A while ago we at Inner Drive attempted to install a new Webcam which, in short order, stopped working. Logitech promptly sent a replacement, which so far works fine.
So the Inner Drive Webcam is now much sharper, and less prone to falling, than it used to be:
The only disadvantage is that it doesn't work in Terminal Server mode, so if the server kicks over unexpectedly, the Webcam will be static until we can get to a terminal and fix it. (We'll experiment with that later on.)
Also: The camera, a Logitech QuickCam Orbit MP, is adjustible--so it will change angles every so often.
We are very happy.
