VideoEdge NVR 4.1 Release Notes

2. Open the port on the firewall

Whichever port has been chosen in the above step must be accessible through any WAN

firewall so ensure that this port is open in any such device.

3. Server Side (NVR) – issue the command from /bin

./iperf -s -p <Server_port_number> s: means server mode, p: port server is listening on

4. Client Side (victor Client)

When you startup the client – iperf to be in client mode. The command to use:

iperf -c <IP NVR ADDRESS> -p <Server_port_number> –P4 –t 10 –w 1048576 c: Client

mode, and the IP address of the NVR server

-w represents the TCP window size in bytes. The recommended window size has been

specified above.

The final line is a sum of all the data, indicating the totals. The total amount of data sent

was just over 1Gb at a rate of 929 Mbits/sec (this is over a gigabit connection). As you

can see, the program used almost the full amount of bandwidth available to it.

Internal WAN testing has proved that the client/server when operated within bandwidth

constraints and limiting the bit rate to a smaller percentage of the available circuit,

operations such as PTZ control, clip download and instant playback will work

satisfactorily. Limiting the number of cameras streaming will provide the best user

experience. The network topology, configuration and usage have a great impact on

bandwidth usage (e.g. available). It is recommended that users monitor their network for

at least a week using iperf to have a good understanding of the bandwidth available and

thus insuring that the bandwidth used by the victor client in a WAN configuration is below

the bandwidth available.
