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).
2.4.6.2.2 Configuring firewall
General information about firewalls and their configuration is given in a previous section. The
most important notes are:
The following ports need to be opened for connections going towards the
GuardNVR:
1. TCP Port 80: Web application
2. TCP Port 1518: Control connection
3. UDP Ports 4096 till 4223: Video streaming
4. TCP Port 3389: Remote Desktop Connection (Optional). Frequently asked by
support when you have an issue).
5. TCP Port 5666: Q-Monitor service
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
security purposes) or extended using the Settings > Network settings page. In that
case, Quadrox advises to open a number of spare ports to avoid switching issues, e.g.
4 ports extra. The first port in the range should be even.
