With modern technology, operators can oversee huge areas of e.g. a gaming floor while at the same time being able to open as many “virtual PTZs” as needed to zoom in into details.
Next generation casino surveillance: Surveillance Managers
Dallmeier, German manufacturer of video security technology, highlights the importance of casino surveillance and urges surveillance managers to adopt a new era of technology.
Are 360° camera systems an alternative to PTZ?
Even if it is a bit hackneyed, the alleged Henry Ford phrase “If I had asked people what they wanted, they would have said faster horses” still illustrates very clearly what happens when you rely on existing technologies and do not look to the future. Ignoring progress or not actively updating knowledge on a regular basis is a comfort trap in which many casino surveillance managers find themselves today. Surveillance managers in casino operations must make the impossible possible on a daily basis. They are responsible for preventing and resolving a wide variety of events and incidents, from accidents to organised cheating in gaming operations to brawls. On top of that, they must meet the ever-increasing regulatory and occupational health and safety requirements. Although there is of course no clear mathematical
correlation, every second a perpetrator has more time to disappear, the probability of being caught decreases exponentially. Surveillance managers must therefore solve incidents as quickly as possible. For this, an optically high- resolution overall view is incredibly important as it enables the details of an incident to be traced exactly.
52 OCTOBER 2022 Pan-Tilt-Zoom (PTZ) Technology
Many surveillance managers still swear by the so-called PTZ systems in the casino however they have serious disadvantages. They reduce the observed – and the recorded – events to the section selected by the operator. Contexts become increasingly unclear the higher the zoom factor, and everything outside the PTZ zoom escapes the recording and is therefore not available for exploitation in court. PTZ systems do not record any areas outside the selected pan-tilt-zoom range. This means that all events outside these areas are neither available for use in court nor for playback. And – increasingly important – video analysis and PTZ are completely mutually exclusive since unaltered image correlations are of course required for meaningful image analysis.
Are 360° systems an alternative?
More and more users are recognising these technology-related disadvantages of the “PTZ system”. As a result, they try to overcome them by using some form of 360° camera hoping to reduce the number of camera systems required and in parallel increase security. And this is where it starts to get a bit complex
