I need a webcam and I'm looking for the best quality one I can find. I'll be using it for video conferencing and it'll be sitting atop my 30" ACD. If I use a white board during a meeting or presentation, I'd like the cam to have sufficient zoom to be able to zoom in on what I'm writing about 8'-10' feet away. My lighting is generally very good. It must also have a good audio pick up as I might be talking while I'm writing at the white board. It would be great if the webcam also had a high quality camera to take a picture of what's being written as well. Any suggestions? BTW, is anything like this available in stores (my guess is I wouldn't find something like this at Best Buy)? I just hate the idea of the mail order return process if it isn't something that works.
