- NVR Port: Verify that the NVR port is functioning correctly. Try connecting the camera to a different PoE port on the NVR.
- Reboot System: Power cycle your NVR and the camera (if possible) to refresh the connection.
7.2 Poor Image Quality
- Clean Lens: Ensure the camera lens is clean and free from dirt, dust, or smudges.
- Lighting: Verify that there is adequate lighting in the area, especially for color night vision. Adjust camera position if glare or reflections are an issue.
- Resolution Settings: Check the camera's resolution settings on your NVR to ensure it is set to 4K (8MP).
7.3 Motion Detection Not Working
- Enable Motion Detection: Confirm that motion detection is enabled in your NVR or app settings for the specific camera.
