These appear to be single-vidicon (striped faceplate) cameras (they may have used another photoconductive tube, like a Saticon). They would have been intended for school, industrial training, or cable TV systems. They would not provide a quality of picture much better than a home camera based on the same technology, except that some controls were brought out for adjustment of electrical focus and target voltage. Electrical focus was critical for resolving the color filter stripes to get good color balance. They also would have needed more light than the big 3-tube studio cameras to reduce motion smear.

The size is very likely smaller than studio cameras of the time (maybe about 50% in each dimension).

"ITV" on the lens probably means "Industrial TV"
