Just about every new laptop purchased today is bundled with a built-in web cam. It’s a great accessory for video conferencing, but there are also plenty of other useful things to do with them. This tutorial will demonstrate how to turn just about any web camera into a security camera which will capture any movement it sees using motion technology. No extra components or tools required!
