[K12OSN] Capturing snapshots from camera

[Brian Chivers]

I've been asked to setup a camera over looking our College's playing field to capture an image every 
30 minutes so we can see how much it is being used.

I have a camera with that has a composite video output that I'd like to use and a video input card 
(not sure if it linux compatible, if not I'll get one that is *grin*) but I'm not sure what software 
to use to do this.

Not worried about motion sensing just need a jpg or something every X minutes

Does anyone do this ? Any ideas or pointer where to start.

Thanks
