A casino is a place where people can play various gambling games with the chance of winning money. It is usually a part of a larger hotel, entertainment complex or gambling cruise ship. It may also be a separate building or room. Unlike other types of recreational facilities, casinos offer an opportunity to win money through random chance, rather than through skill. In most cases, the odds of winning are mathematically determined by the house and are called the “house edge.” Casinos invest a lot of time and money in security to prevent cheating and other criminal activity.
Modern casino security is typically divided into a physical security force and a specialized surveillance department. The latter operates a closed circuit television system, often nicknamed the “eye in the sky,” that allows surveillance personnel to view all activity in the casino through one-way glass from a control room. The cameras can be adjusted to focus on certain suspicious patrons and can record events for later review.
Something about gambling seems to encourage people to try to cheat or steal in order to win. That’s why casinos spend a lot of time and money on security, especially in areas that are most popular with gamblers. Many casino security measures are relatively obvious, such as using the color red to discourage players from making excessive bets or taking too long breaks. Other more subtle security features include the use of uniforms that are easy to identify, and regular routines (such as shuffling cards or dealing a hand) that make it easier for security to spot unusual behavior.
