Gambling is something that attracts people from all walks of life. Casinos offer an exciting way to gamble, with games of chance like slots and poker, as well as skill-based sports betting and other wagers that depend on knowledge of teams and players. In addition to being a great source of entertainment, casinos have also been shown to boost local economies.

There is much to love about a casino, from its free drinks and comps to its beautiful decor. But the truth is that casinos have become masters at using psychological tricks to keep you inside the building and gambling as long as possible. From the design of the gaming floor to the way they reward their regulars, they are constantly evolving and optimizing their systems to maximise pleasure — and profits.

As you can imagine, it takes a lot of people to run a casino. There are pit bosses, fraud experts and alert security personnel to name just a few of the positions needed to make sure that everyone is happy and safe. Casinos deal with large sums of money and there is always the potential for patrons or staff to cheat or steal, either in collusion or on their own. This is why many casinos have cameras throughout their facilities.

Elaborate surveillance systems give a high-tech eye-in-the-sky view of the entire casino and can be refocused to zoom in on suspicious patrons as they move around the facility. There are also patterns to the motions of casino game play – the way dealers shuffle cards, where they put their bets and the reactions of other players – which can help security identify any unusual activity.
