However, at the time, it took about 20-30 minutes for the cameras to warm up

Even modern equipment may require some time to reach a stable temperature. 20 to 30 min. seems reasonable.

20 to 30 minutes of warm up time does seem a bit long.

Yes, vacuum tube tech. Vidicon tubes were used in the cameras to pickup and generate images seen through the camera lens. On the other end of the system was the CRT...cathode ray tube that “painted” the image we watched on our 200# sets.

Vidicons were used into the 1980s.
