Security in Casinos
There is no doubt that gambling moves a lot of money, especially since it is legal in most of countries and everything is fully controlled. Casinos and gambling halls have stopped being clandestine and have turned to the "good" side of the profits, which has caused many dark interests to disappear. But there is a lot of money, there may be competing interests, and security must be absolute, to prevent this from becoming a real problem. Casino managers have realized this, and are increasingly thinking about security.
In fact, the security of the casinos is more and more exhaustive, and not only because of the fact of controlling that there are no altercations, or the possible robbery attempts that may occur in a place where there is so much money. Also taking care of the players themselves, who could sometimes use cheating methods to obtain large profits. Given this, casinos can expel any player who thinks they are not playing fair. A lot happens with card counters in blackjack, they don't even need computer equipment or anything like that, they do it all upside down.
You may think that this method is as good as any other to play, but the casino tends to think that its advantage is nothing to these types of players, and it is better to expel them before they plunder your winnings. That is why there is always security in these gambling halls, at various levels in addition, from "plainclothes" agents who control these players at the tables and make sure they do not cheat, to the security cameras and the control that is carried out from central, where all the images arrive and are examined, passing of course by the obligatory presence of "gorillas" to avoid any altercation that could happen.
Casino security has not always been so important. Before, the number of people in charge of it was minimal, because it was an “extra expense”, or at least that's how the owners of these gaming rooms saw it. It was with the understanding that they could prevent large-scale robberies or losses of large sums of money that they decided to bet entirely on current security systems. Technology also helped, and now, with high definition cameras and even face recognition software, any casino can know who is playing there, and if they are an unwelcome visitor, kick them out.
