42 Project 6
Looking back at Figure 6-4, in the upper-left corner of the page under Internal
HTTP Server, you will see a value for Internet IP address. This is the Internet IP
address of your cable or DSL modem and router during the time you are using your
computers.
If your connection uses a dynamic rather than static IP address and your cable
or DSL connection drops at any time, this IP address will change the next time the
connection is reestablished. This means your friends will have to use a different IP
address to view your webcam web server. I??™ll cover how to give your home network
an Internet domain name to use in Project 15.
Feel free to explore the other features of webcamXP, such as the motion detector,
which senses movement within the view of one or more cameras and can send an
e-mail, record an entire video clip of the activity in range of the camera, and takes successive
snapshots of activity the camera ???sees?????”a very useful security tool. If your
camera supports pan and zoom features, these can be remotely controlled through
the web server interface, and you can set up user lists with passwords so that your
webcam server views are available only to those you select.
