Troubleshooting Common Issues1. No Video Display:
* Check the connection between the camera and the network video recorder (NVR).
* Verify that the camera and NVR are powered on.
* Reset the camera and NVR to default settings.
2. Video Lag or Freezing:
* Increase the frame rate and resolution of the camera.
* Reduce the bit rate of the video stream.
* Ensure the network has sufficient bandwidth.
3. No Audio:
* Check the audio cable connections.
