I have a ZM-SS7009D8-S (v188.8.131.52) and a ZP-NE14-S (v40.0.3.02).
Using Zviewer 184.108.40.206 I can access both systems though I have to drag them each time. Actually, I only have to drag the 8ch system since also it sees the four channels of the smaller system. The picture quality is very poor unless you enlarge one of the cameras.
Using Zviewer 220.127.116.11 I can only see the 4ch system and only via IP not the NVR itself. This version remembers the four cameras as IP cameras so I don’t have to drop them again and again but it doesn’t see the 8ch system at all.
Using IP Search I can’t see the cameras of the 8ch system at all. I believe they have IP addresses, but they’re nowhere to be found.
I haven’t been able to revert to earlier firmware on the 8ch since it doesn’t see the file on the USB stick. And last week, the 4ch updated itself. It used to be at 18.104.22.168 IIRC.
I can use the PC to access the cameras however playback is not supported. I can use the mobile apps but it’s painful to playback if you can get it to work at all.
Using Xeoma it only finds the 4ch system, nothing finds the 8ch system.
So that’s my layout and the bottom line is I would love to have some consistency of which now I have nothing.
Sorry for my rambling, but any suggestions would be most welcome, including how to properly downgrade to earlier firmware.
