I would bet that there are much better cameras out there for a fiver. This camera has a very low frame rate, regardless of internet connection speed, which is easily its main fault. It will give you a headache after a couple of minutes. In 2010, that just won't cut it-feels more like something you found in your dads basement from 1990 or even earlier, and your trying to get an even older 8-bit computer to run it! I take no points away for not having sound, as it does state that on the box. It does work with Vista and Windows 7, but its so simple that it would be very odd if it did not. Save your money and buy something for double the price with a different brand, Im betting you will see a big difference
