I have the same issue. I cant see a connection column.
How did you correct this please?
As a work around, I did CTRL A to select everything on the page, then pasted onto a word document and could see what you mean Phil23 by the NVR's ip address followed by the ports, 65001. 65002, 65003.
So i inputted this into IE address bar and can navigate to the cameras that way. Saved each camera to IE favourites.
Maybe someone has the same problem...
i solved this way:
On camera management web pages, click Safari in the menu bar and you'll see the "Setting for this website" option, and click on it.
Deselect the "Enable content blockers"
OSX 10.13.4 - Safari 11.1 (13605.1.33.1.2)
