A bstract — A low cost, single‐operator, four‐camera, closed‐circuit television system was developed to teach dental technology to large classes (120) of second and third year (preclinical) undergraduates. Its use permits demonstrations to be conducted, recorded and played back, with no electronic knowledge, little training, and a minimum of preparation and assistance. The field of view is from above the demonstration table, and is selected by pushbutton in the size range 30 cm × 20 cm down to 3 cm × 2 cm. The system has many advantages, few disadvantages, is reliable in operation, and is acceptable to students.
