2. TCP Port 1518: to allow external users to receive alarms, control PTZ cameras, send
commands, etc. This is called the WebCCTV control signal.
3. UDP Ports 4096 thru 4223: By default the WebCCTV uses a range of UDP ports to
transport video streams. These UDP ports are not listening all the time. The WebCCTV
software enables them at random to enhance security.
Typically when the UDP ports are not opened correctly, the user only sees the web-
interface but no live images.
To allow Quadrox support personnel to get remote access to the WebCCTV, TCP Port
3389 needs to be opened for Remote Desktop Connection.
If the Video Server is monitored by the Quadrox Monitoring Department, TCP Port
5666 needs to be opened.
A firewall can be placed on several positions in the network. The most common place is at the
edge of the corporate network, or in other words between the corporate network and the
Internet. Recently it also became popular to place a firewall to protect the network traffic from
a single computer. A firewall that is placed between the computer and the network is referred
to as a ‘Personal Firewall’ application.
In practice, a corporate network firewall is often integrated with the router connecting the LAN
and the internet. For more information on routers, see the section on connecting the
WebCCTV to the internet. A personal firewall is software running on the computer that it
protects. Personal firewall applications can be installed separately but are also included in the
Windows XP operating system (Service Pack 2) and in many virus protection software
packages.
There are several scenarios where firewall configuration is necessary:
1. A user on a corporate network or at home behind a broadband router wants to access a
WebCCTV on the Internet
2. A user on the Internet wants to access a WebCCTV on a corporate network.
These situations are explained in more detail in the section on how to connect your WebCCTV
to the internet. If a user on a corporate network wants to connect to a WebCCTV on another
network, a logical combination of these two situations can be applied.
1. A user with a personal firewall application on his computer wants to access a
WebCCTV on the corporate network or on the Internet.
2. There is a personal firewall application installed on the WebCCTV.
