We Know: Tips on Buying a Webcam What's a webcam? A webcam is a video camera attached to your computer. It transmits the images it sees to your computer which can then share the images to other computer users via one of several software programs available, including MSN Messenger and Skype. Some people, governments, and companies choose to use webcams to make live video imaging available to visitors through their website. Many zoos and cities have webcams whose images you can see on their websites. Some people use webcams for security purposes, using them to monitor their home or office. When shopping for a webcam, be certain that it's compatible with the operating system of your computer. Most webcams now use USB ports, so if your computer doesn't have a USB port, you may be able to use a USB to PS/2 converter.
