Image: Automatic night vision provides clear, sharp recordings in various lighting conditions, from bright daylight to complete darkness.
Gravity Sensor:
The built-in gravity sensor detects the camera's orientation. If the camera is inverted, it will automatically adjust the video recording angle to ensure the footage is always upright.
