Ski jump
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.

How Have Security Solutions Failed Our Schools?
How Have Security Solutions Failed Our Schools?

School shootings are a high-profile reminder of the need for the highest levels of security at our schools and education facilities. Increasingly, a remedy to boost the security at schools is to use more technology. However, no technology is a panacea, and ongoing violence and other threats at our schools suggest some level of failure. We asked this week’s Expert Panel Roundtable: How have security solutions failed our schools and what is the solution?

Why Visualization Platforms Are Vital For An Effective Security Operation Center (SOC)
Why Visualization Platforms Are Vital For An Effective Security Operation Center (SOC)

Display solutions play a key role in SOCs in providing the screens needed for individuals and teams to visualize and share the multiple data sources needed in an SOC today. Security Operation Center (SOC) Every SOC has multiple sources and inputs, both physical and virtual, all of which provide numerous data points to operators, in order to provide the highest levels of physical and cyber security, including surveillance camera feeds, access control and alarm systems for physical security, as well as dashboards and web apps for cyber security applications. Today’s advancements in technology and computing power not only have increasingly made security systems much more scalable, by adding hundreds, if not thousands, of more data points to an SOC, but the rate at which the data comes in has significantly increased as well. Accurate monitoring and surveillance This has made monitoring and surveillance much more accurate and effective, but also more challenging for operators, as they can’t realistically monitor the hundreds, even thousands of cameras, dashboards, calls, etc. in a reactive manner. Lacking situational awareness is often one of the primary factors in poor decision making In order for operators in SOC’s to be able to mitigate incidents in a less reactive way and take meaningful action, streamlined actionable data is needed. This is what will ensure operators in SOC truly have situational awareness. Situational awareness is a key foundation of effective decision making. In its simplest form, ‘It is knowing what is going on’. Lacking situational awareness is often one of the primary factors in poor decision making and in accidents attributed to human error. Achieving ‘true’ situational awareness Situational awareness isn’t just what has already happened, but what is likely to happen next and to achieve ‘true’ situational awareness, a combination of actionable data and the ability to deliver that information or data to the right people, at the right time. This is where visualization platforms (known as visual networking platforms) that provide both the situational real estate, as well as support for computer vision and AI, can help SOCs achieve true situational awareness Role of computer vision and AI technologies Proactive situational awareness is when the data coming into the SOC is analyzed in real time and then, brought forward to operators who are decision makers and key stakeholders in near real time for actionable visualization. Computer vision is a field of Artificial Intelligence that trains computers to interpret and understand digital images and videos. It is a way to automate tasks that the human visual system can also carry out, the automatic extraction, analysis and understanding of useful information from a single image or a sequence of images. There are numerous potential value adds that computer vision can provide to operation centers of different kinds. Here are some examples: Face Recognition: Face detection algorithms can be applied to filter and identify an individual. Biometric Systems: AI can be applied to biometric descriptions such as fingerprint, iris, and face matching. Surveillance: Computer vision supports IoT cameras used to monitor activities and movements of just about any kind that might be related to security and safety, whether that's on the job safety or physical security. Smart Cities: AI and computer vision can be used to improve mobility through quantitative, objective and automated management of resource use (car parks, roads, public squares, etc.) based on the analysis of CCTV data. Event Recognition: Improve the visualization and the decision-making process of human operators or existing video surveillance solutions, by integrating real-time video data analysis algorithms to understand the content of the filmed scene and to extract the relevant information from it. Monitoring: Responding to specific tasks in terms of continuous monitoring and surveillance in many different application frameworks: improved management of logistics in storage warehouses, counting of people during event gatherings, monitoring of subway stations, coastal areas, etc. Computer Vision applications When considering a Computer Vision application, it’s important to ensure that the rest of the infrastructure in the Operation Center, for example the solution that drives the displays and video walls, will connect and work well with the computer vision application. The best way to do this of course is to use a software-driven approach to displaying information and data, rather than a traditional AV hardware approach, which may present incompatibilities. Software-defined and open technology solutions Software-defined and open technology solutions provide a wider support for any type of application the SOC may need Software-defined and open technology solutions provide a wider support for any type of application the SOC may need, including computer vision. In the modern world, with everything going digital, all security services and applications have become networked, and as such, they belong to IT. AV applications and services have increasingly become an integral part of an organization’s IT infrastructure. Software-defined approach to AV IT teams responsible for data protection are more in favor of a software-defined approach to AV that allow virtualised, open technologies as opposed to traditional hardware-based solutions. Software’s flexibility allows for more efficient refreshment cycles, expansions and upgrades. The rise of AV-over-IP technologies have enabled IT teams in SOC’s to effectively integrate AV solutions into their existing stack, greatly reducing overhead costs, when it comes to technology investments, staff training, maintenance, and even physical infrastructure. AV-over-IP software platforms Moreover, with AV-over-IP, software-defined AV platforms, IT teams can more easily integrate AI and Computer Vision applications within the SOC, and have better control of the data coming in, while achieving true situational awareness. Situational awareness is all about actionable data delivered to the right people, at the right time, in order to address security incidents and challenges. Situational awareness is all about actionable data delivered to the right people Often, the people who need to know about security risks or breaches are not physically present in the operation centers, so having the data and information locked up within the four walls of the SOC does not provide true situational awareness. hyper-scalable visual platforms Instead there is a need to be able to deliver the video stream, the dashboard of the data and information to any screen anywhere, at any time — including desktops, tablets phones — for the right people to see, whether that is an executive in a different office or working from home, or security guards walking the halls or streets. New technologies are continuing to extend the reach and the benefits of security operation centers. However, interoperability plays a key role in bringing together AI, machine learning and computer vision technologies, in order to ensure data is turned into actionable data, which is delivered to the right people to provide ‘true’ situational awareness. Software-defined, AV-over-IP platforms are the perfect medium to facilitate this for any organizations with physical and cyber security needs.

Securing Mobile Vehicles: The Cloud and Solving Transportation Industry Challenges
Securing Mobile Vehicles: The Cloud and Solving Transportation Industry Challenges

Securing Intelligent Transportation Systems (ITS) in the transportation industry is multi-faceted for a multitude of reasons. Pressures build for transit industry players to modernise their security systems, while also mitigating the vulnerabilities, risks, and growth-restrictions associated with proprietary as well as integrated solutions. There are the usual physical security obstacles when it comes to increasingly integrated solutions and retrofitting updated technologies into legacy systems. Starting with edge devices like cameras and intelligent sensors acquiring video, analytics and beyond, these edge devices are now found in almost all public transportation like buses, trains, subways, airplanes, cruise lines, and so much more. You can even find them in the world’s last manually operated cable car systems in San Francisco. The next layer to consider is the infrastructure and networks that support these edge devices and connect them to centralized monitoring stations or a VMS. Without this layer, all efforts at the edge or stations are in vain as you lose the connection between the two. And the final layer to consider when building a comprehensive transit solution is the software, recording devices, or viewing stations themselves that capture and report the video. The challenge of mobility However, the transportation industry in particular has a very unique challenge that many others do not – mobility. As other industries become more connected and integrated, they don’t usually have to consider going in and out or bouncing between networks as edge devices physically move. Obviously in the nature of transportation, this is key. Have you ever had a bad experience with your cellular, broadband or Wi-Fi at your home or office? You are not alone. The transportation industry in particular has a very unique challenge that many others do not – mobility Can you trust these same environments to record your surveillance video to the Cloud without losing any frames, non-stop 24 hours a day, 7 days a week, 365 days a year? To add to the complexity – how do you not only provide a reliable and secure solution when it’s mobile, traveling at varying speeds, and can be in/out of coverage using various wireless technologies? Waiting to upload video from a transport vehicle when it comes into port, the station, or any centralized location is a reactive approach that simply will not do any longer. Transit operations require a more proactive approach today and the ability to constantly know what is going on at any given time on their mobile vehicles, and escalate that information to headquarters, authorities, or law enforcement if needed; which can only occur with real-time monitoring. This is the ultimate question when it comes to collecting, analyzing, and sharing data from mobile vehicles – how to get the video from public transportation vehicles alike to headquarters in real time! Managing video data In order to answer this question, let’s get back to basics. The management and nature of video data differs greatly from conventional (IT) data. Not only is video conducted of large frames, but there are specific and important relationships among the frames and the timing between them. This relationship can easily get lost in translation if not handled properly. This is why it’s critical to consider the proper way to transmit large frames while under unstable or variable networks. The Internet and its protocols were designed more than two decades ago and purposed for conventional data. Although the Internet itself has not changed, today’s network environments run a lot faster, expand to further ranges, and support a variety of different types of data. Because the internet is more reliable and affordable than in the past some might think it can handle anything. However, it is good for data, but not for video. This combination makes it the perfect time to convert video recording to the Cloud! Video transmission protocol One of the main issues with today’s technology is the degradation of video quality when transmitting video over the Internet. ITS are in dire need for reliable transmission of real-time video recording. To address this need a radical, yet proven, video transmission protocol has recently been introduced to the market. It uses AI technology and to adapt to different environments in order to always deliver high quality, complete video frames. This protocol, when equipped with encryption and authentication, enables video to be transmitted reliably and securely over the Internet in a cloud environment. One of the main issues with today’s technology is the degradation of video quality when transmitting video over the Internet Finally, transportation industry has a video recording Cloud solution that is designed for (massive) video that can handle networks that might be experiencing high error rate. Such a protocol will not only answer the current challenges of the transportation industry, but also make the previously risky Cloud environment safe for even the most reserved environments and entities. With revolutionary transmission protocols, the time is now to consider adopting private Cloud for your transportation operations.
