In any casino around the world, there are very likely to be more cameras dotted around the place than people. This is to deter any potential wrongdoers, and to be able to prove the wrongful acts of those that do manage to commit them. By having so many cameras, then even if the security guards are not able to survey all of the different camera feeds constantly, they can use the footage to ensure that casino criminals are brought to justice, and sometimes the threat of using this footage against the baddies can draw out admissions of guilt before the law enforcement officers are brought in. Though this is a recent evolution, it’s safe to assume that any casino you find yourself in will be watching you wherever you are, and so it’s best to resist any temptation to bend the rules.
