Lifecam Cinema
Recently Microsoft added the Lifecam Cinema to list of Deviced Optimized for the Office Communicator.
This device features a 720p HD Ready Widescreen sensor, 30 fps, Autofocus, Real glass lens etc. More info can be found at: http://www.microsoft.com/hardware/digitalcommunication/ProductDetails.aspx?pid=008&active_tab=overview
Over here in The Netherlands the device is priced around 70 Euro, which is, in my opinion, a very reasonable price for such a type of device.
Only one small remark, in full screen HD mode it can spit out video frames at a rate of approximately 1.5 Mbps
. So be prepared at the Edge!! (Or block HD Video, but if that is the case you shouldn't even read this post or buy the device!!)
