So I have an older 4208-8p NVR. I'm looking at a SD59225U-HNI IP Ptz. The 4208 does have POE+ so I'm confident it will power the ptz. However, will I at least have control to move the camera within the NVR? I'm assuming I won't be able to hit the menu for full settings without hitting the camera GUI but once set I can work the thing via the NVR right? Don't need to hook up 485 comm wire to the NVR to do so- all commands transfer via cat 6? Thanks!
