Security ready for take off: MOBOTIX helps protect 11 million passengers at major Italian airport
Security ready for take off: MOBOTIX helps protect 11 million passengers at major Italian airport

Security at airports has become indispensable, and entails continuously increasing requirements. The only way to keep satisfy the most demanding standards day after day, is to constantly further develop the technology in use. Video surveillance is a crucial contribution to airport security; this technology has a great deal of potential, as long as the current configuration is not taken as the final goal in terms of development. Il Caravaggio airport expansion phase “Since the technological developments and the need to increase the level of security were clearly evident, we could no longer put off considering a flexible video surveillance system, one that would be ready to meet the security and analysis requirements and guarantee a high level of performance,” says Ettore Pizzaballa, Manager of Information Systems at SACBO S.p.A. The important expansion phase at the Il Caravaggio International Airport terminal, which involved building a long gallery of shops and expanding the passenger boarding area, made the situation even more complex and challenging. This added another piece to the puzzle, alongside the usual airport security scenarios. The video analysis software allows us to better understand how the flow of passengers moves inside the terminal" Improving surveillance image quality Il Caravaggio International Airport is the third-largest airport in Italy in terms of traffic, with a volume of over 11 million passengers. Security is crucial when it comes to an airport infrastructure of this size, and a great deal of attention is required to maintain the necessary level of surveillance. Introducing MOBOTIX technology (offered by the systems integrator Tecnosystem) enhanced the quality and resolution of the surveillance images. In turn, this further improved the activities carried out together with the constantly present police forces operating at the Il Caravaggio International Airport terminal, thereby providing suitable support for investigations. “Inside the airport, not all the halls are homogeneous in terms of height and lighting; thanks to MOBOTIX, we were able to achieve excellent image quality under all conditions.” Analysing aircraft and vehicle movements Video surveillance has also turned out to be a valuable additional tool for improving operating procedures related to safety: “We can analyse aircraft and vehicle movements in the manoeuvring areas to help train operating personnel. Even the luggage is constantly under surveillance: If a piece of luggage stops or is stuck where employees can’t see it, the system immediately sends a notification to employees”. Several different models were used in keeping with needs, including the c25, i25, M24/25, 24/25, S15, S15 SurroundMount, M15/16 and T25 The parties involved aim to complete the project within two years. That may appear to be a long period of time, but it is actually rather short considering the complexity and scale of the task at hand. Over 300 MOBOTIX video cameras have been installed, both indoors and outdoors. Several different models were used in keeping with respective needs, including the c25, i25, M24/25, 24/25, S15, S15 SurroundMount, M15/16 and T25. Each one of these cameras is active 24/7. The new VoIP infrastructure and NAS recording allow the different control rooms to share the images. Perfect synergy between hardware and software When it comes to ensuring state-of-the-art security, though, even the most advanced hardware technology does not suffice to cover all of the related tasks. A less visible component plays an important role in ensuring the efficiency of MOBOTIX solutions. “In addition to the image quality, we were also impressed by the option to receive thoroughly customisable software based on our specific requirements – not to mention the video analysis functionality.” At this point, it is actually easy to spontaneously develop ideas for the future, expanding the field of application of a system that boasts continuously developing potential, and utilising the video surveillance infrastructure and its video analysis applications in order to obtain immediate and concrete results. The benefits are numerous: “The video analysis software allows us to immediately detect abandoned objects, locate the optimum route for vehicles in the manoeuvring area and better understand how the flow of passengers moves inside the terminal (which we need to plan optimal routes), studying which type of traveller goes directly to the gate and which one stops instead to make purchases at the shops. The software also allows us to constantly monitor the lines at security checks and check-in and boarding areas in real time,” summarises Pizzaballa.

MOBOTIX cameras enhances human and animal safety at The Opel Zoo, Germany
MOBOTIX cameras enhances human and animal safety at The Opel Zoo, Germany

MOBOTIX' highly specialised video sensors were perfect for application at The Opel Zoo in Germany The Opel Zoo in Kronberg/Germany, originally known as the “Georg von Opel Outdoor Enclosure for Animal Studies,” provides expansive compounds and enclosures for around 1,500 animals spread across 27 hectares. There are more than 200 species being kept at the zoo, and many of them are endangered. Located on the southern slopes of the Taunus mountain range and offering fantastic views of the Kronberg old town and the Rhine-Main region behind it, the Opel Zoo is one of the most popular leisure and culture destinations in the state of Hesse, attracting around 650,000 visitors per year. One of the zoo’s main draws is its generous new enclosure for African elephants – the only one of its kind in Hesse. The new elephant enclosure The new elephant enclosure, which was completed in the fall of 2013, is the zoo’s most ambitious construction project to date. The new elephant house provides its residents with large individual pens. In addition, an indoor run of more than 800 square meters gives the smaller elephants plenty of space to get out of the way of the more dominant ones. Combined with the three outside sections that have a total area of 8,000 square meters, this gives the four residing elephants ample opportunity to both converge and avoid each other when so desired. Better vantage for critical areas “During the planning of the enclosure, we focused on both the welfare of the elephants and on the safety of the premises,” explains Dr. Thomas Kauffels, the director of Opel Zoo. “It’s very important to know at any given time where each animal is located, which gates are open and which need to be closed.” The initial plan made during construction was to install a set of pan/tilt cameras in the elephant enclosure. When it came to the implementation of these, however, the camera concept turned out to have several flaws, and Opel Zoo contracted Encom Consulting from Saarwellingen to remedy the situation. "During the planning of the enclosure, we focused on both the welfare of the elephants and on the safety of the premises" Encom Consulting had already worked for the zoo for several years, among others for the installation of multipath transmission systems. A specialist for security solutions and risk management, the company had also installed the zoo’s first high-resolution webcams, which among others monitored and documented the construction of the elephant enclosure. The webcam feeds could also be viewed online on the zoo’s website. When assessing the original camera concept, Encom realised that the planned pan/tilt cameras would not be able to fulfil many of the requirements. Cost was another important factor. The pan/tilt cameras would have required a large number of expensive optical fibre cables. Optical fibre was particularly needed in the high voltage area to avoid interference. The original concept also entailed a much larger number of cameras in order to cover all the required areas; the new concept required significantly fewer units. For cables in the proximity of high voltage systems, Encom developed a pulse interference elimination process that made it possible to do without optical fibre. Due to the differences in cost and also in quality of security provision, the management at Opel Zoo decided to abandon their original camera concept and instead contracted Encom to implement the network and install the MOBOTIX cameras they had recommended. With these, the hardware costs alone were decreased by almost 30 percent – not counting the significant follow-up cost reductions, among others resulting from lower power consumption and the MOBOTIX solution’s much lower maintenance requirements. MOBOTIX’s FlexMount cameras For example, the semi-circular elephant corridor only needed three of MOBOTIX’s FlexMount cameras. The FlexMount is a very versatile model featuring two hemispheric lens units, each of which is connected to the camera processor via a one to two-meter cable. With its twin sensor modules, the camera can look ‘around the corner’; this enables it to monitor a fully hemispheric area. The camera processor outputs two undistorted, high-resolution 180-degree panoramic video feeds. The current resolution is 3.1 megapixels, which is set to be increased to 6 megapixels in the future. With the installed cameras, the entire elephant corridor can be monitored seamlessly. All it takes is three cameras to simultaneously show all twelve viewing angles on-screen. Each of the cameras features one day and one night sensor covering the same physical area. The cameras automatically select the best camera module to suit the light level, and similarly, the software automatically uses the most suitable exposure settings. The semi-circular elephant corridor only needed three of MOBOTIX’s FlexMount cameras All of the cameras feature highly specialised video sensors for both day and night mode. In the rare event that panning and zooming is needed, this is performed electronically within the video feed. Thanks to the high megapixel resolution, this is usually possible without requiring any degrading interpolation. The zookeepers are thus provided with detail views and other image sections without any mechanical movement of the lens, i.e., the sensor, and therefore without any wear and tear. Because there are no movements, there is no need for a motor, which means there is no risk of mechanical failure and no need for costly maintenance. Before entering the elephant corridor, the keepers can always tell if there are any elephants inside the connecting corridor. This information is provided via a laterally-mounted, fully dustproof MxDisplay. The same applies for the elephant house’s indoor run. Here, a number of FlexMount and AllroundDual cameras are installed as well. These provide the zoo with a full view of the indoor run right up to the visitor platform, all on the same screen. Mobotix AllroundDual cameras As well as the high-up AllroundDual cameras, the outside area also features a number of FlexMount cameras. Thanks to their very small image sensors and up to two meters of distance to connect to the separately-housed camera processor, these could be positioned very discreetly. This is of crucial importance in an elephant enclosure. With other systems, the cameras would have to be installed well outside of the elephant trunks’ reach, which usually means a height of at least six meters. “Elephants are very inquisitive, and they like to inspect things thoroughly. An elephant’s trunk can weigh up to 200 kilograms, which means the cameras need to be installed in a way that they won’t be damaged by a strong slap,” says Jasper Jasperson. “With this system, the video image sensors were integrated very inconspicuously into our molded rock surfaces. We can now record footage at a comparatively low elevation of just three meters above the ground. For the first time, we can view the elephants ‘eye to eye.’ At the same time, being closer to the ground gives us a more faithful perspective on objects in the distance.” In designing the cable layout, Encom also paid attention to the zoo’s special requirements, with top priority given to failsafe operation Priority to failsafe operation In designing the cable layout, Encom also paid attention to the zoo’s special requirements, with top priority given to failsafe operation. Because of this, the number of active devices in the field was reduced to the barest minimum. Optical fibre is only used where absolutely necessary, i.e., where extreme distances need to be covered; this isn’t only for cost reasons but also to keep down maintenance. Ultimately, only two optical fibre cables were needed, both of which are used outside to connect to the watering spots 400 and 500 meters away. All of the other camera locations are connected using direct wide-range copper cables. These cables also supply the MOBOTIX cameras with power (three to five watts). According to the specifications of the originally proposed system, each camera was going to consume 55 watts – that’s more than ten times the amount of power. Even when there is a power failure, the MOBOTIX cameras continue to be supplied from a UPS, ensuring the security feed is never interrupted. A single 360-degree camera provides a fixed view of the entire outside area of the elephant compound, offering a panorama over 5,500 square meters. This main view is supplemented by further 90-degree cameras for a separate lower section. This way, the keepers can always see where each animal is currently located. As well as for safety and security, Opel Zoo also uses its cameras to research animal behaviour. In order to minimise intrusive external factors while still providing around-the-clock visual data of the animals, Encom Consulting again recommended the use of hemispheric MOBOTIX cameras. These make it possible to see exactly how the elephants traverse the compound, which routes they take and when they interact. With its special lens, the FlexMount camera provides a full view of almost the entire area, recording uninterrupted footage over many months. Thanks to the hemispheric system, this is possible using just a single camera – with the originally planned pan/tilt cameras, six to eight individual cameras plus ongoing manual repositioning would have been necessary. For each camera not installed, Opel Zoo is saving four-digit amounts in acquisition, cable, and maintenance costs; this adds up to a substantial difference. Having fewer cameras also means there are less feeds to take up screen space, and resultantly, the remaining camera feeds can be displayed at a much bigger size. In a similar vein, the FlexMount also offers another important advantage: With a multi-camera system, the animals constantly move from one viewing area to the next, whereas with a single hemispheric panorama camera, they remain within the one 360-degree view. They never disappear from the video feed, nor do they double up in overlapping viewing areas. And when the sun is low, all the animals remain fully visible despite the strong backlight. This is only possible because the MOBOTIX camera – in contrast to other designs – does not use an iris. The widescreen panoramic image provides roughly twice the resolution of a standard video image The patented MOBOTIX high-tech image processing algorithms inside the camera calculate and correct the complex pixel array, eliminating the need for an iris and its inherent susceptibility to backlight. The widescreen panoramic image has the same number of lines as a standard video image but provides roughly twice the resolution. The camera-integrated motion analysis software makes it possible to trigger recording in response to predefined events – such as an elephant entering or exiting an area. This greatly speeds up research later on, saving the zoo both employee time and data storage space. “The free-of-charge MOBOTIX software is so easy to use that our team could start analysing the images almost immediately, producing valuable findings for our daily interactions with the animals, as well as supplying great image material for documenting the animals,” says Uwe Böhme, administration manager at Opel Zoo. Researching the behaviour of the Rothschild Giraffes Another set of cameras is installed in the zoo’s enclosure of Rothschild giraffes. In this instance, the focus is less on security and safety than on research, such as the projects being conducted by the Opel Zoo-sponsored Chair in Zoology at Frankfurt’s Goethe University. Endowed Professor Paul Dierkes and his team are making excellent use of modern image-gathering methods in their research, which is focused on the animals’ wellbeing and relies on unobtrusive research equipment. In this enclosure, six FlexMount S15 and AllroundDual M15 cameras are in use. Both of these models have a resolution of five megapixels. Thanks to the sensors used in these cameras, the zoo’s research team can benefit from outstanding light sensitivity. Additionally, the sensor technology offers a frame rate of up to 30 frames per second, as well as extreme zooming. Not only does this produce sharper images, it also allows for the cameras to be positioned further away from the areas to be monitored. Accordingly, it was possible to install the cameras well out of the giraffes’ sight. The M15 is a day-and-night camera; depending on the configuration, both day and night recordings can be made simultaneously, which is particularly valuable in poor lighting conditions or in complete darkness. Encom is also testing specially-designed animal camouflage housings with optical shutters – despite fully blending in, they still output a high-quality colour image. This is making it possible to capture footage that was previously either impossible to get or would have required a lot more effort. Thanks to the sensors used in these cameras, the zoo’s research team can benefit from outstanding light sensitivity Mobotix cameras with thermal sensors For testing purposes, the newly-developed MOBOTIX cameras with thermal sensors are being deployed in both the elephant and giraffe enclosures. With the thermal sensors, the animals’ body heat can be traced visually. The cameras can therefore detect movements from distances of up to 400 meters very precisely, even under challenging lighting and weather conditions. The future of thermographic cameras in animal research looks very promising. For example, they can be used to display images of animals living in caves or nesting without intruding on them at all. There are also interesting possibilities in the area of preventive veterinarian diagnoses. Cost effective with enhanced safety As well as the animal enclosures, the zoo shop and ticketing area are also being secured using MOBOTIX cameras. “We’re very happy with our camera systems, particularly with how Encom managed to adapt the complex camera programming to our needs. The same applies to the excellent MOBOTIX cameras, which are wonderfully sturdy,” says Uwe Böhme. As well as the increased safety and security provided by the new camera concept, the zoo also benefits from having significantly fewer power cables than originally planned for, and power consumption has been reduced to a mere tenth. Similarly, the risk of cameras failing has also been reduced by a factor of ten. “Compared to our original pan/tilt camera concept, we’ve now got a better set of features and still managed to save around 30 percent on hardware and software,” says Böhme. “That doesn’t even include follow-up costs, such as the maintenance that would have been needed over the years; with the MOBOTIX cameras, this isn’t needed at all. We’ve already started planning for further camera systems around the zoo.” One of the next projects is to test further motion analyses for the colour-based display of animal routes through their compounds.

Hikvision IP CCTV system secures perimeter and enables remote monitoring of workshop for GRW, South Africa
Hikvision IP CCTV system secures perimeter and enables remote monitoring of workshop for GRW, South Africa

GRW is one of South Africa’s leading providers of sophisticated road transport trailers; designing, manufacturing and servicing a wide range of bespoke vehicles, each configured to provide a solution to the unique transportation needs of an individual client. GRW has now invested in a state-of-the-art IP CCTV system to protect its premises against unauthorised access and monitor the large, modern production facilities, and is already reaping the benefits from the integration of analytics with the IP cameras. GRW transport operations Founded in South Africa in 1996, GRW’s operations have always revolved around the transport of commercial goods. Whether it’s carrying petroleum, chemicals, temperature-controlled perishables, FMCG, pallets or bulk general cargo, the trailers manufactured by GRW are specifically designed to meet the individual transportation requirements of customers throughout Southern Africa, the Middle East, Australia and the UK. All the company’s products emerge from its large, ultra-modern manufacturing complex in Worcester, in South Africa’s Western Cape. As well as housing the extensive production facilities and spare parts department, the facility is also home to GRW Services and GRW Financial Services, which are responsible for worldwide customer care and after-sales contract servicing and the supply of rental units. Surveillance of the perimeter of this large facility and protecting the plant from unauthorised access was a key security concern for the company. However, manned patrols of the perimeter proved ineffective and Sensor Security was tasked with designing a solution that would automate the process of securing the boundary and eliminate the possibility of human error. At the same time, GRW recognised that an intelligent camera infrastructure might enable remote monitoring of the production process and Sensor Security was asked to investigate.Surveillance of the perimeter of this large facility and protecting the plant from unauthorised access was a key security concern for the company Integration of analytics with IP cameras “From the outset we knew that the proposed CCTV system should successfully serve a dual purpose, helping supervisors and managers monitor the workshop operations during opening hours and securing the perimeter 24 hours a day,” says Edmund Casaleggio, Sensor Security’s Sales Executive. “There was also a need to make the combined system as simple and easy to operate as possible, ensuring that operations staff had unrestricted access to the workshop video feeds while not being distracted by the security cameras and vice versa for the security officers, who are best served by complete concentration on securing the premises.” Following extensive consultations with GRW staff, the final design of the dual-purpose system involved a total of 18 Hikvision cameras, eleven on the perimeter and seven in the workshop area, all feeding in to a 32-channel Hikvision NVR at GRW, and to Security Sensor’s control room. “GRW was actively involved in the whole consultation and design process, right from day one, with suggestions on key sites needing monitoring and protecting and information and advice on the flow of work and personnel around the workshop area” continues Edmund Casaleggio. “This was hugely beneficial and one of the main contributory factors in the successful installation. In my experience it is always more challenging, risky even, to install any security-related system without sufficient input and collaboration from the end-user client.” A smart perimeter Perimeter patrolling with guards having proved ineffective, GRW was also keen that the introduction of cameras did not mean that an individual would have to be assigned to constantly manage the CCTV system around-the-clock. Therefore, the Hikvision DS-2CD4012F-A Smart 1.3MP low-light box camera was selected to monitor the perimeter of the plant, with active use of the cameras Smart Analytics intrusion flags ensuring that GRW’s security officers and Sensor Security’s control room are pro-actively notified of any unauthorised movement around the premises.  According to Edmund Casaleggio, “The integration of analytics with the Smart IP CCTV cameras is a significant added advantage, flagging alarms only when intrusion occurs within the specified range. We do not have to use alarm inputs and outputs to connect passives and actives on the DVR/NVR, which saves significantly on maintenance of the system. It also reduced installation time significantly. What’s more, the accuracy of these Smart cameras with analytics is far better than beams, as long as the cameras are correctly calibrated when installed. In this regard, the Auto Back Focus on these Smart cameras greatly assists the installation technicians to achieve the best possible viewing quality.”  As well as the Smart Intrusion Detection, the Hikvision DS-2CD4012F-A also features Smart Codec, Smart Focus, Smart VQD, Smart Face Detection and Smart Audio Detection. They also benefit from 3D DNR and Digital WDR, and the Day & Night IR cut filter allows successful video operation down to 0.001 Lux. Remote monitoring of perimeter and workshop Seven Hikvision DS-2CD2132-I 3MP Mini Dome Cameras keep watch over all operations in the workshop area, assisting the supervisors and managers to remotely monitor processes on the floor. This process is made much easier and more efficient for these staff due to the integration of the Hikvision DS-9632NI-ST 32-channel NVR with a PC, ensuring that operational staff are only presented with images relevant to the production area.GRW is already reaping the benefits from the integration of analytics with the IP cameras and is set to continue for many years" “The full HD, 1080p real-time video is a huge asset for the supervisory staff and the camera itself, protected within its IP66 vandal-proof housing, has withstood the rigours of a harsh industrial environment really well,” continues Edmund Casaleggio. “True day/night operation thanks to its 30m IR range and Digital WDR and 3D DNR also contribute to the high-quality video at all times.” A real success “This newly-installed state-of-the-art IP CCTV system automates the process of protecting GRW’s premises against unauthorised access and monitoring the production facilities while eliminating the possibility of human error,” says Edmund Casaleggio. “GRW is already reaping the benefits from the integration of analytics with the IP cameras and is set to continue for many years. “At the same time, they are benefitting from the user-friendly nature of Hikvision’s technology. This deceptively “simple” platform helps GRW staff to operate the software easily with minimal training while Smart features, such as ABF, aids our technicians to achieve the best possible video quality. “However, the quality of Hikvision’s hardware and software does not come with an unaffordable price tag. In fact, since Hikvision’s iVMS-4200 software allows for the integration of analogue and IP cameras free-of-charge, this serves to increase the affordability of their products. What’s more, the free Hikvision software allows the feeds from analogue and IP cameras to be integrated on one screen. “In conclusion, Hikvision’s huge range of cameras, NVRs, DVRs and software allows us to propose unitary solutions to their security needs and to more successfully back-up and service the installation over many years. Quite simply, it is easier to provide post-sales service and support with a single, reliable brand.”
