and "exposure" -- in the advanced settings . Exposure is shutter
speed, though you wont know the actual value -- I think the slowest
speed is a second or so. Gain is like ISO. This is using the Logitech
software. There is third party software than can be used for remote
(and local) access, sequences at intervals, pan, tilt scripting to some
There is manual focus in the Logitech software. It is really precise
and easy to use on a screen.

- Here is another kind of "orbit" webcam, also good for capturing panoramic views
... I've programmed it to look where I want pretty much
This movie is actually with my Logitech/Sunex webcam, being about the central 140 degrees of the fisheye view. The lighting is from the LED on the webcam -- a handy thing for closeup views, pity it is red.
