and it indeed work(ed) when i tried it (about 2 years ago), to spy on what
my dog was doing when i wasn't home. i found one problem: the way that
'motion' is defined, is by the number of pixels of difference between two
consecutive images. this made it hard to use with light canges (in the
dak, movement causes only a few pixels to change, so it requires a low
threshold. in the light, movement causes much more pixels to change. it
was also not possible to define where in the pictures to make these
calculations - it takes the entire picture for this calculation, whether
you like it or not.

thus, you need to do some "calibrating" for your lighting and movement
conditions, and then it works quite well. it also only records once
picture every X seconds, so it does not fill your hard drive too quickly.

good luck,
