External webcams, however, can be moved around and set up in different positions, allowing you to capture from a different angle, or set up to show off something other than what's directly in front of your computer. A computer's built-in webcam can't be moved, so you're stuck with a single camera position. Some even have noise-cancelling technology, so if you're streaming for an audience, this is definitely recommended. However, even a relatively cheap webcam can improve the resolution of your image, making for a better overall result, and what's more will generally come with a built-in microphone, which makes the audio noticeably cleaner and clearer for the audience on the other end. Macbooks and iMacs have their own webcams built in, so you might wonder why you'd need a dedicated webcam.
