A casino, or a gambling establishment, is a place where people can risk money on games of chance. Casinos are found worldwide and operate on a variety of business models. They can be standalone buildings, like the one in Monte-Carlo, or they can be built into hotels, like the Sun City Resort in Rustenburg, South Africa. Many casinos also feature top-notch restaurants, spas and other amenities to attract customers.
In order to prevent cheating and theft, which are common occurrences in casinos, a great deal of time, effort and money is spent on security. This includes both the use of cameras throughout the facility and, in some cases, having staff physically patrol the casino floor. In addition to this, many casinos have catwalks that allow surveillance personnel to look down on the table games and slot machines from above.
Something about the large amounts of money that are handled within a casino encourages patrons and employees alike to try to cheat or steal, either in collusion or independently. This is why most casinos spend a large amount of money and effort on security. This is especially true for the larger casinos in major cities, such as those on the Las Vegas Strip.
