Hey
@gansle , you got me to thinking with your screencaps.
You CAN access the 37777 cams with the blue IE icon,
I was wrong. sorta. I wrongly assumed you were using the built-in PoE ports.
See below. Buddy I helped installed a 5432 16P NVR. He used all 16 poE ports and then added a switch for additonal cams. They DO show up and are accessible via the blue IE icon on the NVR. We DID add those manually, but you cant add the 10.1.1.x cameras on the PoE ports manually.
Basically
when using the built-in PoE ports, the NVR will assign them an IP (10.1.1.x) and a local port (1,2,3) and they will automatically populate the bottom pane. You cant add them manually or it will mess up.
On cameras
connected via external switch (like the ones shown at 192.168.1.x) you search for them in the top pane, and then add them to the bottom manually. These you need to typically add one at a time and login to the camera and assign it an IP other than .108 as that is the default IP for all Dahua cams. Then add another and assign it another IP and so on, one at a time.
