Hikvision NVR 7600 - ip cam add issue. Newbie.

It looks like you have a 4 channel NVR with 4 PoE ports.
The PoE channels are pre-configured, and as you have found you can't add or delete as all 4 channels are initially PoE channels.
But what you can do is pick a PoE channel you won't be using and use 'Modify' (web GUI) or 'Edit' (HDMI/VGA interface) to change to Manual mode and configure the IP address / protocol (presume Hikvision) and user/password values.
 
Hi - no video showing in live view. Viewing on PC. Plugin installed eventually.
So much for plug n play lol.
Many thanks for the help so far

Thank you so much, I couldn't see the wood for the trees .

Now to set it all up
