Bosch CCTV Camera wipers, demisters & heaters  (6)

The term ‘marine’ comes from the Latin mare, meaning sea or ocean, and marine habitats can be divided into two categories: coastal and open ocean. Video surveillance (VS) applications can cover both types of marine environment with system for ships, maritime ports, onshore and offshore installations, etc. We should want to further analyse VS for ships and try to explain the types of ships on which it can be used, the ways in which VS can be used on ships, the typical certifications in use and what features a camera station must have to be installed on a ship. Starting with ships that have a minimum tonnage, around the world we have: liquefied natural gas (LNG) tankers, passengers ships, chemical tankers, crude oil tankers, container ships, general cargo ships and bulk carriers.As the LNG market grows rapidly, the fleet of LNG carriers continues to experience tremendous growth, offering more opportunities for VS Video surveillance for all marine vessels An LNG carrier is a tank ship designed for transporting liquefied natural gas. As the LNG market grows rapidly, the fleet of LNG carriers continues to experience tremendous growth. A passenger ship is a merchant ship whose primary function is to carry passengers by sea. This category does not include cargo vessels which have accommodation for a limited number of passengers, but rather includes the likes of ferries, yachts, ocean liners and cruise ships. A chemical tanker is a type of tank ship designed to transport chemicals in bulk. These ships can also carry other types of sensitive cargo which require a high standard of tank cleaning, such as palm oil, vegetable oils, tallow, caustic soda and methanol. An oil tanker, also known as a petroleum tanker, is a merchant ship designed for the bulk transport of oil. There are two basic types of oil tankers: crude tankers and product tankers. Crude tankers move large quantities of unrefined crude oil from its point of extraction to refineries. Product tankers, generally much smaller, are designed to move refined products from refineries to points near consuming markets. Container ships are cargo ships that carry their entire load in truck-size intermodal containers: a technique called containerisation. They are a common means of commercial intermodal freight transport and now carry most seagoing non-bulk cargo. Today, about 90% of non-bulk cargo worldwide is transported by container. A cargo ship or freighter ship is any sort of ship or vessel that carries cargo, goods and materials from one port to another. Cargo ships are specially designed for the task, often being equipped with cranes and other mechanisms to load and unload, and come in all sizes. Bulk carriers make up 15%–17% of the world's merchant ships and they are specially designed to transport unpackaged bulk cargo such as grains, coal, ore and cement in its cargo holds. For all these ships the protection of vessels, cargo and crew is a priority, that’s why the adoption of VS technology plays a key part in terms of security and safety. Human error is regularly named as a major factor in ship accidents, and one way to avoid it is to aid seafarers by providing them with technology and equipment that is reliable and easy to use in all weather and sea conditions. Marine VS encompasses liquefied natural gas (LNG) tankers, passengers ships, chemical tankers, crude oil tankers, container ships, general cargo ships and bulk carriers Emergency security solutions on ship One of the most important applications for camera stations is during “docking”. Mooring is the securing or confining of a vessel in a particular location with a fixed or a floating object (jetty, pier, ship, barge, buoy, etc.) as various cargo operations are carried out. Docking is the final stage of mooring operations when the ship docks to the jetty. This is a very delicate operation and cameras are very helpful in making sure docking is done without accidents.'Man overboard’ is an emergency in which a person has fallen off a boat or ship into the water, and can happen at any time during the day or night Another important application for camera stations is the Man Overboard detection system (MOB). ‘Man overboard’ is an emergency in which a person has fallen off a boat or ship into the water. Man overboard events can happen at any time during the day or night, in all types of weather and sea conditions, and from almost any location on the ship, ranging from a few tens of feet above the water, to over 180 feet.  When these events occur, the immediate availability of important data is crucial. Accurate confirmation of the event including time of occurrence, location on the ship and location in the sea is critical. A proactive detection system must immediately and accurately detect man overboard events and provide prompt, actionable data to response personnel. A typical man overboard detection system can report a MOB event in under 1 second. VS on a vessel can also monitor the engine room at all times and provide a good view of people working on dock, machinery and stowed equipment. But what are the most important features that a camera station must have to work in one of the most aggressive environments in nature? Marine surveillance must operate in one of the most harsh environments in nature Ruggedised reliability in surveillance First of all, and perhaps it’s obvious, but it’s extremely important to have camera stations with amazing reliability. Housing units manufactured from AISI 316L stainless steel, passivated and electropolished, makes the cameras completely impervious to air, water, rusting and corrosion, therefore offering excellent weather protection and increased reliability. Housing units manufactured from AISI 316L stainless steel, passivated and electropolished, makes the cameras completely impervious to air, water, rusting and corrosion Sometimes ships also use cameras constructed entirely from technopolymer, which guarantees high impact resistance and superior protection from external weather agents. Keeping the camera glass clean at all times is another essential feature, and it can be done via a wiper/wash system that greatly reduces the need for maintenance. In the case of PTZ cameras, the best option would be a great pan and tilt speed (up to 100°/s). What is the operative temperature range for the cameras? Sea is everywhere and therefore ships go everywhere, from the Arctic Ocean to the Mediterranean, so we need cameras that have to be fully operational across a wide temperature range.  -40°C to +65°C covers almost all areas. Analogue or IP Cameras? Actually, both options can be used, especially for applications like docking where it’s important to avoid image delay (as can happen with IP cameras due to the natural latency of data communication over a network). Marine certifications Last but not least, the certifications: Certifications guarantee the quality and reliability of camera stations. There is no compromise! One important certification is the Lloyd’s Register Type Approval which subjects cameras to rigorous testing for performance, vibration (critical on ships), humidity, etc. The application field of the LR Type Approval is VS in public places (e.g. passenger ships), open decks, enclosed spaces that are subjected to heat generated from other equipment, and technical premises. Often, VS cameras used in specific areas of ships, such as hazardous areas, are required to have ATEX and IECEX certifications.

Standards for camera manufacturers presented a new challenge with the introduction of security cameras that require more than 30 Watts of power Standards for camera manufacturers presented a new challenge with the introduction of security cameras that require more than 30 Watts of power. Many of these involve pan-tilt-zoom (PTZ) domes and heaters and blowers that require additional power. This development created two areas of confusion which is highlighted in this article by Neil Heller - Vice President, Vigitron. The first is the ability to define what a 60-watt camera is and what power sources are actually required. The second and more serious is how to provide that power. Both share a commonality in that they lack any form of standardisation. PoE to power 60-watt security camera alone? Let’s start with the definition of the 60-watt camera. As the term suggests, it requires 60 watts or greater, but that doesn’t necessarily mean all the required power comes from a single PoE source. In many cases, camera manufacturers require that PoE only power the camera itself. Looking at these cameras’ power specifications will indicate a required PoE power of 802.3at or 30 watts, thus leaving power to the heaters and blowers requiring a local AC power source. This situation brings into question the value of PoE power if it is restricted to only providing camera power. Another group of PTZ cameras does use PoE for both camera and heater/blower functions, but only when the heater operates within a restricted temperature range. This usually means if your camera is installed in areas where the temperature that can fall below -20 degrees C (approximately -20 degrees F) you will still need a local power AC power source. The third type of security camera relies only on PoE power for both PTZ and heater blower operations.  This is confusing, and is often the source of users finding their PTZ has failed at the most inopportune time. Any attempt to transmit 60 watt power over coax cable that is only a single pair should be considered with a great deal of caution, requesting from the transmission equipment provider that they will accept liability for any damages PoE for greater than 30 Watt applications The three different operations of how these “PoE” cameras are powered brings into question the value of using PoE for greater than 802.3at, 30 Watt applications. Value exists in the ability to centrally control power operations from a single accessible point. Certainly those cameras that are solely dependent upon PoE have the greatest advantage. This brings to the second point of confusion, the composition of the PoE power. To review a brief history, 802.3af (15.4) was the first PoE standard used for IP cameras and is for the most part a standard. 802.3at (30 Watts) was introduced as four different standards, two of which, Type 1 and Type 2 are supposed be compatible, but in reality are not.     Transmission restriction over physical cables 60 watts has no standards. To understand this, we need to look at the limitations of transmitting power over physical cables. Any form of transmission over a physical media has limitations in the form of resistance. As resistance increases, so does the heat generated by this process. The higher the power, the greater the resistance and resulting heat generated. Based on CAT5e cable, a single wire can handle about 0.75 amps. In PoE transmission, power is transmitted on a pair of wires or 0.75amp X 2= 1.5amps.  According to the 802.3at specifications, Class 4 specifications generally are considered to start around 48 volts. So we take 48 x 0.75= 36 watts or 72 watts for the pair. Dual PD (power device) system So how do we get to 60 watts? For “over” 30 watts, camera manufacturers use a dual PD (power device) system. In short, it operates as if it where two IP cameras and requires use of all four pairs within Cat cabling. Exceeding these power limits can be dangerous in overheating the cable and its installation. Therefore, any attempt to transmit 60 watt power over coax cable that is only a single pair should be considered with a great deal of caution, requesting from the transmission equipment provider that they will accept liability for any damages. The need to operate two PDs within a single camera is where the incompatibility exists. There are no standards as to the sequence of turning on  separate PDs in a single camera The need to operate two PDs within a single camera is where the incompatibility exists. There are no standards as to the sequence of turning on separate PDs in a single camera. Most such camera manufacturers provide their own PoE source in the form of a PSE or camera power supply; however, don’t try to interchange these power sources among different cameras from different manufacturers as they will not work. If you attempt to use a third party version, make certain you confirm that the power source manufacturer has actually conducted certification testing and can provide proof of compatibility or provide any operational limitations. Distance of transmission Finally, there is the question of transmission distance. This takes us back to the physics of high-powered PoE transmission. Even with manufacturer-supplied PSEs, the distance limitation is still 328 feet (100m), the Ethernet standard. Most applications such as perimeter and parking lots will be hard pressed to find a power outlet within 328 feet of where the cameras needs to be installed. This is where third-party transmission equipment providers come into play, but again the ability of transmitting 60 watts PoE power for distances greater than 328 is more complex that standard 802.3af and 802.3at, and more limited. This combined with the non-standard make a detailed knowledge and interaction with the manufacturer critical to a successful installation.

Q: Mr. Seiter, Mr. Ekerot, you both joined Bosch Building Technologies’ business unit Video Systems & Solutions as Senior Vice Presidents in March 2020, when the Coronavirus pandemic was just beginning. How did your business unit get through 2020? Magnus Ekerot: The crisis was also felt at Bosch. At the same time, demand has risen for solutions that keep businesses open and protect people's health. We offer corresponding video solutions that can make a significant contribution to containing the pandemic.  Michael Seiter: Overall, we managed the past year well despite the challenges and have been growing again since the third quarter compared to 2019. We see good opportunities for further growth in 2021. Q: Has the Corona crisis again accelerated the development of smart technologies in the security technology market, and does the security market in contrast to most industries benefit from the crisis more than it suffers? Michael Seiter: The Corona crisis has definitely demonstrated that the future lies in data-driven solutions. Thanks to our product development strategy already being based on this, we at Bosch were very quickly able to develop new products for the ‘New Normal’ and to expand existing products accordingly. To give one or two examples: in cooperation with Philips, we very quickly developed a people counting solution for retail operations – smart Philips displays in conjunction with smart cameras from Bosch that provide protection for staff and customers. The In-Store Analytics software solution was also implemented with additional features. Shop owners can now make decisions based on customer movement data such as “Where do we position products to avoid queues or crowds?” HTD involves a touch-free monitoring system to accurately and speedily identify people with heightened skin temperature  The latest highlight is the Bosch Human Skin Temperature Detection solution, in short HTD. This involves a touch-free monitoring system to accurately and speedily identify people with heightened skin temperature at control points in offices, factory floors, or airports. The benefits of previously existing solutions on the market are sometimes called into question. Competitors are often unable to deliver what they promise because, for example, the measured temperature of the skin does not correspond to the core temperature of the person, or fluctuates, due to environmental influences. Therefore, we developed a software-based solution that, in compliance with GDPR, first allows people with potentially elevated body temperatures to be filtered out, and in a second step, allows medical personnel to perform a more targeted fever measurement. Q: You see a lot of potential for the video security industry in new technologies such as Artificial Intelligence and the Internet of Things. What specific opportunities do you mean, and how are you leveraging these technologies at Bosch Building Technologies? Michael Seiter: Bosch has committed itself fully to an “AIoT” – AI meets IoT – strategy. The development of AI algorithms and software, in general, is at Bosch significantly driven in the security space.  By AIoT, we specifically mean the networking of physical products and the deployment of artificial intelligence. With AI we aim to enable clients to understand events at an ever-deeper level and predict them in the future – the keyword being predictive – so that they can act proactively. This is particularly important for health and safety. An example is the Intelligent Insights solution where the user can anticipate potentially dangerous situations, for instance in maintaining social distance and a maximum number of people numbers in any one area. Q: From your point of view do you have an advantage over other suppliers when it comes to AI-based products in the video arena? Michael Seiter: The analysis and utilisation of video data have long been front and centre with us. Since 2016 we’ve been following the strategy of offering AI applications in the form of integrated intelligent video analytics as a standard in our network cameras. Data such as colour, object size, object speed, and direction are all measured. Simply put, you can say this is seeing and understanding – which is the principle behind smart security cameras. Today it’s much more a question of intelligent, data-based solutions than collecting high-quality pictures and storing them for the record. Bosch has been investing heavily in AI for years, from which we can benefit greatly in our area. In the first quarter, for example, we will launch a vehicle detector based on deep learning that is already running on our cameras. This will create significant added value for our customers in the area of intelligent traffic control. Q: Mr. Ekerot, what advantages do customers have in AI-based video security from Bosch? Magnus Ekerot: A key advantage is strong customer focus with tailored solutions that are at the same time modular and scalable through new AI algorithms A key advantage is our strong customer focus with tailored solutions that are at the same time modular and scalable through new AI algorithms. Take the example of Camera Trainer, a machine learning software that can be directly uploaded to Bosch network cameras. The camera is thus trained up on recognising objects and situations – tailored to the specific needs of our customers. If the camera detects the defined scenario, it performs a predefined action in real-time – for example, a count or an alarm. The latest example is our new camera platform Inteox. As a completely open camera platform, Inteox combines Bosch's intelligent video analytics with an open operating system. This allows programmers to develop specific software applications - or apps - for various application purposes. These can then be loaded onto cameras – the same principle as an app store for smartphones. To sum up, Bosch AI applications support customer-specific needs related to data analysis while enabling totally new applications within and beyond the video security market. Q: Can you name a specific current project where Bosch has deployed an AI-based solution? Magnus Ekerot: A current ground-breaking project using our smart cameras is being implemented as a pilot in the USA. Smart Ohio enables users to configure more intelligent traffic flows and thus ensure mobility, safety, and the efficient use of roads today and tomorrow. The new vehicle detector mentioned by Mr. Seiter also plays a central role here. Our overall goal is to provide connected smart sensor solutions for public and private transportation agencies to enable them to operate their roads safely and efficiently. The Intelligent Insights can anticipate potentially dangerous situations, for instance in maintaining social distance and a maximum number of people numbers in any one area Q: Mr. Seiter, you have been involved with the topic of mobility for some time. What experience from your previous job in the automotive business of Bosch might help you when it comes to further develop the video portfolio of Bosch Building Technologies? Michael Seiter: There's a lot to tell. First of all, the development of core algorithms for video-based solutions, whether for autonomous driving, for vehicle interior monitoring, or for our Bosch Building Technologies video systems, all come together at Bosch's Hildesheim location. This gives us considerable synergies and allows us to bring R&D results to market faster and more flexibly. Essentially, assisted driving systems use AI algorithms that process ever-increasing volumes of video data. Attempts are being made to imitate the human being and enable the vehicle to understand better the surrounding environment with its ‘eyes’. This predictive capability is especially critical with autonomous driving. For example, key questions include: “How should the car respond and what could potentially happen next?” “What kind of environment does it find itself in?” etc. There are many activities in this area at Bosch that in my new role in security we can also strongly benefit from. I am now bringing a lot of this experience and existing R&D achievements to Bosch Video Systems & Solutions, which also results in further synergies with our mobility division: At Stuttgart Airport, autonomous driving is already being implemented together with Mercedes-Benz and the parking garage operator Apcoa as part of the "Automated Valet Parking" project, or AVP for short, in which intelligent video systems from Bosch Building Technologies are making a significant contribution. Mr. Ekerot, you have a lot of experience in the video security area. Where do you position Bosch Building Technologies now in this market and what specific goals are you pursuing? Magnus Ekerot: Our clients are looking for reliable partners and products. We are a strong brand; you can rely on Bosch products. Bosch is a thought leader in video and a pioneer in AI applications in this field since 2016. Data security is everything to us: Our products conform to the EU’s GDPR regulations. Beyond that, we have an extensive camera portfolio that complies with the US National Defense Authorization Act (NDAA) for video security devices. This enables our portfolio to be deployed for example within US government buildings. We are planning to conclude more software maintenance agreements with our clients in 2021. These deliver investment and future security for our customers and include for example a ‘patch guarantee’ along with regular updates with new functionalities. This is the first step in a comprehensive plan to access new revenue channels for us and our partners delivering the best technology and excellent service to the end-user! Overall, many new products will be launched this year and this trend will intensify. Our goal is to establish new product families that follow a simple principle: “The development and delivery of disruptive, predictive video solutions that every user can trust because of the underlying sustainable forward-thinking mindset.” It’s been much discussed of late that Bosch is one of the very first companies globally that operates on a CO2-neutral basis. How does sustainability impact your business? Magnus Ekerot: IoT solutions are actually sustainable and contribute to environmental protection Our IoT solutions are actually sustainable and contribute to environmental protection. For example, our cameras are sustainable in that they remain up-to-date through software updates and needn’t be constantly exchanged for new ones. Our systems demonstrate sustainability also operationally as they can be managed remotely. System integrators don’t need to be physically present, thus avoiding unnecessary travel with its accompanying emissions. All in all, Bosch Building Technologies develops ways to accompany and support our clients in reaching their climate goals via new technologies. This can be done, for example, through improved energy efficiency, the total cost of ownership models, organising and simplifying the supply chain, and helping our customers meet their social responsibilities. The Power of Bosch helps us here to leverage company-wide research to be two steps ahead, a shade faster, when it comes to new technologies and initiatives that our and future generations will benefit from. I should also say that I am personally very proud to work for a company that set an ambitious climate goal for itself and achieved it! Can you already share a preview of your technology innovations in 2021? Michael Seiter: We see great market potential for our cameras that use artificial intelligence and can be updated flexibly throughout their lifecycles. I have already mentioned the deep learning-based vehicle detector in our cameras. More such solutions – also for other applications where object and person recognition are important – will follow in the course of the year. And the best part is: with AI, the more data we collect and the more intelligently we use it, the better the solutions become and the more added value they bring to the customer. This will revolutionise our industry! Another example is our cloud-based solutions, for example for alarm monitoring. Here, we can now also integrate third-party cameras and, building on this, offer and jointly develop our intelligent software-based solutions. This gives our customers more opportunities to take advantage of the opportunities created by AI. The trend towards integration of the various security technologies seems to be driven mostly by the rapid progress in software development. Does this affect full-range suppliers such as Bosch and what specific plans for fully integrated security solutions do you have for the future? Michael Seiter: Naturally, this suits us as a full-scope supplier. Bosch solutions are deployed in many cross-domain client projects. We have experts for the different domains under one roof and a strong brand with the same quality promise for all areas. Nevertheless, it is always also about specific domain excellence. Only when you master all different areas and have profound and proven expertise in each of them you can succeed in integrated cross-domain projects. The respective business units craft their future strategies and innovation roadmaps with this in mind – as we do in the field of Video Systems & Solutions. Our business unit offers fully integrated Bosch video solutions that can be extended and operated on open systems. This is why we drive open platforms such as Inteox, to offer customers from a wide range of industries the right solutions. Our Bosch Integration Partner Program that we launched in 2012 is also heading in this direction – every product can be integrated into multiple other systems and VMS solutions. In summary: At Bosch, we are both a one-stop-shop, but also an open-system, meaning we offer customers maximum flexibility in their choice of products and services.

Bosch introduces the first cameras based on its Inteox open camera platform starting with the MIC inteox 7100i. The new MIC inteox cameras share the same distinctive characteristics as the rest of the MIC camera family, such as robust housing and high-quality imaging, and support predictive solutions with machine learning, neural network-based video analytics, and third-party software apps for customised applications. These Inteox cameras can be classified as ‘Driven by OSSA.’ This distinction signifies that the cameras follow the Open Security & Safety Alliance (OSSA) Technology Stack for video security devices, ensuring seamless connectivity with the Security & Safety Things (S&ST) application store. Developing software apps The cameras also allow for the easy creation of customised software apps that can be deployed on the Inteox cameras afterward. Market players can mix and match apps from the S&ST Application Store or develop software apps to create a novel solution. In addition, Bosch introduces two Inteox development kits containing either a bullet camera or mini-dome camera to complement MIC inteox cameras in pilot installations and support further app development. MIC inteox 7100i cameras support predictive solutions with built-in artificial intelligence (AI) MIC inteox 7100i cameras support predictive solutions with built-in artificial intelligence (AI). It includes Intelligent Video Analytics, Camera Trainer based on machine learning, and video analytics based on deep neural networks (DNN). These built-in AI capabilities enable Inteox cameras to understand what they see and add sense and structure to captured video data with metadata. Building predictive solutions This process is an important first step in converting video data into actionable insights and building predictive solutions, helping users anticipate unforeseen events and prevent them from happening. For example, in city surveillance applications, the MIC inteox 7100i cameras can detect abnormalities in behaviours, provide density data, and alert traffic operators with insights they can act on to prevent unwanted situations. By adding third-party software apps to Inteox cameras, integrators can easily customise security systems, enabling them to go beyond their basic functionality. In turn, app developers can leverage the camera's metadata, neural network-based video analytics, and machine learning to introduce innovative software to the market. The MIC inteox 7100i object classification (OC) models are made specifically for Intelligent Transportation Systems (ITS) applications. Powered by the edge computation capabilities of the Inteox platform, the introductory OC models present a novelty in the field of AI. Various traffic applications Possible disturbances caused by vehicle headlights or shadows are ignored They offer a Traffic Detector, an additional Video Analytics feature based on DNN that helps distinguish and classify automobiles in congested scenes with precise detail. Possible disturbances caused by vehicle headlights or shadows are ignored, uncovering new ways to improve mobility, safety, and efficient use of roadways. The actionable insights delivered by the cameras’ Traffic Detector help detect the presence and volume of vehicles to intelligently control traffic lights to keep traffic flowing when monitoring intersections. These insights can also enhance Automatic Incident Detection (AID) solutions to improve the safety of people and vehicles in tunnels and on highways. Future OC models planned for June 2021 will expand upon these DNN-based features offering greater granularity of data when generating actionable insights for various traffic applications. Optical image stabilisation MIC inteox cameras range from a 4K enhanced model featuring optical image stabilisation to a 1080p model in a base or enhanced version featuring Bosch’s starlight technology that can capture colour images down to a level of 0.0069 lux as standard. The 4K model's optically-stabilised images maintain pin-sharp pictures even when the camera is subject to severe vibration, such as on bridges. With the optional illuminator, the 4K model covers a distance of 300m (984 ft.) The 1080p models feature 30x zoom and a frame rate of 60 frames per second. When light levels drop to zero, the optional illuminator ensures the greatest level of detail over a distance of up to 550m (1,804 ft.). Enhanced versions for both 4K and 1080p models also include an in-window defroster to improve visibility and onboard storage capabilities. Meeting marine requirements The MIC inteox 7100i features rugged housing with superior metallurgy and finish to protect against corrosion Combined with robust housing, the cameras provide the high-quality details required by applications such as city surveillance, traffic monitoring, and perimeter security. Like all MIC cameras, the MIC inteox 7100i features rugged housing with superior metallurgy and finish to protect against corrosion, including salt-water, to meet marine requirements. Engineered to endure nearly everything from high winds, rain, fog, and dust, MIC cameras can withstand 100% humidity, temperatures from -40°C to +65°C (-40°F to +149°F), extreme vibrations, and high impacts (IK10). Slow-moving targets What’s more, a new drive train enables them to track slow-moving targets as smoothly as possible. The cameras are guaranteed never to lose their homing position, returning to a preset position over their entire lifetime, even when exposed to extreme vibration or brute force. Early adopters can take advantage of Bosch Inteox development kits to complement the MIC inteox 7100i cameras in pilot installations. The kits contain either a Bosch fixed bullet (Dinion) or mini-dome (Flexidome) outdoor camera that will run on the S&ST operating system. Both kits support the testing and development of an overall system solution based on apps already available through the application store and self-developed apps.

Bosch Building Technologies has installed an intrusion alarm system at the UNESCO World Heritage Site: the Mausoleum of Qin Shihuangdi in the city of Xi'an, China. Several hundred TriTech motion detectors are deployed to protect the 16,300-square-foot museum against theft and damage. These detectors prevent costly and time-consuming false alarms under challenging environmental conditions while providing detection reliability of real alarms. Because of the highly efficient intrusion detection system, the museum can dispense entirely with physical protective barriers such as glass walls, allowing visitors to directly experience their clay heroes. “The cooperation with Bosch is an excellent showcase of modern high-tech protection of historic buildings. Bosch intrusion alarm systems help to upgrade the security level of these unique historic sites,” says Ren Xuxin, Project Manager of Xi’an Terracotta Warriors and Horses Pit Security Upgrade Project. Intelligent alarms protect millennia-old warriors As wall detectors, the TriTech motion detectors protect the pits where the terracotta warriors are located. Because these pits collect large amounts of dust that could cause false alarms, the intelligent sensor data fusion algorithm in each of the rugged detectors checks potential alarms with a PIR sensor and microwave Doppler radar for a consistent result. The area to be protected is thereby also secured from above by ceiling-mounted TriTech motion detectors. These detectors are located 4.8 metres above the museum floor, yet operate accurately and reliably. They thus exceed the range of standard ceiling detectors by more than two metres. The TriTech motion detectors provide round-the-clock protection for the museum In the event of a security breach, the Bosch G-Series system controller sends an alert, including the location of the triggered detector, in less than two seconds to the security team in the control room, which uses live images from a video system to verify the alarm. Round-the-clock protection In most cases, tourists trigger an alarm when they cross a threshold to retrieve their cameras or smartphones that have accidentally fallen into the pit. In doing so, there is a risk of damage to the terracotta warriors, but even if real criminals should ever get into the act, the system is ready. The TriTech motion detectors provide round-the-clock protection for the museum. Due to their discreet design, the detectors are unobtrusive and thus do not interfere with the museum experience. In accordance with the museum operator's list of requirements, the intrusion detection system protects not only the museum, including the perimeter, as well as the visitor areas of the mausoleum but additionally the cultural treasures currently stored in the unmanned warehouse.
