This is a great little USB web cam for very little money. When testing a dozen or so different web cams, I found this the easiest to use and the least expensive.
This cam does not come with software, and , autofocus, and subject tracking. It is fixed focal length and focus.
I found the lack of software to be a plus, as most all webcam software borders on being malware with its invasive and obnoxious effects on Windows.
This camera worked out of the box on standard Windows camera drivers, and for simple web conferencing, it is great. I have used it with Skype and works really well ain't had a problem yet
If you need a good basic, generic, USB webcam and don't want to shell out nearly 30 for a good one, give this great camera a try. it looks like a expensive camera.
