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.
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.
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.
Intelligent solutions, such as those derived from artificial intelligence, help critical infrastructure organisations make sense of vast amounts of data. These integrated applications, such as advanced video analytics and facial recognition, can automatically pinpoint potential breaches and significant events, and send alerts to the appropriate personnel, departments, and agencies. These solutions can be powerful in unifying disparate command centre technologies, fusing critical data input from emergency calls and responder activity to enhance situational awareness. Electrical substations are particularly vulnerable (and in need of extra security) due to their role in power distribution and the nature of their equipment. The challenge power utilities worldwide are facing is finding an affordable solution, which can help detect, deter and facilitate an informed response to a substation security event. Data capture form to appear here! U.S. regulations In the United States, this need is furthered by the physical security mandate CIP-014 issued by the North American Electric Reliability Corporation (NERC), calling for identification of security issues, vulnerability assessments and deployment of appropriate processes and systems to address. CIP-014 identification of security issues, vulnerability assessments and deployment of appropriate processes and systems to address CIP-104 specifically calls for implemented security plans that include measures to deter, detect, delay, assess, communicate, coordinate and respond to potential physical threats and vulnerabilities. Manufacturers of video and other systems are designing products to serve the critical infrastructure market. For example, Dahua Technology offers explosion-proof cameras with a combination of rugged reliability and superior optics that is a fit for surveillance of explosive and corrosive environments, including chemical plants, refineries, and other facilities in the oil and gas industry. This explosion-proof series of cameras are housed in enclosures that are certified to the ATEX and IECEx standards for equipment in explosive atmospheres. Each explosion-proof camera features Dahua’s Starlight technology for ultra low-light sensitivity and high-definition sensors that deliver clear images in real-time. They are IP68-rated to prevent water and dust ingress. Each explosion-proof camera features Dahua’s Starlight technology for ultra low-light sensitivity and high-definition sensors that deliver clear images in real-time Video footage in extreme temperatures Another manufacturer, Videotec, offers a range of cameras and housings that provide video footage regardless of aggressive external factors, such as ice cold, scorching heat, desert sand, the force of sea or wind, total darkness, pollution, corrosion and even explosive agents. SightSensor thermal systems enable a utility to detect and respond to substation security incidents across multiple sitesSightLogix smart thermal camera systems have been deployed to protect substations for electric utilities and other critical infrastructure facilities. SightSensor thermal systems enable a utility to detect and respond to substation security incidents across multiple sites, ranging from copper theft to vandalism while also meeting regulatory compliance. At each substation facility, Thermal SightSensors are positioned along the perimeter, and are paired with a high-resolution pan-tilt-zoom camera for alarm assessment. When a Thermal SightSensor detects an intruder, the target’s location information is sent over the network to a SightTracker PTZ controller, which automatically zooms and steers PTZ cameras to follow the intruder. The target’s location is also displayed on a topology site map to provide real-time situational awareness. Alarms are sent to the utility’s 24-hour security operations centre, which will contact law enforcement in real time when unauthorised intrusions are detected. Integrated intrusion detection and lighting systems The Senstar LM100 hybrid perimeter intrusion detection and intelligent lighting system is simplifying security at one U.S. electrical utility company. For years, the utility company had integrated its perimeter intrusion detection and lighting systems. The company has now installed the Senstar LM100 which provides detection and lighting in one product and saves them over $80,000 per site. The savings are a result of the reduction of electrical requirements, conduit, grounding, and associated labor, as well as the removal of certain equipment from project scope that are required for the two-system integration. The Senstar LM100’s perimeter LED-based lighting acts as an initial deterrent. If an intruder persists and an attempt to cut, climb or otherwise break through the fence is detected, the closest luminaire begins to strobe, and an alert is sent via a security management system. The intruder knows immediately they have been detected and that their exact location is known by security and others in the vicinity.
Videotec presents NTX, the new IP68 stainless steel thermal camera, developed to provide an efficient and preventative surveillance system in the most critical environmental conditions. The NTX thermal camera offers temperature detection based on the 4 central pixels of the image, and with the advanced version, the temperature of a specific object can be measured at any point in the image by means of defining a specific area. As well as this, the radiometric functions offer the option to set a temperature limit, beyond which an alarm will be raised. Unwanted intrusions These functions are necessary where fire prevention is required or in applications such as monitoring industrial processes or critical equipment, where the ability to identify something quickly and accurately, thus preventing problems or failures and keeping intervention times to a minimum, is essential. Configuring and controlling thermal image parameters is possible via the ONVIF Thermal Service Standard NTX can export all the data necessary for a centralised management of video feeds, data and alarms, and make it available to VMS via the ONVIF Profile S and Profile Q communication protocols. Also, configuring and controlling thermal image parameters is possible via the ONVIF Thermal Service Standard. NTX allows exploiting fully the features and the advantages offered by the thermal camera. This includes the ability to raise an alarm and initiate immediate actions in order to prevent accidents or unwanted intrusions into monitored areas. Adverse environmental conditions The NTX camera is made entirely from electropolished AISI316L stainless steel and stands out thanks to its compact design and light weight. This, and the fact that it can be connected quickly, makes installation and maintenance easier. The modular support for wall, ceiling or parapet is supplied as standard. The NTX has obtained Lloyd’s Register Marine Type Approval certification for the maritime and naval sector and complies with the standard for railway applications. NTX is exceptionally resistant to corrosion and has a wide operating temperature range (from -40°C to +65°C). Its IP66/IP67/IP68, NEMA Type 4X and Type 6P grades guarantee maximum protection and optimal camera operation in even the most adverse environmental conditions. The fact that the NTX is extremely sturdy and of high quality means it is ideal for the most demanding applications in the marine and industrial sectors, in critical infrastructures, power plants and transport sector, including railways and motorway tunnels.
