@HarryH - The NVR assigns the camera an IP address usually in the 10.x.x.x range.
That is probably a Dahua OEM, so it probably has a similar look and feel:
To get into the camera GUI from the NVR, you need to first access the NVR GUI by going to a computer and opening up a browser (preferably Internet Explorer but Pale Moon will work as well) and type in the IP address of the NVR and login that way. Next go into the camera settings page on the NVR and look for the Microsoft e Web Browser and select it and it will go to the camera GUI (photo credit bigredfish from his PSA thread). Your screen may look a little different to get into the camera gui and see if doing it this way gets you access to some other features the NVR is blocking - do not worry about the Port number and circle as that was from another issue someone posted.
Simply select the blue IE icon and it will go to the camera GUI and from there you can set the camera parameters.
OR
Those cameras are probably Dahua OEM, so you should be able to factory reset them and then it sets the IP address to 192.168.1.108
OR
You can use your NVR and feed the cameras from the NVR straight into BI.
In BI, you select add camera and put the IP address of the NVR into the IP address location. Put in username and password and hit find/inspect and let BI do its thing.
Then about halfway down is a pull down for Camera number and pick camera 1 and then hit ok. The camera should show up. Then add camera and the select copy and copy this camera and then change the number 1 to a 2 and repeat for your cameras. OR depending on your NVR, it may populate all the cameras in the main and substream pulldown boxes and you just select a camera number and then add another camera and select the next pulldown.
