Geutebruck GeViScopes safeguard Gasunie’s gas grid across the Netherlands and Northern Germany
Geutebruck GeViScopes safeguard Gasunie’s gas grid across the Netherlands and Northern Germany

With over 15,000 kilometres of pipeline in the Netherlands and northern Germany, dozens of sites and approximately 1,300 gas receiving stations, Gasunie operates one of the largest high pressure, gas pipeline grids in Europe.  Its network forms the core of the so-called northwest European 'gas roundabout' and its security relies on Geutebruck technology. Gasunie's sites vary greatly in function and size.  Some are very small, remote and rarely visited.  Others occupy several hectares and are occupied by dozens of Gasunie employees and visiting contractors.  The security infrastructure depends on the site and ranges from simple fencing to sophisticated fence systems with perimeter detection systems and CCTV.  "The fundamental requirement at every location is that unauthorised intruders are always identified as fast as possible at the perimeter," explains Reiner Woldring, Gasunie's corporate security advisor.  "Where necessary there are two high fences with alarm systems on the outer fence," adds Herman von Hierden, a member of Gasunie's electrotechnics, instrumentation and process control department.  "That way unauthorised intrusion can be detected even earlier." The CCTV systems operating on 25 sites allow security processes which are aimed at limiting access to authorized staff, such as verifying and tracking intruder alarm reports, to all be coordinated from the 24-hour Groningen control centre. "We need camera pictures for verifying the alarm reports which may need to be followed up by the police or another special guarding service," reports Reiner Woldring.  "For this we need good quality cameras, reliable transmission and storage of camera pictures as well as user-friendly functions for calling up the pictures in the alarm centre." To keep its systems up to date Gasunie operates a rolling programme of infrastructure expansion and modernisation which applies to the security equipment too.  All its cameras are currently managed through a modern Geutebruck GeViScope platform which is fully integrated into the company's own management system.  Local system integrators Alphatron and Strukton Systems have been responsible for upgrading the cameras and remain responsible for the maintenance of the alarm centre systems.  Whenever there is an alarm, control centre staff can immediately replay the recorded footage IP-based systems are now standard across all sites.  "Nowadays we work with a lot fewer cameras per site" explains Herman von Hierden, "and most of them can be remote controlled from the centre." Control centre staff can call up camera images in real time and immediately replay the recorded footage whenever there is an alarm. Automatically controlled lighting has made nocturnal camera surveillance possible even on remote sites. - The challenge on remote sites has always been data connectivity.  "The limited bandwiths available between head office and some of Gasunie's remoter gas pumping locations generate perfect environments for Geutebruck equipment to demonstrate its efficient bandwidth management," grins Koen Pelle, Geutebruck country manager for the Netherlands. Protecting such a nationally and internationally critical infrastructure network involves preparing for everything - including a catastrophic failure which knocks out the Groningen control centre.  For this eventuality Gasunie has set up an equivalent security centre at an undisclosed location elsewhere in the Netherlands.  "Whenever necessary this second centre can be used to take over all duties," assures Reiner Woldring.

Geutebruck video security system enables 24/7 suicide prevention at an Australian beauty spot
Geutebruck video security system enables 24/7 suicide prevention at an Australian beauty spot

Gap Park in Sydney, Australia extends for a couple of kilometres along sheer rugged cliffs facing the Pacific Ocean.  It is an area with stunning scenery, but sadly also a history of suicides, accidents and unexplained deaths. To reduce these tragedies and improve the park’s image, Woollahra Municipal Council implemented a master plan involving both deterrence and response measures which now includes a Geutebruck GeViScope-based video security system designed by Security Consultants International and installed by Kings Security Systems. Initial consultations with local people, mental health and crisis support agencies revealed that troubled individuals often spend several hours on the cliff tops before finally deciding to commit suicide, and that active intervention during this period might save life. Hence the council’s plan for reducing self-harm incidents, improving the area’s reputation and encouraging more visitors, included a video surveillance system to aid rapid police intervention by enabling critical incidents to be identified day or night.  Initially the project included restyling the park entries, erecting new inward curving fences along the cliff edge to deter climbing, as well as new seating and low level LED lighting to improve the ambience especially at night. New signs were installed as were two purpose-built, vandal-resistant telephone help points with autodialing for the charity Lifeline and the emergency services, together with automatic audio visual feeds and location ID. Four Bosch MIC 412 thermal PTZ cameras provided vision at night and in bad weather, at considerable distance and amongst vegetation.  With subsequent federal funding in 2011 came a GeViScopeHS/R with an expansion unit; new fixed view cameras to monitor the telephone help points; and five Moog ‘thermal & optical’ cameras for providing thermal and optical views at the same time.  Most cameras are concentrated near the entrances and along the cliff-top walk so that monitoring centre operators can help police with missing persons searches by identifying individuals as they enter or leave the park, and locating them if they remain in the park. The remote operator only views the live video and assesses the situation when requested to do so by the police – i.e. when a member of the public has reported a possible incident, when there has been an emergency call from a help point, or following an alert from Lifeline. The operator can also review recorded footage for post-incident investigation but only with specific permission from the Council.  Justine Henderson, communications manager and spokesperson for Woollahra Council reports, “We know the footage has been useful to police in responding to potential on site emergencies as we’ve seen an increase in use of the monitoring provided by the camera system. At the start of the project the footage was being used for retrospective investigations and now it is being used more for direct interventions – which is a good result.” Geutebruck video analytics (VMD) on thermal camera streams can accurately identify dangerious incidents and provide a reliable basis for alerting the emergency services  Analytics with thermal camerasIn autumn 2011 an extended trial using a selection of existing cameras was successful in establishing that Geutebruck video analytics (VMD) on thermal camera streams could accurately identify dangerous incidents and provide a reliable basis for alerting the emergency services.  The GeViScope’s VMD software was set up with two lines of alarm zones, one along the fence and one parallel on the seaward side. Time thresholds were used to pick up someone climbing over the fence, and an alarm was set to trigger immediately if a target moved from the first line of zones into the second line at the cliff edge.The tests correctly identified incidents where individuals, or groups, breached the safety fence and ventured out to the cliff edge. Some people were clearly just making sight-seeing or thrill-seeking explorations but others seemed to have more troubled motivations. False alarms were minimal and proved very easy for operators to recognise and disregard. The tests correctly identified incidentswhere individuals, or groups,breachd the safety fence and ventured out to the cliff edge  In the light of this success Woollahra Council is seeking funding to add a small number of fixed view cameras to the video system to establish a permanent analytic detection ‘fence line’. This VMD option is substantially cheaper than ground-based radar and offers the advantage of combining video display, detection and verification all in one.  With some dedicated fixed view cameras taking care of these core functions, the existing PTZ cameras would then be available to provide the operator with a wider view, more accurate details etc., without risk of disturbing the VMD function. “Geutebrück Pacific’s entire team are particularity proud of this project,” says managing director, Anthony Brooks. “It’s very exciting to be applying this advanced technology outside the traditional security environment where it has the potential to deliver very positive outcomes for many individuals and their families. We can’t think of a more worthwhile and satisfying project.”

Geutebruck’s virtual servers provide unprecedented performance and reliability in a Swiss Casino
Geutebruck’s virtual servers provide unprecedented performance and reliability in a Swiss Casino

When the Grand Casino in Baden in Switzerland upgraded its video security system in 2009 it installed a Geutebruck high availability IP solution with virtual GeViScope platforms and incorporating thirty-five 1.3 Megapixel cameras. The 250-camera system provides a complete video history from all cameras, including the megapixel ones, at full available resolution for 28 days on a 320 Terabyte instant access database.  Two technologies were key to achieving unprecedented performance and reliability.  One is Geutebruck’s own CCTV-optimised video compression process MPEG4CCTV.  This uses standard MPEG-4 compression tools in unusual ways to deliver professional performance and image handling specifically for security users.  MPEG4CCTV systems are not only remarkably fast, delivering top quality video images without latency; but also lean and efficient with low network and storage requirements. The other notable technology is virtualisation. Geutebruck uses virtualisation, in the shape of Microsoft’s Hyper-V tool, to generate multiple virtual GeViScope servers in fail-over cluster formation on a single piece of hardware, thus providing high redundancy but without additional hardware. Consequently, the server room at the Grand Casino Baden is impressive for what is not there! — Less hardware means less power and less emergency capacity on standby; fewer devices mean less waste heat, less air conditioning and lower energy consumption. Together, space, energy and cost savings mean virtualisation significantly reduces the Casino’s total cost of ownership. System design The system’s cameras include a dozen legacy analogue speed domes and a hundred analogue box cameras all now linked to an existing Kat5 Ethernet with CAM2IP video encoders; 35 new 1.3 megapixel cameras and a hundred new VIPCAMs - high resolution day/night IP-cameras. Two Intel servers each incorporating five high performance computers handle all data streams and run 21 virtual GeViScope video system platforms operated in cluster formation.  These record to RAID Level 6 databases mounted on 21 Promise SAS storage systems with sixteen 1TB capacity server disks each.  If - despite all care and cutting-edge technology – something does fail, then the full functionality of the system is immediately automatically re-established without down-time or data loss. The systems' cameras include a dozen legacy analogue speed domes and a hundred analogue box cameras The new megapixel cameras provide improved picture quality along with support for close-ups.  On their 30-inch monitors supervisors can view all 250 cameras and can pull up live and recorded footage of identical quality in milliseconds.  Despite its technical complexity, supervisors find the system simplicity itself to operate as the user-friendly GSCView display and operating software is extensively customised for each application, optimizing operator comfort and convenience.  “Virtualisation offers end-users significant advantages,” reports Carmen Lahr, Geutebruck corporate communications director. “Not only does it enable redundancy and high availability to be achieved without hardware duplication; but using hardware resources more efficiently like this reduces the installation’s need for space, power and cooling, and that cuts the system’s overall energy consumption by 30-40%.”
