Interesting idea. I'll leave that as an exercise to the reader.

Here's the list of camera domains/IPs http://tlrobinson.net/bigbrother/urls.txt and the paths to the viewer page and MJPEG, respectively:

    a.href = baseURL + "ViewerFrame?Mode=Motion&Language=0";
    img.src = baseURL + "nphMotionJpeg?Resolution=160x120&Quality=Standard";
