6. Maintenance
- Cleaning: Regularly clean the camera lens and PIR sensor window with a soft, dry cloth to ensure optimal performance. Avoid using abrasive cleaners.
- Battery Replacement: Replace batteries when the low battery indicator appears or when performance degrades. Always use fresh, high-quality batteries.
- SD Card Management: Periodically format the SD card in the camera's menu to maintain optimal recording speed and prevent data corruption. Back up important files before formatting.
- Water Resistance: While the camera is water-resistant (IP67), ensure all latches are securely closed to prevent water ingress, especially during heavy rain or snow.

7. Troubleshooting
- Camera not turning on: Check battery installation and ensure batteries are fully charged. Try a different set of batteries.
- No pictures/videos captured: Verify the camera is in 'ON' mode. Check PIR sensitivity settings and ensure the SD card is properly inserted and has sufficient space.
- Poor image/video quality: Clean the camera lens. Ensure the camera is mounted stably to prevent blur. Check resolution settings.
- False triggers: Reduce PIR sensitivity. Ensure the camera is not pointed at heat sources or moving branches that could cause false detections.
- SD card error: Try formatting the SD card through the camera's menu. If the issue persists, try a different SD card.

9. User Tips
- Optimal Placement: For best results, place the camera facing north or south to avoid direct sunlight interfering with the sensor or causing overexposure in photos.
- Clear Line of Sight: Ensure there are no obstructions (like tall grass or branches) directly in front of the PIR sensor that could block detection or trigger false alarms.
- Battery Life: Use high-quality alkaline or lithium batteries for extended battery life, especially in cold weather. Consider using an external power source for long-term deployment.
- Test Mode: Utilize the 'SETUP' mode's test function to walk in front of the camera and verify the detection zone before leaving it in 'ON' mode.
- SD Card Capacity: While the camera supports up to 256GB, consider using a smaller, reliable card (e.g., 32GB or 64GB) if you don't need massive storage, as larger cards can sometimes be more prone to issues if not properly formatted or if they are of lower quality.
