If you don’t already have a router you will need to purchase one and configure it as part of you

network.

Useful commands

ipconfig – utility to see computer IP properties

ipconfig /release – release the current IP address – need DHCP enabled

ipconfig /renew – renew the IP address by telling the router that it needs DHCP enabled

ipconfig /all – show all IP config properties

ipconfig /? – show help on IP config

ping – utility to test the connection with other IP address

ping 192.168.123.254 – attempt to ping IP address by sending a small packet

ping –t 192.168.123.254 – continually ping IP address until you close command window or hit

Ctrl+C.

DHCP – Dynamically assign IP address to requesting devices (e.g., computer, camera). This

means when you connect a computer to the router the computer will automatically negotiate an

IP address from the router.

Port Mapping – Section on router where you specify which port will be mapped to which

device. With a router you are sharing a single Internet connection with multiple devices and

for the cameras you need to have each camera on a separate port if you want to access the

camera from outside the router (i.e., Internet).

opened for communication towards the GuardNVR.

The following port needs to be opened for connections going outwards from the

GuardNVR:

1. TCP Port 3389: Remote Desktop Connection port. This port is used in support

cases only.

RTP uses two UDP ports per stream (versus one in the old streaming format), one for

RTP (the video stream itself) and one for RTCP (QoS signal stream), limiting the

software to a maximum of 64 concurrent streams. This number can be limited (e.g. for
