7. Troubleshooting
- No Power/No Image:
- Verify that the Ethernet cable is securely connected to both the camera and the PoE switch/NVR. If using a standard router, ensure the 12V DC power adapter is correctly connected and functioning.
- Check the power source for any issues. - Cannot Access Camera:
- Ensure the camera is powered on and connected to the network.
- Use the 'AJDevTools' or 'SADP' PC tools to confirm the camera's IP address and network status.

- Confirm you are using the correct login credentials. - Poor Image Quality:
- Clean the camera lens to remove any dust or smudges.
- Ensure there are no obstructions in the camera's field of view.
- Check network bandwidth; insufficient bandwidth can affect streaming quality.
- Verify that the camera's resolution settings are configured for 4K/8MP. - False Motion Alerts:
- Adjust the detection sensitivity in the camera's settings.
- Refine the detection zones to exclude areas with frequent irrelevant movement (e.g., trees swaying, busy roads). - Night Vision Issues:
- Ensure the camera's IR LEDs are not obstructed.
- Check for strong light sources near the camera that might interfere with night vision.
