This is a very interesting videoconferencing camera from Logitech. The nice part, is that it comes with a headset that’s connected with bluetooth, leaving you free to walk around the room to make your presentation, or uh… whatever other activity would require you to walk around aimlessly.
It has a VGA CCD with 3X zoom (digital, of course) and face tracking software to allow you to do the aforementioned aimless roaming. The headset has a 7 hour battery life. Finally, it has acoustic echo cancellation, to eliminate the occasional ear piercing feeback screech.
