While you can get away with using the built-in webcam on your Macbook or PC laptop, you'll typically do better with a professional webcam specifically designed for streaming. There are several factors to consider when choosing the best webcam for streaming, including cost, resolution, focus, zoom and compatibility with your computer. You can usually find a good webcam that will do the job in the $50 - $100 range on Amazon. The best webcam brands are Logitec and Razer.
