Megapixel cameras in demanding gaming environment
The action is fast and the stakes are high. Fortunes are won or lost on the turn of a card or a roll of the dice. It's where the rush of adrenaline meets the hope of beating the mathematical odds. And it's the perfect application for IP Video surveillance using powerful MegaPixel cameras.

Gaming is not just fun, it's big business - and as a business, it depends on video surveillance to keep the casino tables profitable. The need to see the details in a video image - a stack of chips or the index on a playing card - makes gaming an application that was practically waiting for the invention of MegaPixel cameras. The latest MegaPixel cameras have no problem following the fast action of a casino game and capturing the video in precise detail for analysis or to confirm a jackpot win. And new developments, notably the emergence of the H.264 compression standard, are paving the way for wide-scale implementation of MegaPixel cameras in the gaming market by making issues of storage capacity and bandwidth perfectly manageable. The expanding capabilities of MegaPixel cameras are poised to take the gaming industry by storm, starting at the Native American casinos and coming soon everywhere from the Las Vegas strip to Macao.

One of the early adopters of MegaPixel technology for gaming applications is The Lucky Eagle Casino in Southwest Washington State - a state of the art video surveillance solution designed and implemented by North American Video employing MegaPixel cameras from Arecont Vision. Miguel Grijalva, Director of Surveillance at The Lucky Eagle Casino relies on Arecont Vision's MegaPixel cameras to improve his staff's ability to view and identify critical information at the gaming tables. "The new MegaPixel cameras were installed in order to improve image resolution issues we were experiencing with conventional analog cameras," says Mr. Grijalva. "It is important that our surveillance operators can clearly see the indexes of the cards. We need to unmistakably view suits and ranks and be able to distinguish between a heart and a diamond. The analog cameras were not picking up enough of the detail. The MegaPixel cameras provide the resolution we need to track and verify what is actually happening at our gaming tables."

The ability to view additional details is the result of the additional resolution provided by a 2 MegaPixel camera (1600 x 1200 pixels) compared to a conventional VGA image (640 x 480 resolution). The cameras being used at The Lucky Eagle Casino are AV2100M 2 MegaPixel cameras from Arecont Vision. They offer a frame rate of 24 fps (frames per second), a resolution of 1,600 x 1,200 and a minimum illumination of only 0.1 lux @F1.4. The camera is part of Arecont Vision's MegaVideo line that leverages proprietary patented technology to help alleviate the cost and frame rate shortcomings often associated with multi-megapixel camera systems.

The MegaPixel cameras at The Lucky Eagle Casino were installed to supplement - rather than replace - the analogue cameras already installed. Because the high-definition resolution of the MegaPixel cameras allows wider shots, a single MegaPixel camera is used per table. The analogue camera systems are still being used for high frame rate (ie, 30 frames per second) recording purposes and for more fluid motion. The MegaPixel IP cameras are recorded at 5 frames per second, thus allowing for reduced storage requirements. "The frame shot is the same as the analogue camera frame shot, but the clarity is several times better. If a guest had a full flush, we can go back and readily confirm it because the picture quality is so excellent," Mr Grijalva says. There are currently fifteen AV2100M (2 megapixel) cameras being used at the Lucky Eagle Casino to monitor 20 table games, 725 slot machines and five poker tables.

A built-in electronic pan/tilt/zoom (PTZ) function is also beneficial in live monitoring or to review footage. The capabilities enable the casino to spot unusual activity or an instance of suspicious behaviour or cheating, as well as ensuring that employees comply with procedure. Transitioning to a hybrid system (combining analogue and digital technologies) allowed Casino Surveillance operators to use the new cameras without additional training.

"As demonstrated at the Lucky Eagle Casino, MegaPixel cameras offer significant imaging advantages and can be very cost-effective when used judiciously on any video surveillance system platform," says Cynthia Freschi, president of North American Video, the system integrator that installed the video surveillance and security system at Lucky Eagle Casino, and later enhanced the project with MegaPixel cameras.

In the foothills of California's San Jacinto Mountains is another gaming application of MegaPixel cameras at Soboba Casino, which features 2,000 slot machines, more than 20 table games, three restaurants, a 12,000-seat entertainment pavilion and a huge sports lounge.

Joe Balistreri, CEO/president of Vision Surveillance handled the systems integration when Soboba Casino recently upgraded from analog to digital, using a Nice Systems DVR/NVR system along with AV1300 MegaPixel cameras from Arecont Vision. Mr Balistreri chose the cameras because "the resolution and clarity far surpass any analogue camera."

"I looked at a few different cameras at security trade shows. We found that the Arecont cameras were the easiest to use and had the best picture," Mr Balistreri says. The AV1300 is a 1.3 MegaPixel camera from Arecont Vision that offers a frame rate up to 30 fps (frames per second) and a resolution of 1,280 x 1,024.

The cameras enable observers of table games to easily see the cards on the tables and make no mistake if a card is a king of hearts or a king of diamonds. "That kind of quality goes a long way, and observers are able to do their job better," Mr. Balistreri says. "The picture is so clear that you can see the cards and absolutely make no mistake on the suits or the face values. Anyone who looks at video from these cameras is blown away by the clarity of the picture."

A third Native American Casino - Chumash Casino Resort in Santa Ynez, Calif., 35 miles north of Santa Barbara - has installed 100 MegaPixel cameras from Arecont Vision to watch their security-sensitive locations such as table games, cashiers' windows and kiosks. Mark Meske, Director of Surveillance and Compliance at Chumash Casino Resort, saw the MegaPixel cameras at a trade show and was amazed: "We did the research and found that they have six times the clarity of non-HD cameras." Casino personnel view the cameras on 70 monitors in a 1,500-square-foot monitoring center to watch for spills in the cash cage or potential procedural violations in the table games. Storage requirements for the MegaPixel system are met by a 500-terabyte cluster storage array that retains video for 14 days minimum for the security-sensitive areas.

Even with the outstanding capabilities provided by MegaPixel cameras, bandwidth consumption has remained one of the most prevalent issues for large scale deployment in casinos. It takes a lot of bits and bytes of data to create a Digital Video image - so much so that video data could quickly overwhelm existing network infrastructure and eat up storage capacity. It takes even more data to create real-time motion video with high-definition quality using MegaPixel cameras. But with improved compression technology - specifically H.264 - gaming facilities can now dramatically increase the deployment of MegaPixel cameras with a high degree of cost-efficiency.

There have been several compression standards during the brief history of Digital Video - the most widely used in IP Video being MPEG-4 and JPEG. These standards have served the industry well - MPEG-4 for streaming media at a low bandwidth and M-JPEG to provide frame-by-frame images. However, as the number of megapixels increases with the need for resolution and higher frame rates, a new standard called H.264 will make it possible to compress video even more efficiently while maintaining resolution and low bandwidth. Using H.264 can provide 5 to 12 times greater compression efficiency on average compared to M-JPEG implementations.

A more complex H.264 encoding process takes more processing time and/or requires a more advanced processor in the MegaPixel camera, but is necessary for maximum savings of storage and/or bandwidth. For example, Arecont Vision has developed an FPGA-based hardware image processing chip that delivers 80 billion operations per second and only incrementally increases its camera pricing. The chip enables maximum compression in real-time. The standard ensures that any H.264-compliant decoder can "de-compress" the video. The complexity of decoding H.264 is similar to the complexity of decoding M-JPEG, so there is no greater CPU load when the video stream is decoded for display.

The great news for the gaming industry is that by using H.264-compliant compression, casinos can benefit from the best of MegaPixel technology -- image size and resolution as well as manageable bandwidth and storage requirements. Alternatively, if they are willing to go to a lower frame rate, they can save more money on storage, an expensive component.

To keep the games fair (ie, to maintain the house advantage), surveillance has been a huge part of the gaming industry from the beginning, when security personnel watched the games from catwalks in the ceiling above the casino. Only the technology associated with surveillance has changed. As the video surveillance market has evolved, from black-and-white to color, from analog to digital, from VCRs to DVRs to NVRs, the gaming market has embraced each technology and put it to good use to watch the casino for thieves, cheats, card counters and others seeking to tip the house advantage in their favor. Widespread use of MegaPixel cameras is the next step in that evolution. And as the technologies surrounding MegaPixel cameras continue to evolve with developments like H.264 compression, we can expect more casinos to incorporate this advantage into their security systems.
