Live-streaming mobile surveillance takes cameras to the action
Live-streaming mobile surveillance takes cameras to the action

Video surveillance across the world is growing exponentially and its major application is in both public safety and law enforcement. Traditionally, it has been fixed surveillance where cameras provide live streams from fixed cameras situated in what is considered strategic locations. But they are limited in what they can see given by their very definition of being "fixed." The future of video surveillance includes the deployment of more mobile video surveillance with the benefits it offers. Instead of fixed cameras, this is the ability to live stream from mobile devices on the move such as body-worn cams, drones, motorbikes, cars, helicopters and in some cases, even dogs!Sending drones into the air, for example for missing people or rescue missions, is much more cost-effective than deploying helicopters Advantages of mobile surveillance The advantage of mobile surveillance is that the camera can go to where the action is, rather than relying on the action going to where the camera is. Also, sending drones into the air, for example for missing people or rescue missions, is much more cost-effective than deploying helicopters. The ability to live stream video from cars and helicopters in high-speed pursuits can be used to take some of the operational issues from the first responders on the ground and share that “life and death” responsibility with the operational team leaders back in the command centre. This allows the first responders in the pursuit vehicle to focus on minimising risk while staying in close proximity of the fleeing vehicle, with direction from a higher authority who can see for themselves in real time the issues that are being experienced, and direct accordingly. In addition to showing video live stream from a pursuit car or motorcycle, by using inbuilt GPS tracking, the video can be displayed on a map in real time, allowing a command chief to better utilise additional resource and where to deploy them, through the use of displaying mapping information with real time video feed. It allows police chiefs to make better informed decisions in highly-charged environments. The 4G phone network can now be used with compressed video to live stream cost effectively Application in emergency situations The same is true of first responders in many different emergency situations. Mobile surveillance opens up a new area of efficiencies that previously was impossible to achieve. For example, special operations can wear action body-worn cameras when doing raids, fire departments can live stream from emergency situations with both thermal and daylight cameras, and paramedics can send video streams back to hospitals allowing doctors to remotely diagnose and prepare themselves for when patients arrive at the hospital. How can special operations and emergency first responders live stream video from a mobile camera with the issues of weight, reliability and picture-quality being considered? H265 mobile video compression Law enforcement insists on secure transmissions, and it is possible to encrypt video to the highest level of security available in the public domain The 4G phone network can now be used with compressed video to live stream cost effectively. The issue of course is that 4G is not always reliable. Soliton Systems has mitigated this risk of low mobile quality in certain areas, by building an H265 mobile video compression device that can use multiple SIM cards from different cellular providers simultaneously. H265 is the latest compression technique for video, that is 50% more effective than conventional H264, and coupling this with using multiple “bonded” SIM cards provides a highly reliable connection for live-streaming high-quality HD video. The 400-gram device with an internal battery can be connected to a small action cam, and can live-stream simultaneously over at least three different cellular providers, back to a command centre. Latency is typically less than a second, and new advance improvements are looking to reduce that latency further. Encrypted video transmission What about security? Law enforcement insists on secure transmissions, and it is possible to encrypt video to the highest level of security available in the public domain, i.e. AES256.What about integration into existing video infrastructure at the command centre? It is not untypical for a police force to have an existing video management system (VMS) at their command centre such as Milestone System’s Xprotect. The Soliton range of products are ONVIF-compliant, a standard used by video surveillance cameras for interoperability, allowing cameras and video devices that are ONVIF-compliant to simply “plug&play” into existing video management systems. These mobile transmitters are deployed with law enforcement and first responders across the globe. Their ability to provide secure, full HD quality and highly-reliable video streaming within a small unit, and to enable it to be integrated into the current eco-system that is already installed at the receiving end, has made them a favourite choice with many companies and government agencies.

Why live video streaming is critical for safer and smarter cities
Why live video streaming is critical for safer and smarter cities

The term “smart city” gets thrown around a lot nowadays, but as different technologies that strive to be defined in this way are adopted by different countries globally, the meaning of this phrase gets lost in translation. The simplest way to define a “smart city” is that it is an urban area that uses different types of data collecting sensors to manage assets and resources efficiently. One of the most obvious types of “data collecting sensor” is the video camera, whether that camera is part of a city’s existing CCTV infrastructure, a camera in a shopping centre or even a police car’s dash camera. The information gathered by video cameras can be used with two purposes in mind, firstly: making people’s lives more efficient, for example by managing traffic, and secondly (and arguably more importantly): making people’s lives safer. Live streaming video all the time, everywhere In the smart and safe city, traditional record-only video cameras are of limited use. Yes, they can be used to collect video which can be used for evidence after a crime has taken place, but there is no way that this technology could help divert cars away from an accident to avoid traffic building up, or prevent a crime from taking place in the first place. However, streaming live video from a camera that isn’t connected to an infrastructure via costly fibre optic cabling has proven challenging for security professionals, law enforcement and city planners alike. This is because it isn’t viable to transmit video reliably over cellular networks, in contrast to simply receiving it. Video transmission challenges Transmitting video normally results in freezing and buffering issues which can hinder efforts to fight crime and enable flow within a city, as these services require real-time, zero latency video without delays. Therefore, special technology is required that copes with poor and varying bandwidths to allow a real-time view of any scene where cameras are present to support immediate decision making and smart city processes. The information gatheredby video cameras can beused to make people’s lives more efficient, and to make people’s lives safer There are many approaches to transmitting video over cellular. We’ve developed a specialist codec (encoding and decoding algorithm) that can provide secure and reliable video over ultra-low bandwidths and can therefore cope when networks become constrained. Another technique, which is particularly useful if streaming video from police body worn cameras or dash cams that move around, is to create a local wireless “bubble” at the scene, using Wi-Fi or mesh radio systems to provide local high-bandwidth communications that can communicate with a central location via cellular or even satellite communications. Enhanced city surveillance Live video streaming within the smart and safe city’s infrastructure means that video’s capabilities can go beyond simple evidence recording and evolve into a tool that allows operations teams to monitor and remediate against incidents as they are happening. This can be taken one step further with the deployment of facial recognition via live streaming video. Facial recognition technology can be added on to any video surveillance camera that is recording at a high enough quality to identify faces. The technology works by capturing video, streaming the live video back to a control centre and matching faces against any watch lists that the control centre owns. Importantly, the data of people who aren’t on watch lists is not stored by the technology. Identifying known criminals This technology can work to make the city safer in a number of ways. For example, facial recognition could spot a known drug dealer in a city centre where they weren’t supposed to be, or facial recognition could identify if a group of known terror suspects were visiting the same location at the same time, and this would send an alert to the police. Facial recognition technology captures and streams live back to a control centre, matching faces against any watch lists that the control centre owns In an ideal world where the police had an automated, electronic workflow, the police officer nearest to the location of the incident would be identified by GPS and would be told by the control room where to go and what to do. Most police forces aren’t quite at this technological level yet, and would probably rely on communicating via radio in order to send the nearest response team to the scene. As well as this, shopping centres could create a database from analogue records of known shoplifters to identify criminals as soon as they entered the building. This would be even more effective if run co-operatively between all shopping centres and local businesses in an area, and would not only catch any known shoplifters acting suspiciously, but would act as a deterrent from shoplifting in the first place. Live streaming for police As mentioned above, live streaming video from CCTV cameras can help the police fight crime more proactively rather than reactively. This can be enhanced even further if combined with live streaming video from police car dash cams and police body worn cameras. If video was streamed from all of these sources to a central HQ, such as a police operations centre, the force would be able to have full situational awareness throughout an incident. This would mean that, if need be, officers could be advised on the best course of action, and additional police or other emergency services could be deployed instantly if needed. Incorporated with facial recognition, this would also mean that police could instantly identify if they were dealing with known criminals or terrorists. Whilst they would still have to confirm the identity of the person with questioning or by checking their identification, this is still more streamlined than describing what a person looks like over a radio and then ops trying to manually identify if the person is on a watch list. The smart, safe city is possible today – for one, if live video streaming capabilities are deployed they can enable new levels of flow in the city. With the addition of facial recognition, cities will be safer than ever before and law enforcement and security teams will be able to proactively stop crime before it happens by deterring criminal activity from taking place at all.

Surge protection for security installations: 2017 saw increased investment
Surge protection for security installations: 2017 saw increased investment

In 2017, DITEK saw how power surges from the many natural disasters that took place damaged many businesses. In a natural disaster, or even everyday business operations, a facility’s entire investment in security, life safety and surveillance systems technology can be disabled or rendered useless in a few seconds. Surge protection solutions can mitigate those risks and protect security investments. Proactive approach to risk mitigation Throughout 2017, we also witnessed a change in how enterprises view surge protection, which included how investments are being made in surge protection to protect valuable security, life safety and surveillance systems, while also reducing downtime, manpower costs, liability vulnerabilities, and possibly compliance issues that can force businesses to actually cease operations. Effective security management is about mitigating risks. But risks cannot be mitigated without a proactive approach. Enterprises and integrators, who take the time to assess risk and to develop a strategy to incorporate effective detection, deter and response criteria to protect physical assets will be successful in 2018. 2018 and beyond That strategy includes designing surge protection into new security systems, while also adding surge protection to existing systems. Enterprises and security integrators who implement a surge protection strategy during security planning processes – or after – will be exercising prevention and mitigation, and they will be successful in 2018 and beyond.  Surge protection devices have an untapped potential for enterprise surveillance and security systems In 2017, Ditek continued to offer security end users a solid surge protection solution. We also successfully educated system integrators, who are seeking value-added products or services to incorporate into their portfolios, on the importance of surge protection devices. Educating security integrators We believe that surge protection devices have an untapped potential for enterprise video surveillance and security systems, because they can and do meet safety and security challenges that have been rarely identified in the past. We are looking forward to 2018, when we will continue to develop new surge protection products – including a new product engineered to protect up to twelve individual fuel dispensers, which is critical to the financial operation of convenience stores. We will also continue to educate security integrators about the importance of including surge protection in the design/build RFP, to not only secure an enterprise’s valuable security equipment, but also to help integrators to differentiate their capabilities and knowledge from the competition.

Bosch provides their Praesensa public address and voice alarm system at Wycombe Wanderers’ Adams Park stadium

The Praesensa public address and voice alarm system from Bosch is at the heart of the new safety system at Wycombe Wanderers’ Adams Park stadium. The football club chose for digital infrastructure design specialist and system integrator Landways to design, fund and install this new system, alongside high-performance solutions for Wi-Fi and security, to help realise owner Rob Couhig’s ambitious vision for a great match day experience. Digital message storage The stadium officials eventually decided on the fully IP-based Praesensa system from Bosch, which covers all public areas of the 10,000-capacity stadium and features a smart-power concept with integrated redundancies to save on energy, hardware and space. Supporting the required intelligibility for voice evacuation, the system assures security for fans, complying with the requirements set by both the English Football League and the local council for ground safety and survivability in the event of an emergency. The solution can be utilised for pre-recorded messages from the system controller’s digital message storage, or for live announcements from two Praesensa emergency call stations. Digital audio matrices Praesensa messages are always ready to broadcast at the highest priority The audio signals from Praesensa are fed into nine Dynacord MXE5 digital audio matrices via the built-in OMNEO IP architecture. This perfectly matches the benefits of a combined prosound and public address system with the mandatory requirements for voice alarm systems to be fully compliant to the required standards. Functioning as a communications hub, the MXE5 can be used for all peripherals, with comprehensive supervision and monitoring of all system-wide commands. The seamless integration of all IP-based systems ensures that during an emergency, Praesensa messages are always ready to broadcast at the highest priority, with the entertainment audio automatically muted. With reliability ensured from the moment of installation, the feature-rich Bosch Praesensa provides Adams Park with a future-proof solution that can be easily configured and controlled via the intuitive user interface. High-quality stadium “I am delighted that our new digital infrastructure is now fully in place and available for the benefit of everyone inside Adams Park,” says Rob Couhig, Chairman of Wycombe Wanderers. “We are making a long-term investment in IP technology to improve the match-day experience, reduce costs and help our business continue to thrive. It is great that the same underlying energy-efficient infrastructure that delivers our incredibly fast Wi-Fi can also be used to deliver high-quality stadium audio and new safety systems.”

The new Bosch Training and Experience Centre in Bentonville, Arkansas showcase immersive displays of the company’s latest offerings. Now open for private sessions, the centre offers demonstrations of how Bosch systems for video security, access control, intrusion and fire detection, and communications integrate seamlessly together to provide solutions that increase security and safety, facilitate more efficient monitoring and control, automate audio announcements, and provide data for business intelligence. Advanced security technology AIoT, which is the next-generation IoT combined with AI, is driving innovation in security technology" “AIoT, which is the next-generation Internet of Things (IoT) combined with artificial intelligence (AI), is driving innovation in security technology,” said Brian Wiser, President of Bosch Security and Safety Systems, North America. “Hands-on experience is vital to the adoption of these advanced technologies, and our new centre offers customers a private setting to explore solutions that can help them responds to possible risks before situations occur and gather business data for informed decision-making that goes beyond security.” Solution demonstrations Visitors to the centre will see how Bosch video cameras feature built-in AI to extend the devices beyond their traditional uses, including for improving health and safety in a facility. One demonstration simulates a blocked emergency exit door to show how Bosch AIoT cameras will trigger an alarm within the video management system, an event at a nearby intrusion system keypad, and a warning message to play in the area using a Bosch public address system. These actions triggered by the camera ensure the situation is resolved faster, improving safety. Tracking occupancy Bosch AIoT video systems installed in the centre also demonstrate how customers can track the occupancy of space for adhering to health and safety regulations, detecting crowds, or ensuring adequate staffing of a facility. Bosch Intelligent Insights software aggregates data, such as counts of people or vehicles, from multiple cameras to give users a complete view of a situation in real-time. This helps users react quickly to events that need to be addressed and make decisions based on the latest information. Video management system Demonstrations include solutions for securing high-risk areas, capturing data for business intelligence For retail stores, bank branches, and similar applications, visitors can see how pressing a cashier station panic button or pulling a bill from a bill trap sensor connected to the intrusion system will display an alarm and video in the Bosch video management system as well as trigger a Telex Radio Dispatch system to announce store or bank personnel’s two-way radios. This alerts security personnel that an issue is ongoing, so they can respond faster to help diffuse high-risk events. Other demonstrations include solutions for securing high-risk areas, capturing data for business intelligence, monitoring critical systems, including refrigerated cases and freezers in retail stores, and more. Technology training The new training and experience centre also includes a training facility, adding a central location for customers to attend technical training through the Bosch Academy. The Bosch team of trainers will provide customers with hands-on product education to enable integrators to install and run complex projects more efficiently and profitably. Open for visitors System integrators, end-users, consultants, and other industry professionals interested in a private demonstration session at the new Bosch Training and Experience Centre in Bentonville, Arkansas, can contact their local Bosch sales representative to schedule a visit.

‘We want to become better known for access control’ - Q&A with Bosch Building Technologies’ Gregor Schlechtriem
‘We want to become better known for access control’ - Q&A with Bosch Building Technologies’ Gregor Schlechtriem

Gregor Schlechtriem has worked in the access control market for over 20 years and is now responsible for the Access & Intrusion Business Unit at Bosch Building Technologies. In this interview, the expert talks about key industry trends, the impact of the COVID-19 (Coronavirus) pandemic, technical innovations and his company’s strategy. Mr. Schlechtriem, you have many years of experience in the security technology market. What is your background and what are your responsibilities as Senior Vice President at Bosch Building Technologies? Gregor Schlechtriem: I am a trained engineer and electrical technician, and have been involved with access control in the broadest sense, since I started my career in the late 1980s. I started in the field of parking garage technology and then switched to security technology in 2001, as Managing Director of micos GmbH, which specialised in traditional access control. micos GmbH was known for its highly available and highly secure access control systems, for critical infrastructure and government applications. Many systems from that time are still in use today and continue to be supported and upgraded. Bosch is continuing micos’ business here? Gregor Schlechtriem: Exactly, micos was taken over in 2004 by Bosch Security Systems, now known as Bosch Building Technologies. Since then, we have continuously been developing the access control business. Being part of the Bosch Building Technologies division, we benefit a lot from international cooperation with colleagues Being part of the Bosch Building Technologies division, we benefit a lot from international cooperation with colleagues and from overlap with other product lines, such as intrusion detection technology and video security. This gives us the opportunity to implement outstanding project solutions for demanding customers in an international environment. In developing this business, I rely on my experience from other interesting roles at Bosch that I took on, after micos was bought in 2004. For a time, I worked in the European System Integrator Business, which I also had the privilege of managing for several years, as well as being directly responsible for business units. In Fairport, USA, I had the overall responsibility for intrusion detection technology for many years, as I later did in Eindhoven for video systems. Since 2018, the global access control and intrusion detection business has once again been my direct responsibility. At Bosch Building Technologies, we have in the meantime assigned sales to the respective business units, so that we can develop our product and solution portfolio, in close cooperation with sales and our regular customers. Our main task now is to make our access control portfolio accessible to a broader market. We want to make Bosch much better known, as an access control provider, in the international market. After all, with our own access product portfolio, the power of the Bosch Group and over 40 years of experience in this sector, we have a lot to offer. As an expert in access control, how do you see the industry developing? In which direction is it currently evolving? Gregor Schlechtriem: First of all, I see that security requirements are constantly increasing. Whereas there are currently still simple ‘key replacement systems’ that merely record card numbers, such an approach, to a large extent, no longer meets today’s security and user experience requirements.The core task of access control has not changed over the years In the beginning, access control was more or less a kind of key replacement. Later, there was the possibility of increasing security via a pin code, i.e., via verification through simple data inputs. The next step in this direction was biometrics, which is another key step up, because it allows verification by means of unmistakable characteristics. However, the core task of access control has not changed over all the years and has basically always remained the same: access control means determining who has an access request and checking whether this request can be fulfilled. What’s next on this path to greater security? Gregor Schlechtriem: Biometrics-based access control is becoming increasingly powerful and user-friendly through the use of artificial intelligence (AI). Here, data protection plays a major role, as wherever identities are established and movement data is recorded, it is necessary to reconcile the evolving technology with data protection.Biometrics-based access control is becoming increasingly powerful and user-friendly through the use of artificial intelligence The question of data protection is becoming even more significant, as systems increasingly migrate to the Cloud. Bosch puts particular emphasis on ensuring that, even in the cloud, the data generated in access control is always in line with data protection rules, regardless of where it is located. In my opinion, this trend towards the Cloud will continue, because companies are increasingly looking for complete service offerings, so that they can focus on their core business. Also, a system in the Cloud is easier to maintain and always up-to-date with the latest software, which makes cloud solutions even more attractive for providers and users. How can higher security be reconciled with a good user experience? Gregor Schlechtriem: Today, the card still plays a central role in the user experience, as the essential credential. Another current trend is ‘one card for everything’: with the increasing availability of secure multi-function smart cards, the possibility arises to use cards beyond the pure access function, for example, for payment in the canteen, at the catering and coffee machines, and in the parking garage, as well as simple access to other properties and so on.The security of cards has evolved significantly and kept pace with requirements The security of the cards, the reading and encryption processes, has evolved significantly and kept pace with requirements, although we are also facing an installed base that no longer meets these requirements, due to outdated systems. Today, it is standard for communications between reader and card to be encrypted. In some cases, the keys are also only held centrally to further increase security. The security systems industry was also affected by the COVID-19 (Coronavirus) pandemic. How do you think the industry has changed? What technical solutions have emerged during this time? Gregor Schlechtriem: First of all, there is a certain need for retrofitting in the industry due to changes in how buildings are used. For example, American retailers used to be open around the clock and always had staff on site. Now, due to COVID-19, stores are also closed, and this results in a whole new need for intrusion detection and access control systems to protect the buildings. For access control, an obvious task has arisen as a result of the COVID-19 pandemic, namely to track contacts, as far as this is compatible with data protection. We actually expected more to happen here, but in our observation, many companies did quite little, despite clear and simple steps that could have been implemented relatively quickly. The installed access control systems clearly lag behind the technical possibilities. Another topic that the COVID-19 pandemic has brought into focus is hygiene Another topic that the COVID-19 pandemic has brought into focus is hygiene. Companies should actually have invested in contactless systems here and retrofitted speed gates or motorised doors. But in many cases this was not put into practice. The door opener is still often used, which has to be operated manually and therefore, is touched multiple times. But, if everyone presses the same button, that doesn't help hygiene. Surprisingly, this is different in North America. Here, ‘request-to-exit’ proximity detectors are used almost everywhere, which avoids this problem completely and releases the door, when an authorised person approaches it. Mobile access and smartphone-based access control are also growing markets. What kind of developments do you see in these areas? Gregor Schlechtriem: I already mentioned that users increasingly want to be able to use one card for several applications. But, what we are seeing here is that even with the most modern cards, which have a lot of applications loaded on them, we are reaching performance limits and the user experience suffers. If you compare the card with the smartphone as a credential, you have a much more attractive integration platform there, which is significantly faster and delivers much better performance. For us, the mobile credential or the smartphone is the future, because it simply offers more possibilities that the card will not be able to provide in the long term. What is the specific direction Bosch is taking here? Gregor Schlechtriem: We are currently working on a broad implementation. A whole team is working on the user experience around the smartphone, because it’s understood that smartphone-based access has to work just as easily, as it currently does with a card.A whole team is working on the user experience around the smartphone In theory it does, but if you look at some of the actual implementations, this topic is still relatively complex. In terms of user experience and automation, we still have quite a way to go, and we are working hard on that at the moment. The user experience is one side of the coin, the other side concerns establishing security in the smartphone as a whole. In other words: How do I make the smartphone secure enough as a mobile credential, to meet my access control requirements? We are also working intensively on this. That's actually an IT task. Do you do this yourself at Bosch or do you work with external experts here? Gregor Schlechtriem: We have our own powerful Bosch IT, which also manages our company smartphones. If our company smartphones are lost, the data on them is automatically deleted. The devices use biometrics to identify users, before they can access the data. It is a sound security concept that a card cannot offer. Moreover, we are working with other partners in the IDunion project, to create the additional infrastructure around mobile credentials as well. What exactly is the IDunion and what role does Bosch play? Gregor Schlechtriem: Digital identities must be openly accessible, widely usable, interoperable, and secure. This applies not only to access control, but to the digitised economy in general. The IDunion project has set itself the task of creating the infrastructure for this, in the form of an independent wallet, i.e., secure identity storage on smart devices. The project is funded by the German Federal Ministry for Economic Affairs and Energy (BMWI), because digitisation is also a critical social issue. We are intensively involved in the ‘Physical access to the building’ work package in this consortium. Through this involvement, we want to ensure that our access control systems benefit from this infrastructure and are open to future digital business models. Does ‘digital identity management’, which includes biometrics and mobile access, also play a role for Bosch? Yes, it plays an important role for us, and I wouldn’t consider these topics separate Gregor Schlechtriem: Yes, it plays an important role for us, and I wouldn’t consider these topics separate. For me, a mobile device has the advantage that it has already ensured and verified my identity from the moment of interaction. That’s the fascinating thing about it. If I only allow the device to communicate with the access control system, if I have identified myself first, I have implemented biometrics and access control together in a widely accepted process. From my point of view, this is a very interesting perspective, in terms of security and user experience, because the biometrics procedures in smartphones are, I think, the best currently available. In my view, the smartphone has the potential to take over central functions in access control in the future. What are your goals for the access control business of Bosch Building Technologies in the near future? Gregor Schlechtriem: We will continue to focus on specific solutions for large customers. That is the continuation of our current strategy. In these projects, we will introduce new topics as I have just described, i.e., primarily new technology elements. I believe that, precisely because of the longevity of access control, a long-term migration capability is also of particular importance. We want to reach out to the broader market and make more widely available, what we have developed in terms of technology and innovation. We are currently in the process of setting up and optimising our sales organisation, so that it becomes much more widely known that we at Bosch have our own powerful access control portfolio, which can be used for all kinds of applications. In addition, we want to differentiate ourselves in the market with our systems, in line with the motto of our founder, Robert Bosch: ‘Technology for life’. The user experience with Mobile Access should be simple, straightforward, and secure: You hold your smartphone in front of the reader and the door opens.
