A casino is a building where people can gamble and play games of chance. The games typically have mathematically determined odds that ensure the house has an advantage over the players, which is called the house edge.
Besides gambling, casinos can also offer other activities such as dining, entertainment and business facilities. These amenities can help lure gamblers to the casino and keep them there longer, and in turn, give the casino more money.
The primary concern of modern casino security is preventing criminals from taking advantage of the environment and exploiting human weakness. This is accomplished by a variety of techniques, including patrolling the property and monitoring closed circuit television surveillance. Other methods include a specialized armed security force, which responds to calls for assistance and reports of suspicious or definite criminal activity.
Security at a casino is a complex task and requires close cooperation between the physical security force and the specialized surveillance department. These personnel work together to monitor the activities of all guests and protect casino assets from theft or other forms of criminal activity.
In addition to these more traditional forms of security, modern casinos employ catwalks in the ceiling above the gaming floor so that surveillance personnel can observe the activities from a distance. They also use a combination of technological measures to prevent crime, including video cameras and sensors that detect motion or other abnormalities. Combined with routines and patterns in the behavior of players, these techniques are very effective at preventing crime.
