Geutebruck's GeViScope Protects New Japanese Embassy In Cairo
Geutebruck's GeViScope Protects New Japanese Embassy In Cairo

When the Japanese Embassy in Cairo moved to its new building on the banks of the Nile, it chose a Geutebruck CCTV monitoring system despite fierce international competition - especially from Japanese manufacturers.  The Embassy's hundred-camera, five-workstation system is based on the GeViScope digital CCTV platform.  With a dedicated digital signal processor for each video channel, the GeViScope has both the capacity to process large amounts of data, and the flexibility to process each signal differently, precisely as required.  Dual channel streaming enables it to stream and record the same scene in different qualities simultaneously, here for example, 25fps 4CIF video for smooth real-time viewing and 10 fps 4CIF footage for later detailed analysis.  How did it outperform its competitors?  According to Harun Oezerdem, Geutebruck's area manager for Eurasia: "The GeViScope system was selected primarily because it records faster and at higher resolutions, and because it supports multiple CCTV platforms, but it has other things going for it too.  At the new embassy sensitive areas are protected by video motion detection and the GeViScope can deliver alarm pictures to GSM mobiles if required.  Also, because it's a DSP-based system, adding new functionality is just a matter of loading new software, so the system is easy to expand and update, and you can keep it state-of-the-art indefinitely." The GeViScope delivers faster recording at higher resolutions not only because of its multiple processors, but also because of its unique compression process called MPEG4CCTV.  This method of encoding was specially developed by Geutebruck for generating large numbers of different video-audio channels simultaneously, without overstretch at high loads or speeds.  It is an MPEG4 process but it incorporates variable quality and variable compression.  It lets the user define the image quality (including the GOP sizes) for each individual recording and each individual live streaming channel from each camera - whether analog or IP (or megapixel).  The process then maintains this desired picture quality, while automatically changing the frequency of reference frames in real-time, in accordance with the overall movement in the picture, the motion in selected areas, other event triggers and any scheduled routines. By focusing on delivering what is important to the CCTV user, and only generating data relevant to his needs, MPEG4CCTV minimizes data volume, bandwidth and storage costs, and has such a low latency (120ms) that it can be used to control fast dome and PTZ cameras.  Users enjoy exceptional display characteristics: smooth, multi-camera synchronised playback, forwards and backwards at any speed (from 1 picture/10s to 25fps and even image by image), and, with a single keystroke they can jump back seconds or minutes to view sets of synchronised recordings.  Easily to copy for back-up and evidential purposes, MPEG4CCTV footage can be protected with individual password encryption and cannot be manipulated in multimedia editors. 

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

Camera surveillance on remote sites is possible even at night thanks to automatically controlled lighting 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 unauthorized 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 unauthorized 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 center. "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 center." 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 center systems.  Whenever there is an alarm, control center 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 center." Control center 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 center.  For this eventuality Gasunie has set up an equivalent security center at an undisclosed location elsewhere in the Netherlands.  "Whenever necessary this second center 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 center 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 recognizeand 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.”
