This will increase your bandwidth, slow down the rest of the network, and present a potential security risk to the network itself.

The cameras I worked with had a built in FTP client and a timer. You could set up the timer to take a still image every so many seconds or minutes and transfer the image to a web server via FTP. This will probably give you the exact results you are looking for. Then the only thing you need is basic Javascript to change the image every 15 seconds if you don't want the user to have to refresh the page manually.
