4.3 Changing network ports
This chapter explains how to change different network ports, which are used by a GuardNVR
system.
4.3.1 Changing GuardNVR video ports
GuardNVR ships with the default UDP port range set to 4096 – 4223, which are used for video
streaming. You may either decrease or increase this range, for that purpose you should change
the amount of opened UDP port on your router, firewall and on GuardNVR itself. To change
GuardNVR UDP ports go to Settings->Network Settings.
The amount of UDP opened ports have to correspond to number of camera streams
you want to have simultaneously. For instance, you have GuardNVR with 4
connected cameras, if you launch two GuardNVR clients of GuardNVR
simultaneously 16 camera streams will be created (i.e. 4 camera streams for each
client) and this doubled because of RTP streaming method. So you have to open 16
UDP ports. You have to use even numbers for the start and end port of the UDP
port range.
4.3.2 Changing TCP port
GuardNVR ships with the default TCP port set to 80. By maintaining the default setting
GuardNVR may be accessed remotely by simply entering either the local LAN address (if
accessed from within the network) or the static IP address if accessed from outside the
network. If this port needs to be changed, follow the steps below.
1. Logon as Administrator.
2. Double Click the Support folder from the Windows desktop and select Internet
Information Services by double clicking.
3. Proceed through the following path (local computer)->Websites
and right click Default Web Site. Select Properties.
4. Under the Web Site tab you will find a section Web Site Identification. Change the
TCP port to the desired value and click OK to confirm.
When you make a change to a TCP port other than port 80, there are some implications that
must be taken into account.
When you access GuardNVR locally by selecting Video Browser from the desktop, the
link
http://localhost/guardnvr/browser is launched. This link with have to be renamed
as follows if a value other than port 80 is used: http://localhost:xx/guardnvr/browser
where xx is the value that you selected.
When you access GuardNVR from Internet Explorer remotely you would do so by
selecting
http://xx.xx.xx.xx which is your static IP or internal IP address assuming you
