When you want to connect or reconnect a NV-CAM30W camera to a Nivian 830W recorder because it has been disconnected or deleted from the recorder, follow these steps.
1. The camera must first be connected via ethernet cable to the local network where the NVR is located
2. In the main screen of the Nivian recorder, right click on the mouse button
3. Select "Video management".
4. Log in with user name and password
5. Select "Match Code" from the second button in the top menu
When the cameras appear in the left column that you want to add, click on "Exit"
Then "Yes" again to confirm
Once they have been added, the cameras will be displayed on the recorder, and you can disconnect the camera from the local network and keep them added to the NVR via wifi.
