yep, my NVR came with 0 PoE ports.. you want a GigE uplink for 8 cameras more than likely, you might have to network those in through the GigE Lan port.
I dont like putting more than 6-7 cameras on a 100Mbit fast ethernet port, with multiple streams and local video storage the potential is there for an easily avoided network bottleneck.. Uplinks between switches should always be GigE (minimum) as a best overall practice.
