On my machine at least, xawtv is just a pretty front-end for v4lctl. 
You can write bash/perl/python scripts calling v4lctl to automate the
recording, if 'motion' [excellent suggestion M. Chalaron] doesn't do
all you want.  'man v4lctl'.  It is really quite impressive.

Incidentally, avi files will soon get pretty large, so you'll probably
want to compress on the fly, or with a lag in the background.  MPEG
will be easiest, but I prefer the idea of Ogg Theora or the BBC's
Dirac (neither is well supported yet, unfortunately).
