The company I work for has done something like this for a local construction company. Basically, we set up a modest (P-200, if I recall correctly, maybe 64 MB of RAM) FreeBSD machine with a webcam and a video capture card (Happauge-based, I believe) to take pictures of a site they were building. Cron was used to take a picture every fifteen minutes, dial up another computer (also FreeBSD-based), and upload it; once there, it was merged with other pictures into movie files, made available in an archive, etc. Sorry to be vague on the details -- I had to rebuild the box once, so I wasn't involved in software choices, etc. (The ImageMagick tools would probably be a good starting point for merging pictures.) My point is that we did the job pretty well with modest equipment, so I think that, at least for time-lapse pictures, it is definitely possible to do what you're after. Oh, one other thing -- I do remember fooling around with capture utilities that basically acted as a web server: every time you connected to the machine, it would capture a picture and send it back. That might be useful to you. I can't remember the name of the program, but maybe someone else can help me out. Hope this helps, Hugh -- Saint Aardvark the Carpeted aardvark@saintaardvarkthecarpeted.com Because the plural of Anecdote is Myth.
