Document cameras provide sustainable technology solutions for education that will remain useful for many years. They are broadly applicable to most classrooms, easy for teachers and students to use, and easy to integrate into lessons. Document cameras reduce the need for paper copies and textbooks while allowing visual content like documents, 3D objects, and experiments to be displayed on a large screen. This benefits both teachers, by making content easier to share, and students, by helping them to better understand and visualize lessons.
