[ALUG] Webcam as security monitor

[Greg Thomas]

Just found an old webcam at the back of a cupboard, plugged it in to
my Ubuntu box, installed Camorama, and woot! it works.

Which set me to wondering. Camorama can be to record a picture from
the webcam every (say) 20 minutes. What I was wondering was is there
is any software out there that records the picture at a set interval,
but only if the webcam image changes (you'd presumably need some sort
of change threshold, to cope with minor changes).

Any thoughts, anyone?
