User's Manual PNVR500 series
18
If the distance between the NVR and IP camera is more than 100m
2.4.6.
You may extend the transfer range by connecting a switching hub or PoE device between the Ethernet port and IP
camera if desired distance is longer than 100m.
Connecting cameras directly to a general switching hub requires camera connected to a separate power
supply.
A switching hub connected for extending transfer range of a single channel should be connected to one
camera only.
