Same price as the Unibrain.
I haven't found the detailed datasheet for the iSight (i.e. does it work
with Linux, and is it a DV camera (putting out compressed video) or not
(putting out rectangular grids of pixels))
Autofocus can be a bit of a problem in this application (but perhaps it can
if the focus changes, it changes the optical transformation, which then
Superficially, at least, it looks like it uses the same 1/4" CCD sensor as
the Unibrain camera.
