8. Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| No audio in recordings or live feed | The LN79 camera is designed for video recording only and does not support audio capture. | This is expected behavior. The camera does not have audio recording capabilities. |
| Motion detection is too sensitive, leading to false alarms | Motion detection sensitivity is set too high, or human detection mode is not enabled. | Adjust the motion detection sensitivity settings within the mobile app. Enable the human detection mode to filter out non-human movements. |
| Cannot connect to WiFi | Incorrect WiFi password, camera too far from router, or router settings interference. | Ensure the WiFi password is correct. Move the camera closer to the router. Check router settings for any restrictions or firewalls. Restart both the camera and router. |
| Battery life is shorter than expected | Continuous recording, frequent motion detection triggers, or extreme temperatures. | Ensure the camera is fully charged. Reduce continuous recording time if possible. Optimize motion detection settings. Operate the camera within recommended temperature ranges. |
| Micro SD card not recognized | Card not inserted correctly, card is faulty, or needs formatting. | Reinsert the SD card. Try a different compatible SD card. Format the SD card using the camera's app or a computer. |
