GeoVision Case Study for GV-Hot Swap Recording Server System - Manual (Page 10)

4.3 Network Requirements
In the recommended installation illustrated above, the GV-Recording Server receives video
from the 128 GV-IP Cameras installed in the building, and then transmits the 128 IP channels
to GV-Control Center. In this case, one Gigabit Ethernet port for the incoming 128 channels
and one Gigabit Ethernet port for the outgoing 128 channels are sufficient. In addition, 2 PoE
switches are applied to divide a local area network into two segments (receiving and
transmitting) for efficient network.
Note: GV-Hot Swap Recording Server System has three built-in Gigabit Ethernet ports with 3
default IP addresses: 192.168.0.200, 192.168.0.201 and 192.168.0.202 with the same subnet
mask 255.255.252.0.
However, if you are not following the recommended installation (Ex: more outgoing channels
or higher resolution cameras or no PoE switches used to divide the network traffic), you may
need to set up additional Gigabit connections to avoid network bottleneck. The numbers of
Gigabit network cards required to receive 128 channels and transmit 300 channels are listed
below according to the resolution of the source video.
