OK, I am using NVR 4.0 firmware, under camera settings cameras are listed on the screen, nothing to the right.
Left side has display config, video parameters, poe channel. privacy mask. The word camera management is not there
I'm not familiar with the V4.x firmware - so can't point you in the right direct with actual detail - but the Enable for Virtual Host is here on the 3.4.x firmware, after which the links should appear :
Yes, great. After that I called to find I was 2 firmware version down. After I could not get the password screen, I had to default the setup and start over.
4 hours later I am almost there.
DYNDNS does not work anymore. I entered the address into the nvr, but it always fails. It was working and the setting are good.
