This guide lists most of them plus the interesting new models and the current top ten , with reviews and up to date prices. The latter works best if you've got the bandwidth, from say cable modems and Intranets , but you can still happily do it with a standard modem. This site will endeavour to show how to get the last bit out of your bandwidth, and also how to use other video equipment especially still cameras and Digital Video Recorders. Software is also reviewed and rated. Most of the packages are for Windows PCs, although you will find some Linux and Apple flavours.
Most new cameras have a USB connector.
PCI gives the fastest screen refresh, called frame rate, frames per second , or fps , but costs more and requires opening the computer. Avoid cheap printer port cameras with poor fps. At the moment you can't use a Firewire Digital Video Recorder as a webcam. All you can do on the computer, with the right 1394 card, is edit video and make AVIs, which is fine just for video email. And video email is what you do if your real-time internet video gets too jerky and starved of bandwidth.
