Just thinking the other day, do the internal sensors of Starships continually monitor every part of a ship for security purposes or do they do this in Starfleet. There's two instances that can argue for and against the idea and the first is in Trek 3 TSFS where Kirk views a recording from Engineering where he sees Spock giving a McCoy a mindmeld but then there's at least one other incident in that episode of Voyager where Lon Suder murders that Crewman in Engineering but Tuvok doesn't think to check for any type of surveillance to see who might've been in Engineering at the time implying that none exists.
So is there or isn't there surveillance on Starships?
