Network Settings

Although the embedded web server is mostly self-sufficient for most people, you may find need to adjust the settings relating to how i-Catcher Video Server interacts with your network, especially in you run more that one copy on one computer. The Network section of the main window has 3 settings that allow you to tune this component.

IP Address to listen on

Computers use IP Addresses to uniquely identify themselves on the internet and on local network segments. If your computer participates on more than one network segment, or is connected to both a local network and the internet, or you are using virtual hosting software, you may wish to specify which IP Address to specifically use for listening for web requests and serving images. 

If you are unsure of this setting, or you don't mind which IP Addresses i-Catcher Video Server uses, you can leave this setting with the default of 0.0.0.0, which means "use all available addresses".

If you wish to run a "local only" server, that is, only processes on the same machine as that which i-Catcher Video Server is running on, you can enter the the special "loop back" IP Address, 127.0.0.1.

Please note, that it is not possible to use multiple specific IP Addresses.

Port to listen on

All connection-based services (such as web servers) require a port to listen on. This port is used to identify the service that a client wishes to connect to. Since i-Catcher Video Server delivers its video images as a web server, the default port is 80, which is normally used by conventional web servers. In most situations this setting will be suitable, however if you are running i-Catcher Video Server on a computer which acts as a web server, you may find that when you start i-Catcher Video Server, an error occurs stating that it was unable to start the web server component. i-Catcher Video Server will still capture images, but you will not be able to see them in your web browser. To avoid this, you can enter a different port number. If you do this, you will also need to put this port number after a colon ( : ) on the end of the hostname of the computer i-Catcher Video Server is running on, for example camera.server.net:81.

Some commonly used ports to avoid using (for standards and/or conflict reasons) are 25 and 110 (Email), 23 (Telnet), 113 (ident), 137-139 (Microsoft networking), 443 (Secure HTTP), 53 (DNS data transfer), and 20/21 (FTP).

Maximum Connections

If you are in an environment where you have little network/internet bandwidth to transfer data over, you may wish to limit the maximum number of permitted connections. The default of 10 should be fine for most situations. Note that if you change this value, it should be at least the same as the number of ports being captured, that is, one connection per port.

Confirming the settings

Any changes to the network settings will not be applied until you click on the "Set" button. A message box will pop up informing you that the settings have been successfully changed. Note this does not mean that the web server was able to start successfully, you may still receive an error stating that the web server could not start. The pop-up message only indicates that making the changes to the desired settings was sucessful.
