I had many hours of fun working this out and many frustrating wtf moments
but reading and reading and more reading on this forum got me to a point where it seems easy now
best way i found was first set up each camera via sadap tool and note down its ip address eg 192.168.1.288, you should go to the nvr and open the box that lists all of the cameras
eg cam1 lets say =
192.168.254.1 this number is the nvrs internal poe number.
lets change it to the number you gave the camera via sadap also write them down in a little black book too.
so now that box will drop down a menu to add camera manually
enter the cameras ip number eg 192.168.1.288 then fill in the box that says user which will be admin,then fill in the camera password
then hit save it should say connecting to network the connected, then if you plug this camera into a poe switch in any part of your network and your nvr is on the same network it will pick it up regardless it doesn't have to be plugged into the nvr
If you use plug and play which is the 192.168.254.1 i can be more frustrating when there not plugged into the same port especially if you use different passwords and the camera has to be plugged into the nvr hope it helps out
