I have been using a laptop with a webcam built into it for AIM video calls - it has worked amazingly well. So, I purchased a webcam to mount on my desktop monitor with my other computer. It worked poorly - the mic was not picking up my voice very well - even though I was hearing the other person very clearly. I tried two others - same problem. I don't think I'm doing anything wrong - I follow set up instructions and then adjust settings (for maximum mic volume) Any thoughts as to what I might be doing wrong or any recommendations for a good add-on webcam? I have tried MS Lifecam 3000, MS Lifecam 7000, and also tried a Creative Labs product (don't remember the model #) Thanks!
