This articles will describe, how to connect up to 16 cameras (IPC) to the NVR16.
Some detail in the articles applies to the NVR4 and NVR8.
The NVR16 rear panel
When looking at the rear panel of the NVR16 (and NVR8), you will see the following connections (only relating to IP cameras) :

The build-in switch and the Ethernet port is logically separated.
Since you only can connect 8 cameras directly to the NVR16, you need to connect the rest of them, through a switch.
Connecting to the Ethernet port
First possible method is, to connect a additional switch, to the Ethernet port (if the NVR isn't already connected to a network).
In this example, there are 8 cameras directly connected to the NVR. The NVR is then connected to a PoE enabled switch for uplink and camera streams.
Now, the PoE switch will not feed the NVR, but disable the 48VDC on the port, where the NVR is connected.
The cameras connected to the PoE switch will receive 48VDC. These cameras must re reconfigured with a new IP address, accordingly the the network.
Connecting to a PoE port
The second possible method is, to connect a PoE switch to a PoE port on the NVR. Again, the connected switch will not be powered from the NVR.
In this example, there are 6 cameras directly connected to the NVR. The NVR is then connected to a switch for uplink only. 1 or more PoE enabled switches is connected to a PoE Port on the NVR. The NVR will not power the PoE switches.
The cameras connected to the PoE switch will receive 48VDC. These cameras does not need to be reconfigured with a new IP address.
Limitation
The Ethernet port on the NVR is limited to max incoming bandwidth of 200Mbps, and outgoing bandwidth of 160Mbps
