As you can tell from the shape, it is designed for use with a laptop, plugged into the side and then twisted to point
at the user. However, I'm using it with a desktop (and my monitor lacks any handy side USB ports). I had to use
the included stand which doubles as a USB extension cable.
According to the box this does 1280x1024 pixels (real 1.3 megapixels), and says "Ready to use; no drivers to install".
That is usually a clue that you are dealing with a UVC webcam, and despite the "PC Only" label on the packaging, and
it works fine under Mac OS X (both camera and the microphone).
