With a cheap HD webcam, you can stream videos across the Internet. You can also use the webcam to record video in the same way that a digital video camera can. Most have a built-in microphone, so you can record your voice. This makes it easy to create your own video podcast. The best HD webcam feature is the one that allows your far away friends to see you while you chat with them. With special software, you can even use your webcam as a security device. HD webcams come in all shapes and sizes, from standard ones that clip onto your monitor, to cute cartoon characters.
