Leigh Sports Village Security In Safe Hands Of NVT's CCTV Transmission Solution
Leigh Sports Village Security In Safe Hands Of NVT's CCTV Transmission Solution

One of the biggest investments in public sports, recreational and educational facilities in the Wigan borough, Leigh Sports Village is a state-of-the-art 10,000 seat stadium complex. Aimed at renewing and extending facilities for sport, physical activity, education, health and leisure in the community, the Leigh Sports Village project has involved significant levels of regeneration and economic development and in addition to a home ground for both the Leigh Centurions Rugby League and Leigh Genesis Football clubs, also provides comprehensive leisure and educational facilities for the community. Securing the project's £83M design and construction is a Network Video Technologies (NVT), UTP Hybrid Video based CCTV transmission solution. Project planningFrom the outset of the project, the construction company oversaw all of the construction decisions on behalf of Wigan Council. From the project's inception, the security and safety of both staff and visitors was a top priority. Addressing this, the construction company appointed Tate Security Technology Ltd to manage all aspects of the installation of stadium security measures. Steve Hutchinson, Sales and Business Development Director at Tate Security, explains: "The Stadia Construction companies recognized our years of experience in the provision of stadia security and empowered us to work from the embryonic planning stages of the project. Working ‘off plan' allowed us to use our experience to predict visitor flow around the facility, and to fine-tune things such as camera positioning at this early stage, to gain the maximum and most effective scene coverage.""We were responsible for all aspects of security implementation at the stadia, including the turnstiles and access control. However, the keystone of the whole security plan was a comprehensive CCTV surveillance system, comprising over 60 cameras, including an onsite control room.""All modern stadia security is required to conform to guidelines as set out in the stadia industry manual known as the ‘Green Guide'. This states a variety of required operational criteria, including specific video quality, coverage and performance of the CCTV network on match days.""During the planning stages, we originally looked at implementing an end-to-end IP system at the site, as during non-match days, the images from the stadia would also be monitored at the Wigan Town Hall upon their 'Borough Central Watch' but we encountered a number of issues with this solution. The unobtrusive structured cable network element of an IP system was just what we were looking for, for installation within the minimalist structures of the stadia, but to conform to the Green Guide's 25 Frames per Second (fps) standard for match day coverage would have presented a significant challenge. Also, a totally IP system would have required the use of a comparatively expensive IP camera solution, including network switches every 90 metres, to amplify the signal, whilst the alternative fiber network proved far too costly due to the high-cost of the cable and specialist installation requirements."NVT is the key Tate was responsible for security implementation including the turnstiles and access control "At this point, we introduced the idea of employing a NVT based UTP Hybrid Video transmission solution, and with comprehensive technical guidance from NVT, we decided this would present the best solution. Harnessing NVT technology afforded a minimal and easy to install cable network, with Cat5 UTP runs installed in the underground ducting to the stands. Deploying analog video also meant that we could realize real-time (25fps) fiber-like images on match days, with the added bonus of still being able to encode the video and transmit images via the council's private fiber network, for off-site monitoring during the week - a real Win-Win scenario."Completed in mid 2008, the new stadia included service infrastructure ducting into which UTP Cat5 cable runs were installed. "NVT's inherent interference rejection capability meant we could transmit high-quality images in the same service ducts as other stadia services, such as the stadia's high-voltage power cables and communications network, without any worries about picture interference," adds Steve. "NVT's interference immunity is particularly advantageous in a stadia environment due to the large amount of radio interference from the stewards radio network, and TV and radio broadcast equipment.""Images from the system's cameras are transmitted via NVT NV-216A-PV and NV-218A-PVD video transceivers over 4-pair Cat5 spurs, to patch-panels housed beneath each stand. Video signals are then transmitted via 50-pair Cat5 UTP bundles back to the equipment room, situated adjacent to the bespoke control room. Here five NV-16PS13-PVD Power Supply Passive Receiver Hubs feed the incoming pictures to a camera switching matrix and the latest DVR technology. The balanced and consistent video composition required by modern DVR's is delivered via the NVT transmission, further helping to reduce installation headaches and the overall set-up time of the system."In addition to providing quality video to the control room, NVT's Power, Video and Data (PVD) technology has also afforded low-voltage power to be supplied to both static and PTZ cameras around the ground. Obviating the need for individual fused spurs to be installed at each camera point, this again saved time and money on the overall cost of the CCTV installation. System performanceMatch days can see the ground filled to capacity with both home and rival fans, eager to see their teams in action. The keystone of the whole security plan was a comprehensive CCTV surveillance system, comprising over 60 cameras  Managing the flow of fans in and out of the ground is a critical safety concern in modern stadia, and one of the major roles of the surveillance system at Leigh Sports Village. High-resolution images are used to continually monitor the flow of fans throughout its concourse, walkways and through turnstiles, both internally and externally. Information on ‘flow rate' (density, velocity and flow relationships for closely packed crowds) is relayed by the dedicated radio communications network, to the stewards controlling safety at the turnstiles and gates. Should the flow rate rise in a particular area, stewards can then address and manage the flow, ensuring the safety of fans at all times."Match days is when the unrestricted resolution bandwidth and quality of the NVT UTP transmitted camera images really benefits the club," explains Steve. "Although the Leigh Centurions Rugby League Club's fans have an exceptional record, being able to remotely pinpoint any trouble causers in the crowd ensures it stays that way, and should an incident occur, high-resolution recorded images permit easy identification of any individuals involved. Identification of individual crowd members through high- resolution images is an integral part of the standards for stadia CCTV, as set out in the Green Guide, and employing NVT UTP Hybrid Video transmission has been integral to this installation meeting those defined standards."During the week, camera images are used to secure the ground, with surveillance monitoring switched to the council's control room at Wigan Town Hall. "This kind of flexibility is invaluable to the club and means economical monitoring is made available in addition to high-quality archived recordings, easily and instantly accessible onsite," adds Steve. "Whilst match days see the system record at 25fps to fulfill Green Guide criteria, during the week this is reduced, saving valuable digital storage space but still providing crystal-clear, real-time live images to the Wigan control room via off site Fiber Optic Transmission." Harnessing NVT technology afforded a minimal and easy to install cable network  Even mid-week the stadium is a hive of activity, with offices within the complex let to local businesses, and events and seminars held at its function rooms, all in addition to a special needs learning center. CCTV coverage also provides an invaluable security tool in the club shop that sells football and rugby merchandise throughout the week. NVT UTP Hybrid Video transmission also provides future-proof systems expandability at the stadium, ensuring any future camera additions can be easily integrated via multiple ‘spare' UTP pairs included in the initial Cat5 cable network by Tate Security. This will definitely be the case when the site expands to include new leisure and specialist retail facilities, restaurants and bars.Steve concludes: "Effective systems expandability is essential at the stadium, as it continues to attract more visitors and diversify its activities, both in weekend events such as pop concerts and boxing matches. New cameras may need to be added to cover as yet unused aspects of the site, or additional coverage may be deemed necessary for existing cameras, such as upgrading static cameras to PTZ, in which case it's an easy process to simply use one of the ‘spare' UTP pairs to supply PTZ telemetry data. With the flexibility of NVT UTP transmission, we can locate cameras in ideal positions to gain the most desirable scene coverage, which is not always possible when using cumbersome coax cable. Whatever the scenario, our economical, NVT based CCTV system at Leigh Sports Village is set to provide flexible, high-performance security, site management, and health & safety surveillance for many years to come."

MOBOTIX Provide Video Technology At Europe's Largest Man-Made Mountain
MOBOTIX Provide Video Technology At Europe's Largest Man-Made Mountain

Mobotix cameras can withstand the harsh conditions  It’s important for manager Wolfgang Schwarz’s employees to concentrate and be vigilant at all times. Have all the passengers up at the start correctly put down the safety bar? If so, their descent down the toboggan run at Monte Kaolino in Hirschau will begin at the push of a button. The employee’s gaze immediately shifts to the images coming from another video camera as just a few seconds later, another bobsled hurtles towards the finish at 40 kilometers an hour. The driver is supposed to brake before he reaches the bottom. If he doesn’t do so, there is a short clicking sound and the system automatically reduces the speed of the sled. MOBOTIX IP cameras have large parts of the toboggan run firmly in their sights. The cameras record information every time a sled starts and crosses the finish line. ”This shows that we’re documenting events objectively, should a guest ever complain,”says Schwarz. The Mountain is Calling: Ski in Your Swimsuit "There were a few crucial points that showed us that MOBOTIX IP systems are the only ones that can handle difficult challenges" The giant white mountain in Hirschau near Amberg is really quite a rarity. It is one of the highest man-made peaks in Europe where 30 million tons of quartz sand has been piled 150 meters high. The mountain sparkles as snow-white as a distant Alpine peak, even in the sizzling Summer heat, and it offers brilliant views as far as the Czech Republic. Created from demolition work, Monte Kaolino’s rare attractions attract hundreds of thousands of outdoors lovers every year. Skiers and snowboarders wearing bikinis and swimming shorts, sunglasses perched on their noses, effortlessly glide down the sparkling sand into the valley. Many use a smallpiece of plastic (a mini-bob) or go down in their bare feet. Monte Kaolino was once featured on the popular German television program ’Galileo,’ showing on Pro7. The highly-publicized World Sandboarding Championships also took place at the Bavarian mountain. As the operator of ’Monte Coaster,’ the SC Monte Kaolino Ski Club must ensure that two of their attractions are secured with video technology according to guidelines provided by the testing facility TÜV Bayern. One is the 800-meter toboggan run with a maximum vertical drop of 55 percent. The other is the 200-meter ’Boat System’ that has to cope with a 150-meter height difference. Skiers and sandboarders use the system like a lift as it carries them to the top of the mountain in a small nine-seater boat. Those not so daring can take its counterpart back down to the bottom of the mountain. MOBOTIX IP cameras have a clear view of the staging area, middle section and the end of each route. Norbert von Breidbach-Bürresheim, Managing Director at VALEO IT Neteye GmbH, planned and implemented video technology at Monte Kaolino. ”There were a few crucial points that showed us that MOBOTIX IP systems are the only ones that can handle difficult challenges.”  Cameras Defy Sand Storms With Winds Of 100 Kilometers An Hour One difficulty was clear from the outset. Fine sand that swirls up very quickly causes problems for standard cameras. The microscopic grains can penetrate cracks in the housing and damage sensitive electronics, which can quickly lead to system failures. Cameras with mechanical zoom or pan functions would quickly reach their limits because any sand in the system would block the control mechanism. Von Breidbach-Bürresheim doesn’t have any of these problems: He has exclusively relied on MOBOTIX IP cameras that feature excellent digital zoom and a completely sealed housing (depending on the model up to protection class IP66) for years. The experts in extreme outdoor conditions recently proved their expertise with installations on Mount Everest and in Antarctica. Even Monte Kaolino occasionally experiences unpleasant weather conditions. Winds can whip up over the mammoth manmade mountain at speeds of up to 100 kilometers an hour and swirl up the fine sand like during a storm in the Sahara. However, this wasn’t a reason for von Breidbach-Bürresheim to rule out the cameras. ”MOBOTIX devices can easily withstand these conditions.” MOBOTIX IP cameras showed what they could do during a comprehensive pre-test in 2008. At that time, operator Wolfgang Schwarz had planned to modernize his old systems. The crystal-clear, detailed images and the reliable housing were so impressive that he did not even attend a competitor’s presentation. Camera Poles: Screwed Into The Sand Mountain With Giant Anchors "The operating costs are low, just like we wanted them to be" Securing the camera poles on the soft, unstable surface was a special challenge for the video specialists.Nevertheless, VALEO IT Neteye GmbH also found a solution to this problem. The poles are screwed deep into the mountain in oversized tubes. The special fittings are similar to the plastic anchors that DIY handymen set in plasterboard for home improvement projects. ”The poles are as steady as a rock. The only thing we ever notice is a slight wobble of the camera image if there are very strong winds around the valley station,” says von Breidbach-Bürresheim. VALEO IT Neteye did not only demonstrate its system expertise in securing, but also during the planning process. It made sense to install as few cameras as possible. After all, according to guidelines provided by the TÜV, an individual viewer must always have a clear view of the toboggan run and the boat system. Too many images would push an individual viewer to the limits of his ability to absorb information. Von Breidbach-Bürresheim achieved the required continuous overview with an astonishingly low number of devices. Just seven cameras are installed on the mountain: four on the toboggan run and three on the lift. Two MOBOTIX M12 cameras, four M22 devices and one new M24 device are currently in use. A Few High-Resolution Cameras – A Lot Of Costs Saved All cameras are fitted with fixed focal length and fisheye lenses. ”This solution is ideal if it’s just a matter of being able to take a quick glance to check if everything is running smoothly. The viewer isn’t overloaded with useless output from extra cameras,” explains von Breidbach-Bürresheim. A quick glance is all that’s necessary for supervisors to see whether teenagers are testing the capacity of a bobsled again. The cameras also feature microphones for audio transmissions. Staff can speak to the guests from the control center at the push of a button. MOBOTIX cameras have an advantage of state-of-the-art IP devices in case there is ever a complaint or an accident. Thanks to the cameras’ high resolution, it is possible to digitally zoom up to eight times at a later point in time and instantly detect the smallest details. Free MOBOTIX MxControlCenter software is installed on standard PCs. It allows you to adjust resolution, frame rate and the recording duration of the video stream, among others, at the click of a mouse. Up And Running In Just Four Days Von Breidbach-Bürresheim, who has been working exclusively with MOBOTIX cameras since 2005, elegantly solved the cabling issue. He installed a supply tube at a depth of 80 centimetres. It contains and protects fiber-optic and two-wire cables. It is possible to upgrade existing cables (telephone cables, bell wires or antenna cables, for instance) for intelligent, cost-effective IP technology using MOBOTIX’s Mx2wire solution. Just one Mx2wire unit is needed at the beginning and end of the cable. The incredible thing is: In addition to data, the energy required to operate the cameras can also be transported using these cables (using PoE). VDSL modems in a small wooden house at the bottom of the mountain transfer the video streams. There is also storage device there, not far from the viewing facility. The images are overwritten every two weeks if nothing important happens. Operator Wolfgang Schwarz believes the complete solution is amazingly simple and effective. ”The operating costs are low, just like we wanted them to be.” He was even more surprised at how fast the system was up and running. In just four days, von Breidbach-Bürresheim had laid all the cables, mounted the poles and cameras and configured the system.

Hikvision Teams With VeViTec-GmbH To Provide CCTV Solution For Germany’s DM Drugstores
Hikvision Teams With VeViTec-GmbH To Provide CCTV Solution For Germany’s DM Drugstores

The CCTV solution includes HD monitor to which IP cameras are directly connected via HDMI outputs As a society, Germany has a well-earned reputation for quality. When German scholars study a subject, they explore every academic option. When German businesses offer a service, they do so with a total commitment and a concern that every aspect be of the highest possible quality. Case in point, when the German giant, DM Drugstores, decided to upgrade their existing CCTV solution for each of their stores across the country, they chose Hikvision. And as its custom, they did so because Hikvision offers a quality that is unrivaled in the security landscape. The Beginning Christian Berkigt, Chief Development Officer at VeViTec-GmbH (the developer of this solution), remarked, “Obviously quality is a huge issue for any German corporation. In this regard, we felt confident that Hikvision would fully meet the demands of both DM Drugstores and VeViTec-GmbH. But, what equally impressed us was Hikvision’s technical support – it really made this solution come together.” But, this solution was not a simple one step process that is often customary in large CCTV solutions of this variety. Instead of the traditional melding of pre-existing analog and newly purchased IP components into a cost-saving hybrid model, VeViTec-GmbH chose an altogether different route. Following the German model of total commitment to quality, VeViTec-GmbH initially utilised two Hikvision PCI compression cards, the DS-4008HCI and the DS-4016HCI. Both cards feature similar technology, such as H.264 (MPEG-4/Part 10) real-time video compression and up-to real-time 4CIF recording, with the main difference being the number of channels each can connect to (8 and 16, respectively). However, these compression cards were meant as only a stop-gap. The IP Future Initially, prior to January 2012, DM Drugstores were using an exclusively analog system. These Hikvision compression cards allowed the older analog cameras to function to the top of their ability. “These are really good cards, providing great quality, and they allowed us to get the best possible video quality on PC monitors in the store locations,” explained Mr. Berkigt. However, January 2012, brought a turning point for DM Drugstores. Instead of moving into the often-used analog/IP hybrid, DM made a total switch to IP. This shift entailed discarding all pre-existing analog technology for this brand-new IP solution. And this is where Hikvision’s service and technology really shined. Securing the outdoors is Hikvision’s DS-2CD752MF-IFB 2.0 megapixel vandal proof network dome camera For DM Drugstores, every centimeter of their store must elicit quality. This goes for mundane aspects such store maintenance, the type of CCTV security the store utilizes, and obviously the product selection DM offers its customers. For DM Drugstores, they wanted to place large HD monitors over the registers for their customers. Not only does this provide an elegant touch of class, it also provides a powerful visible deterrent for any would-be thief. However, DM Drugstores had an unusual request: they wanted a specially designed HDMI output on the adjacent IP camera so as to provide the ability to directly plug this camera into the HD monitor and eliminate cabling back to the server – providing efficiency, a saving of installation costs, and a cleanness not often associated with bulky CCTV installations. For this request, Mr. Berkigt worked with Hikvision to design an indoor custom Hikvision Megapixel Vandal Proof Network Dome Camera to liberally place within all of DM Drugstores’ retail stores throughout Germany. 2,500 of these custom models, the DS-2CD753F-EZ, were built to feature a variety of special features tailor-made for this application and the larger German apprehension of quality. To begin with, the DS-2CD753-EZ’s vandal-proof housing elicits a sense of durability and high standard. As Mr. Berkigt noted, “Just by touching it, you can tell it’s a quality component.” Additionally, the aforementioned custom-made HDMI output allows the DS-2CD753-EZ to be placed directly under, and connected to the HD monitor. Furthermore, a special lens was specifically developed to provide automatic focus, thereby allowing DM technicians a savings of time and effort. “Both the HDMI output and special lens are critical aspects in Germany. We don’t want to waste time, efficiency, and effort. Another representation of this is the appearance, which is a perfect white color, and DM wants everything perfect – something we at VeViTec-GmbH always strive towards. This camera has the technology to provide it all,” Mr. Berkigt explained. "The custom-made HDMI output allows the DS-2CD753-EZ to be placed directly under, and connected to the HD monitor" Securing the outdoors is the DS-2CD752MF-IFB 2.0 Megapixel Vandal Proof Network Dome Camera featuring infrared LED. Unlike the previous Hikvision IP camera, this unit is a standard catalogue model. One unit of this camera is placed outdoors near the back exit used by employees before leaving the store after their shift. Similar to the already-noted HD monitor used by customers, an HD monitor is placed indoors near the backdoor for employees to initially check before exiting into the already dark evening, hence the importance of the DS-2CD752MF-IFB’s infrared ability. In essence, this camera is a security precaution for DM employees. Concurrently, a high-resolution video preview of 1600×1200 pixels provides the details to ensure that any potential threat is identified well before an employee might encounter it outdoors. Additionally, owing to the German sense of uncompromising quality, a custom bracket was designed allowing the DS-2CD752MF-IFB weather protection against the harsh winter conditions the German landscape is famous for. From custom to catalogue, and from color to quality, Hikvision teamed with VeViTec-GmbH to provide a total, and quality-driven, CCTV solution for Germany’s DM Drugstores. Where each customer-viewed HD monitor now has 2 to 3 IP cameras directly connected via HDMI outputs, each store has a Hikvision infrared IP camera guarding its employees. Unique solutions for unique security challenges, all highlighting DM Drugstores total commitment to quality.
