7.13 The Eye in the Sky

Historical — Surveillance

“The Eye in the Sky” is the casino industry term for the overhead surveillance system of cameras and monitoring equipment positioned above the casino floor. The term became widely used during the corporate gaming era of the 1970s as casinos installed comprehensive CCTV systems to deter cheating, monitor employee conduct, and prevent skimming. Modern eye-in-the-sky systems include high-definition cameras with pan-tilt-zoom capability, facial recognition software, and recording systems that capture all gaming activity.

In practice

The eye in the sky is the primary tool of casino surveillance operations. In Asia, where baccarat dominates, surveillance systems are optimized for monitoring card games and detecting edge sorting, card switching, and dealer collusion.
