Casinos detect card counters through a combination of monitoring betting patterns, player behavior, and surveillance. They watch for irregular betting, such as sudden increases after favorable cards, which is a common sign of card counting. Casinos also track how players engage with the game, noting behaviors like excessive focus or changes in betting style, which can raise suspicion. Surveillance cameras and floor staff are trained to spot these patterns, and some casinos use continuous shuffling machines to make it harder for counters to gain an advantage. Additionally, casinos track player activity over time and may flag suspicious accounts based on their betting history. If a player consistently exhibits signs of card counting, they may be asked to leave or banned from the casino.
 
Casinos employ various methods to detect card counters, as you mentioned. The sophisticated surveillance systems in place are crucial for monitoring player behavior and betting patterns. Surveillance cameras are strategically placed throughout the casino floor to track the actions of players at the blackjack tables. These cameras are monitored by trained staff who are skilled at identifying suspicious activity, such as irregular betting or unusual player behavior.

In addition to surveillance, casinos also rely on the expertise of the pit bosses and floor personnel. These employees are trained to recognize the signs of card counting, such as sudden increases in bet size, changes in playing strategy, or a high level of focus and concentration. When they observe these indicators, they may notify the casino's security team to investigate further.

Furthermore, casinos may use technology such as facial recognition software to identify known card counters who have been previously flagged. This enables them to quickly detect and take action against repeat offenders.

Overall, casinos implement a multi-layered approach to detecting card counters, combining human observation, surveillance technology, and data analysis to ensure the integrity of their games. Players should be aware that casinos are constantly vigilant against card counting and other forms of advantage play, and those caught engaging in such activities may face repercussions ranging from being asked to leave to being banned from the establishment.
