Hi all, hope someone can help...

I have 4 Dahua cameras, all of which are working on my network and have got them presenting images to iSpy and other PC based management software.  (and I know the IP addresses) - all working well.

I just bought a TP-Link 16 CHannel NVR1016H VIGI.  got it all set up and working and yet only one camera is discovered and now operating in the NVR.

I simply cannot get the other 3 to discover nor can i add them manually with IP address and creds.

any help anyone ??
