Sharper insight on Internet Protocol-based video surveillance
Evolution of analytics and image quality makes IP-based video security a big win for casino owners
Casinos present unique challenges when it comes to video surveillance.
With crowds of people, both guests and staff, on the premises day and night, and money, chips and cards changing hands at a rapid rate, security is something every casino manager knows has to be considered wisely.
The costs associated with monitoring guests, as well as employees, can be significant, and many casinos still have older analog-based security systems that have been in place for years. Those systems typically require substantial human interaction with on-the-ground personnel which represents a high operational expense. Digital IP-based (Internet Protocol) video surveillance cameras with on-board intelligent analytics can reduce costs and streamline operations.
In addition to higher overall resolutions, an IP video infrastructure can make security workflows more efficient and bring new business intelligence features to operations as well. Imagine having your security cameras working as your eyes and ears on the floor and notifying you not only when security issues occur, but also when lines are getting too long, or extra staff is needed. By providing business analytics, such as people counting, resources can be better allocated to determine if there’s not enough dealer coverage on the floor, when there are large lines at the cage or which games are getting the most footfall. Business analytics can be an invaluable tool that helps casinos when funding improvements. In-camera security analytics can detect specific types of motion, such as loitering, appear, disappear and directional detection, that can provide alerts to suspicious activity. Audio analytics can detect glass breaking, gunshots and screams.
These technology advances in analytics, both for business intelligence and video surveillance, make a strong case for those seeking to streamline operations by upgrading to a new IP-based video infrastructure.
THE WISENET ADVANTAGE
30 frames per second (fps) is the mandated minimum framerate for gaming surveillance since security personnel need to clearly see and/or freeze the motion of hands, money, chips and cards when reviewing an incident. In addition to single sensor cameras, highly cost-effective multi-sensor cameras are now available that can deliver 30fps and even 60fps video. Our Wisenet PNM9080 multi-directional camera is the only multi-sensor camera on the market that can operate at 60fps and can capture motion in low-light environments.
Often, ambient background lighting is low with scattered bright LCD displays which cause cameras to try and compensate for these widely varying light conditions. This is where a feature like Wide Dynamic Range (WDR) becomes increasingly important. WDR captures multiple exposures of the same image and combines them into a resultant image that more closely replicates how our eyes see in variable light conditions. However, switching on WDR for improved low-light and bright light performance impacts the effective framerate, typically cutting it in half, since extra frames are now storing multiple exposure information. In this scenario, a 30fps camera becomes a 15fps camera when utilizing WDR. The answer then is 60fps cameras to deliver a crystal clear WDR image while still providing the gaming commission’s 30fps mandate to precisely capture motion.
The Wisenet X series cameras have up to 150dB of WDR which can mean the difference between clearly seeing a face or not. It’s possible to purchase analog cameras capable of recording 60fps with WDR, but these cameras and supporting infrastructure are typically much more expensive than their IP counterparts, typically provide lower performance and do not offer any of the analytics discussed above.
Storage may become a concern when considering higher frame rates and larger images. By using the latest H.265 with Wisestream II compression, bit rates and file sizes are kept at a manageable level. Wisenet cameras are also capable of reducing the framerate when there is no motion detected, which reduces the amount of total recorded, unusable video.
The use of the PTRZ (pan, tilt, rotate, zoom) function can be an important consideration for casino operations as well. The ability to change the orientation of tables or foot traffic routes is enough of a disruption without the added expense of hiring an installer to manually adjust camera positions. Our Wisenet XNV-6085 (outdoor) and XND-6085V (indoor) PTRZ cameras can be adjusted remotely in a few minutes ensuring minimum disruption to game play and maximum flexibility. These cameras also utilize our extraLUX low-light lenses and technology enabling them to deliver color pictures in the darkest environments.
There are more reasons than ever to streamline casino security operations with the evolution of intelligent cameras that provide not only security, but business intelligence as well.
