One of the underlying ideas behind the TV show “The Prisoner” was something called the Panopticon
https://en.wikipedia.org/wiki/Panopticon
Excerpt:
“The concept is to allow all prisoners of an institution to be observed by a single security guard, without the inmates knowing whether or not they are being watched.
Although it is physically impossible for the single guard to observe all the inmates’ cells at once, the fact that the inmates cannot know when they are being watched motivates them to act as though they are all being watched at all times. They are effectively compelled to self-regulation”
