What I saw was from Giomania in an excellent long post and I wante dto understand why POE seems to limit comms with the camera:
"A PoE NVR is a simple plug-n-play setup, but is also less flexible and harder to work with. Some of the Dahua PoE NVR limitations are: No virtual hosts, no direct way to connect to the cameras, some camera setup options are not accessible like, zoom level, local Micro SD card, advanced exposure settings, etc., and the inability to use NTP timesync. In short, a non-PoE NVR is best for tweakers."
Link to the post:
Dahua Starlight Varifocal Turret (IPC-HDW5231R-Z)
Nvr: Nvr5216-16p-4ks2
Cam: ipc-hdbw4431r-zs
So with regards to what u can access from the nvr menus only.
Zoom no problem.
Image enhancement no problem. Can access via main view page or main menu, camera, image.
U can set the encode rates also.
With the 16 port peo nvr, I plug an unused poe port on the nvr into my network router.
This way, I can detect camera ips etc with config
tools on my pc as is without change in ip address.
To directly talk to the camera however, I need to change the PC's ipv4 info. (from my usual lan subnet to the dahua cameras subnet) 10.1.1.xxx). Then I can access the ip cameras directly.
Please see pics, hope that helps.
Please note this is the latest firmware on the nvr.
