I worked in Las Vegas casinos for almost 20 years. It was not until I reached upper level management that I was privy to any of the "Cam Shots that happened. You must understand that most of them are never seen by anybody because after a short time (usually 24 to 48 hours they are erased and the tapes reused. They are not reviewed unless there is a very specific reason to do so. HOWEVER:
On rare occasions Security would invite me to look at some particularly interesting tapes. I remember one that was of a gal in the hallway of one of the upper floors, naked and masturbating vigorously. I was always sure that she was doing it just for the security guys who might be watching!. Enjoyed it quite a lot, actually.
