UPnP
Enable/Disable When enabled, the Camera’s Universal
Plug and Play (UPnP) feature allows a UPnP-enabled
computer to easily detect the Camera. The Camera’s UPnP
feature is disabled by default. If your computer is UPnP-
enabled, select this option.
Alternate Access Web Port
Enable/Disable If you want the Camera to be able to use
an alternate port for communications, select this option.
Then, enter the desired port number in the range from
1024 to 65534 in the Port Number field. The default port
number is 1024.
If you already have a Web Server on your LAN, then you
should enable the Alternate Port and use this port number
instead of port 80.
