A casino is a place where people can play different games of chance. These can be slot machines or table games, such as baccarat and blackjack.
A lot of money is involved in a casino game, so casinos spend a great deal of time and effort making sure their players are safe and secure. These measures include elaborate surveillance systems, security cameras in the ceiling and specialized personnel watching over every table and slot machine.
The most obvious measure of casino security is to make sure no one steals from the house. This can be done by having dealers focus on their own table and spotting any suspicious behavior. It can also be done by having pit bosses watch over the whole floor.
There are also rules of conduct in the casinos, such as making sure players keep their cards visible at all times. This is a good way to catch cheaters who use their cards as weapons or try to swindle others.
Another important measure of casino security is to make sure no money is left on the table after a game. This is because a large amount of money makes people more likely to try to cheat their way into a big jackpot.
It is also common for casinos to have a closed circuit television system, known as the “eye in the sky.” This allows security personnel to view the entire casino from above. They can also adjust the camera to look at certain patrons and monitor their movements.
