The reactions of my cat video correspondents were very positive, without knowing that I had changed webcam (before I had Quickcam Logitech, which was not bad either) They all responded: best picture, better sound, in short, they see me and hear me better better. The integrated microphone works well. It can be easy adjustment with a small menu on your handy screen (download from the Logitech site), very near, far ... The autofocus really seems to work. I had read before buying, as the slightest movement went wrong: a hello, a nod ... I do not have that problem here. The eye of the cam follows me, no jerky movements. Maybe because my motherboard is HD? The basic hardware in your computer seems important. I am therefore delighted with this webcam. To install, your computer recognizes it immediately (there is no installation cd) but if you want to have the small software for personal settings (handy) must go to the Logitech website and download .This is not very hard to do and we must not reference license or password or otherwise. Just recognize your webcam, click and follow the instructions.
