If you're considering buying a document camera then this guide can help you find the ideal one for your needs. As an educator, or student, these can be very helpful devices to bridge the physical and digital divide when learning.
At its most basic, a document camera is a small and maneuverable digital camera that can live record, up close, what you're doing. That makes it a great way to show an experiment to the entire class, for example. As a teacher, you could video what's happening and have that thrown to a big screen for the entire class to see, close-up and in detail.
