APPENDIX 1. –How to run IP Camera UPnP

The most troublesome issue when you setup an IP Camera

is that you have no idea what the IP

address of this device is. Now IP Camera

supports the UPnP (Universal Plug and Play) protocol

which makes it easier for you to examine it; however, it is a pity that Microsoft Windows XP

doesn’t start this service by default. Therefore, the following procedures will help you to turn it on

and discover your IP Camera

step by step as shown in Figure1 below.

1. Check the IP class of your PC

In most case Microsoft Windows XP

will assign an IP address, 169.254.*.*, automatically with a

subnet mask, 255.255.0.0, if the DHCP server is absent, while the default IP address of an IP

Camera

is 192.168.1.168 with a subnet mask of 255.255.255.0. There won’t be any

communication due to different IP class domains, and you have to modify the relative settings or

the UPnP protocol won’t work; however, checking your own IP address is necessary. Here are

the procedures to check and modify them.

Step 1: From the Start menu, point to Settings, and then click Control Panel. See Figure 2.
