For NVR models such as X5C, X5S-4W, X5S-8W, X5S-16L2, and X5S-16H, if your cameras cannot be linked in the Camera Management page on the monitor (Right Click > Menu > Camera > Camera), please follow the steps below:

If the cameras are connected to the router directly:

1. ensure the camera you tried to connect to is under the same LAN as the NVR.

2. ensure the camera is close to the NVR and there is no barrier such as a wall between them when connecting.

If the cameras are connected to the NVR’s Wi-Fi:

1. ensure the camera is close to the NVR and there is no barrier such as a wall between them when connecting.

2. ensure the camera is in configuration mode.

Please follow the steps below to check the left storage of X5C and X5S:

Right-click the mouse to go to Menu > HDD > General > Free Space.

Or, right-click the mouse to go to Menu > Maintenance > System Info > HDD > Free Space.

*Please kindly note that you can only check the free space on the monitor. On the EZVIZ mobile app, the storage in Settings > Storage Status > HDD refers to the HDD's total capacity.

For NVR models such as X5S-4P/X5S-8P, if your wired POE cameras cannot be connected, please follow the steps below:

If all the cameras failed to link to X5S-4P/X5S-8P:

Please check to make sure the power supply is sufficient for your NVR. If yes but still not working, please try the below methods and see whether these might help:

1. Please ensure the firmware of your system is updated to the latest by going to the Menu > Maintenance > Upgrade.

2. Unplug and plug in the power adaptor again, after that, click the Shutdown button then choose the Reboot button to reboot your system.

3. You may also try to reset the NVR box.

If only some of the cameras failed to link to X5S-4P/X5S-8P, to further troubleshoot, swap the functional power cable as well as port for that camera and see whether the camera will work.

-If working, it means the issue might be with the cable or the port.

-If not working, the issue might be with the camera itself.

If you have a wired kit DVR/NVR such as X4/X5 and the camera shows as Disconnected or Disabled in Menu > System Information, you can follow the steps below to troubleshoot the issue:

First, make sure that the power supply for your DVR/NVR is sufficient. If it is, but the issue persists, try the following methods:

Check if the firmware of your system is up to date. You can do this by navigating to Device Management > Advanced Settings > Maintenance > Upgrade.

Unplug and plug the power adapter back in. Then, click on the Shutdown button and choose the Reboot button to restart your system.

You may also try restoring the system to default settings by going to Device Management > Advanced Settings > Maintenance > Default.

If the issue persists only with some of the cameras, you can further troubleshoot by swapping the power cable and port with a functioning camera to see if the problematic camera starts working.

• If the camera starts working, it indicates that the issue might be with the cable or port.
• 
  
• If the camera still doesn't work, the issue might be with the camera itself."
