► How does UPnP TM work?
UPnP TM networking technology provides automatic IP configuration and dynamic discovery of devices
added to a network. Services and capabilities offered by networked devices, such as printing and file
sharing, are available among each other without bothersome network configuration� In the case of
Network Cameras, you will see Network Camera shortcuts at My Network Places�
► Enabling UPnP port forwarding allows the Network Camera to open secondary HTTP port on the
router, not HTTP port, meaning that you have to add the secondary HTTP port number behind the
Network Camera’s public address in order to access the Network Camera from the Internet� For
example, when the HTTP port is set to 80 and the secondary HTTP port is set to 8080, refer to the list
below for the Network Camera’s IP address�
From the Internet In LAN
http://203.67.124.123:8080 http://192.168.4.160 or
http://192.168.4.160:8080
► If the PPPoE settings are incorrectly configured or the Internet access is not working, restore the
Network Camera to factory default; please refer to Restore on page 75 for details� After the Network
Camera is reset to factory default, it is accessible in LAN�
HTTP Advanced mode
To utilize the HTTP authentication, make sure that your have set a password for the Network Camera
first; please refer to Security on page 26 for details�
Authentication: Depending on your network security requirements, the Network Camera provides two
types of security settings for a HTTP transaction: basic and digest�
If basic authentication is selected, the password is sent in plain text format; there can be potential risks
of being intercepted� If digest authentication is selected, user credentials are encrypted in MD5 algorithm
and thus provide better protection against unauthorized accesses�
HTTP port / Secondary HTTP port: By default, the HTTP port is set to 80 and the secondary HTTP port is
set to 8080� Also, they can be assigned with another port number between 1025 and 65535� If the ports
are incorrectly assigned, the following warning messages will be displayed:
To access the Network Camera in LAN, both HTTP port and secondary HTTP port can be used to access
the Network Camera� For example, when the HTTP port is set to 80 and the secondary HTTP port is set
to 8080, refer to the list below for the Network Camera’s IP address�
In LAN
http://192.168.4.160 or
http://192.168.4.160:8080
