The series itself is pretty very neat. You can get an idea on how surveillance in a modern casino works. This one talks about the surveillance department at Aria. I've never worked at a casino before so I don't know if anything is exaggerated or not, but still very interesting.

The video is more about cheaters and not about blackjack specifically but I feel people can get a kick out of it.
