If you’re running the app on a laptop with a built-in camera, you don’t need anything else (besides a Web browser).
If you don’t have a built-in camera or just want a better picture, simply attach any external camera to your computer. Other than that, you just need any writing surface (a whiteboard, a blackboard, a flip chart, electrostatic sheets, or even a sheet of paper) and something to write with (markers, pencils, pens – anything!).
