■ Picture quality. A key indication of quality is resolution. The resolution of most webcams is either 320 x 240 or 640 x 480. In general, higher-resolution webcams produce better images. ■ Speed. Most webcams connect to a computer through a standard USB 1.0 port, but some models connect through higher-speed ports. FireWire and USB 2.0 generally provide better quality than USB 1.0 webcams, because they do not have to compress the image to transfer it to a computer. A computer must have a FireWire or USB 2.0 port to accommodate these devices. If your computer doesn't have one of these ports, you can add a FireWire or USB 2.0 card. Camcorders generally have higher-resolution imaging chips and better lenses than webcams. Most also have a zoom lens, which allows greater flexibility in positioning the camera and greater control over framing the shot. Also, FireWire camcorders are designed to be plug-and-play devices. If your computer has a FireWire card or port, you can plug in the device and begin to use it.
