If you’ve never gambled in a casino, you might be surprised to know that there are numerous ways to avoid committing a crime in this setting. Fortunately, casinos have elaborate surveillance systems that allow security personnel to watch every corner of the casino. Video cameras mounted on the ceiling of the casino watch every table, window, and doorway. These cameras can be adjusted to track suspicious patrons and record video feeds for later review. Computer chips in slot machines determine the payouts and ensure that patrons aren’t abusing the game.

Many casinos have become more technologically advanced since the 1990s. Video cameras and computers now routinely monitor gaming action, while casinos also have built-in microcircuitry that allows them to track wagers minute-by-minute. Roulette wheels are also regularly monitored to determine statistical deviations. Several casinos have also introduced enclosed versions of these games that eliminate the need for dealers. Players can bet by pressing buttons, rather than having to stand in line to speak with dealers.

In addition to the modern security features, casinos use other tricks to attract gamblers. Some casinos have catwalks suspended above the casino floor. This allows surveillance personnel to look directly at patrons. The glass is often one-way so that thieves cannot see inside the casino. However, a casino may be less secure than one would think if a burglar was waiting in the casino lobby. While these steps are effective in preventing theft, the crime rate still remains high.
