If you hook up your video system to your security system, you can do a
smart (or motion) trigger. Basically the video system will archive
pictures before the event and after the event and notify you via email
or pager. Some video systems can do this without integrating into the
security system by doing video motion detection but this is slightly
less accurrate.


Most video servers allow upto 1 FPS when you're doing JPEG uploads... so
it's quite a few frames. Otherwise they can also stream 15 - 30 FPS
MJPEG video to web clients (not sure if all servers have the ability to
archive MJPEG streams though).

Anyhow, just an option. For a school, I would opt for a video server,
DVR, or a packaged monitoring system since these are easy to maintain
without hassle. The video server option is probably the cheapest.
