Casino security starts on the casino floor. There are cameras above every table and in every doorway. These cameras are designed to identify cheaters and watch the casino workers. Dealers and pit bosses also monitor the tables for betting patterns and suspicious patrons. Each employee has a supervisor who is watching them. These employees work in teams to prevent cheating and keep the casino clean.

Casino security is an extremely important aspect of any casino. Casinos spend large sums of money to keep their facilities safe. Many people forget to cash their chips or take them home, which makes it much harder for them to detect suspicious activity. Some casinos even employ surveillance to detect the difference between the chips and cash. Almost every casino has a loyalty program for its members.

As technology developed, casinos began to use computers and video cameras to supervise their games. One such technology is “chip tracking” – bet chips with microcircuitry embedded in them allow the casino to monitor wagers minute-by-minute. Routinely monitoring the roulette wheel is another common practice. This helps casinos determine how much variance occurs in a wheel, which could be a factor in winning.

Moreover, casino managers need to know how to calculate the house edge and variance. This is necessary to keep track of how much profit to be made and how much cash reserves to hold. This work is performed by computer programmers and mathematicians. In many cases, casinos do not have an in-house expert in this field, so they hire experts to do this task.
