Abstract: Use of the vidicon tube, helical-scan video-tape recording and solid-state circuitry has brought closed-circuit television within the budgetary reach of even small schools. New models of equipment are continually being offered; specifications and prices vary widely, with no clear set of criteria for selection. The technical characteristics, typical applications and initial operating costs of the equipment are discussed, with emphasis on cameras and recorders. Cameras using vidicon, Plumbicon and image-orthicon tubes are compared as to image quality, ease of operation and maintenance and cost. The comparative features of recorders include tape-scanning format, compatibility between machines, editing, color capability and acceptability of tapes for broadcast.
