Casinos tend to be confusing places, especially to the first-time visitor. There are cameras hung from the ceiling, dealers and pit bosses everywhere, and you’re not likely to find many signs to help you get around. Luckily, most casinos have security systems to protect their assets and keep their patrons safe.

When you play in a casino, you’re essentially playing against the house. The house edge is the average profit that the casino makes from a given game. While blackjack, craps, and roulette have the lowest house edge, baccarat has the highest, at 1.06%. It is important to remember that the house edge is designed to maximize the casino’s profits.

To combat this problem, casinos use elaborate surveillance systems to keep an eye on all patrons. These cameras are mounted in the ceiling and monitor every window and doorway in the casino. These cameras can be adjusted to focus on any suspicious patrons. The video feeds are recorded so that they can be reviewed later. Additionally, computer chips are used to randomly determine the payouts on slot machines.

Casinos also have strict rules about personal electronics. No cell phones are allowed inside. They are not allowed to be used while seated at a table. Moreover, most large casinos have thick walls that block cell phone signals. If you want to use your cell phone, you must walk outside the casino to receive a dial tone.
