A casino’s security measures vary, depending on the type of games and the number of players. Some casinos have catwalks suspended from the ceiling to allow surveillance personnel to view the floor. The glass is one-way, so surveillance personnel can watch what happens on the casino floor. These casinos are more likely to offer security and surveillance, so they should have the necessary tools to protect their customers. In addition, they should have video cameras installed throughout the casino.

A casino must know the house edge and variance in order to make a profit. The variance tells them how much cash to hold back for the event when bad luck strikes. These calculations are done by computer programmers and mathematicians, known as gaming mathematicians. Most casinos don’t have the expertise in-house to do this work. Instead, they hire professionals to do the work. There are a lot of people who are involved in this task.
