Casinos employ elaborate surveillance systems that allow security personnel to keep watch over the entire casino. They monitor every table, window, and doorway with cameras. They can be adjusted to focus on patrons who seem suspicious. The video feeds are recorded so that a casino can investigate any suspicious behavior. A casino also monitors the payouts of its slot machines, with the information coming from the computer chips inside the machines.
