A camera of any brand or style. I always recommend a digital DSLR camera, however, a phone camera or digital point & shoot camera is fine as well. I just recommend that it be easy for your student to use and something he or she has already used before this class. I do not teach about the camera other than just the basics in this class. 

The teacher uses YouTube to show a few clips of videos to support the student's learning. The videos are embedded in a presentation created by the teacher via Spark/Adobe. Sometimes the videos are also posted in the classroom. No ads are shown during the clips. The videos are age appropriate to speak directly to the learner specifically about the teaching point.
