Though it has been statistically proven that taking a plane is no riskier than taking a bus, people do have reasons to put extra caution on air travel safety, especially in a time replete with terrorist threats.

A major line of defence must be the various sections of the airports, which, as a gateway to the outside world and transportation hub of the city, has always been on the top of the safety list of the government and all related authorities. Dahua’s Airport Solution is an intelligent security system to help ensure the safety of the airports.

Elements of an effective solution

First of all, an effective solution requires a complicated collaboration of multiple (sub)systems such as monitoring system, alarm system, access control system, network transmission system and management platform. As is known to all, the more steps and players it takes, the higher likelihood for a mistake to occur.

Secondly, airports include a variety of places such as terminal areas, parking lots, office areas, freight areas, front desk areas (including the square in front of the terminal building), the flight areas, hangars, the perimeter area and so on, each of which operate on vertical management system. Yet due to the diversity of places and the complexity of personnel & cargoes coming in and going out in huge flow, there are too many risky elements to control.

Thirdly, it’s not only about accuracy but also about swiftness when it comes to airport security. Safety should bring efficiency and not the other way around. For example, in April 2017, a drone flew into Chengdu Airport, resulting in the runway closing down for 80 minutes, the loss of which was estimated as at least 10 million dollars, not to mention collateral damages in the broad sense.

Unifying a security system

Designed to solve all the difficulties mentioned above, Dahua’s Airport Solution is a unified security system combining multifunctional HD surveillance cameras with deep-learning AI that can analyse the big data to get the target, be it a car, a face or a series of numbers.

In terms of vehicle management: you can adopt all-in-one cameras to capture and recognise license plates of vehicles accessing the airport. This will trigger the alarm when detecting illegal, stolen, blacklisted, hit-and-run, crime-related and other suspects’ vehicles.

Covering the whole route of a vehicle, from entrance highway, to parking lots and then to exit, the surveillance system can effectively assist security guards and police to keep a smooth service, and respond quickly when things go wrong, even if it’s just something from the car that was left behind due to carelessness.

In terms of passenger management, the same full coverage of the security system also applies to this, from someone stepping off the car to one’s entering terminal building and checking-in area and all the way to the last step to the boarding gate. The HD surveillance cameras endowed with deep-learning AI have world-leading accuracy in face recognition and e-passport verification. Any suspect, should they show up in the airport area, will at once trigger the alarm.

Guarding the airport perimeter

Dahua’s Airport Solution also takes care of another crucial part of airport that is the perimeter area. One must resort to special equipment like thermal imaging cameras to keep the safety of the said area. An example of this is Dahua’s solution for one specific airport, which covers a perimeter of 30 km and boasts an annual throughput of 30,000,000 people and 8,000,00 tons of cargo.

According to the thermal imaging calculation form below:

Dahua chose to use a 100mm lens with a resolution of 640 x 512 and set the installation height at 5M, which detects 1.8m x 0.5m

Dahua chose to use a 100mm lens with a resolution of 640 x 512 and set the installation height at 5M, which detects 1.8m x 0.5m, showing people from within 3000m. The perimeter will be well covered for intruder detection purpose with 10 cameras.

The intelligent analysis of IVS (intelligent video system) requires 10 x 10 pixels, under which condition, each thermal imaging camera can detect and analyse objects from within 400m. There is in total 12km of perimeter length in need of such cameras, so Dahua chose to place 30 there, totalling 40 thermal imaging cameras to solve the problem.

Advantages of using Dahua tech

It should be noted that Dahua’s thermal imaging technology has the following advantages: PTZ function, long distance surveillance (which can detect a vehicle 8.8 km away), long distance zoom, binocular lens (optical and thermal imaging lens), and strong intelligence (which can detect intrusion). Compared to alternate perimeter protection equipment on the market today, such as vibration fibre sensor and IR beam sensor, thermal imaging camera has higher accuracy and less false alarm while directly providing video to verify.

Dahua has established stable cooperation with world-renowned platforms like Genetec, Milestone, Avigilon, AXXON, ISS, infusing Dahua’s Airport Solution with more possibilities. Supported by strong R&D resources and good working relationships earned in multiple previous collaborations with partners, Dahua can ensure seamless integration whether it’s front-end IPC or back-end NVR, fulfilling different demands of clients and building a sound security system for the airport.

In future, Dahua will keep investing in R&D of cutting-edge technologies into the realm of civil aviation video surveillance solutions. With a mission of “Safer Society, Smarter Living”, Dahua will continue to focus on “Innovation, Quality, and Service” to serve partners and customers around the world.

Virtual worlds disrupt building security & facility management
Virtual worlds disrupt building security & facility management

From satellite imagery to street views to indoor mapping, technology has disrupted our past world. This has left us dependent upon new ways to visualise large spaces. This new world has brought many benefits and risks. But what does that mean for the security professional or facility manager today and what technologies can be used to secure buildings and improve facility operations? A brief history of 3D technology Starting May 5, 2007 (inception 2001), Google rolled out Google Street View to augment Google Maps and Google Earth; documenting some of the most remote places on earth using a mix of sensors (Lidar/GSP/Radar/Imagery). The mission to map the world moved indoors May 2011 with Google Business Photos mapping indoor spaces with low cost 360° cameras under the Trusted Photographer program. In the earlier days, 3D scanning required a high level of specialisation, expensive hardware and unavailable computing power With the growth of 3D laser scanning from 2007 onwards, the professional world embraced scanning as effective method to create digitised building information modelling (BIM), growing fast since 2007. BIM from scanning brought tremendous control, time and cost savings through the design and construction process, where As-Built documentation offered an incredible way to manage large existing facilities while reducing costly site visits. In the earlier days, 3D scanning required a high level of specialisation, expensive hardware, unavailable computing power and knowledge of architectural software. Innovation during the past 8 year, have driven ease of use and lower pricing to encourage market adoption. Major investments in UAVs in 2014 and the commercial emergence of 360° photography began a new wave of adoption. While 3D scanners still range from $20K – $100K USD, UAVs can be purchased for under $1K USD and 360° cameras for as low as $100. UAVs and 360° cameras also offer a way to document large spaces in a fraction of the time of terrestrial laser scanners with very little technical knowledge.  Access to building plans, satellite imagery, Google Street View, indoor virtual tours and aerial drone reconnaissance prove effective tools to bad actors The result over the past 10+ years of technology advancement has been a faster, lower cost, more accessible way to create virtual spaces. However, the technology advances carry a major risk of misuse by bad actors at the same time. What was once reserved to military personal is now available publicly. Access to building plans, satellite imagery, Google Street View, indoor virtual tours and aerial drone reconnaissance prove effective tools to bad actors. Al Qaeda terror threats using Google Maps, 2007 UK troops hit by terrorists in Basra, 2008 Mumbai India attacks, 2016 Pakistan Pathankot airbase attacks, ISIS attacks in Syria using UAVs, well-planned US school shootings and high casualty attacks show evidence that bad actors frequently leverage these mapping technologies to plan their attacks. The weaponization of UAVs is of particular concern to the Department of Homeland Security: "We continue to face one of the most challenging threat environments since 9/11, as foreign terrorist organisations exploit the internet to inspire, enable or direct individuals already here in the homeland to commit terrorist acts."   Example comparison of reality capture on the left of BIM on the right. A $250 USD 360° camera was used for the capture in VisualPlan.net software What does this mean for the security or facility manager today? An often overlooked, but critical vulnerability to security and facility managers is relying on inaccurate drawing. Most facilities managers today work with outdated 2D plan diagrams or old blueprints which are difficult to update and share.Critical vulnerability to security and facility managers is relying on inaccurate drawing Renovations, design changes and office layout changes leave facility managers with the wrong information, and even worse is that the wrong information is shared with outside consultants who plan major projects around outdated or wrong plans. This leads to costly mistakes and increased timelines on facility projects.  Example benefits of BIM There could be evidence of a suspect water value leak which using BIM could be located and then identified in the model without physical inspection; listing a part number, model, size and manufacture. Identification of vulnerabilities can dramatically help during a building emergency. First Responders rely on facilities managers to keep them updated on building plans and they must have immediate access to important building information in the event of a critical incident. Exits and entrances, suppression equipment, access control, ventilation systems, gas and explosives, hazmat, water systems, survival equipment and many other details must be at their fingertips. In an emergency situation this can be a matter of life or death. Example benefit of reality capture First Responders rely on facilities managers to keep them updated on building plans A simple 360° walk-through can help first responders with incident preparedness if shared by the facility manager. Police, fire and EMS can visually walk the building, locating all critical features they will need knowledge of in an emergency without ever visiting the building. You don’t require construction accuracy for this type of visual sharing. This is a solution and service we offer as a company today. Reality capture is rapidly becoming the benchmark for facility documentation and the basis from which a security plan can be built. Given the appropriate software, plans can be easily updated and shared.  They can be used for design and implementation of equipment, training of personnel and virtual audits of systems or security assessments by outside professionals. Our brains process visual information thousands of times faster than text. Not only that, we are much more likely to remember it once we do see it. Reality capture can help reduce the need for physical inspections, walk-throughs and vendor site-visits but more importantly, it provides a way to visually communicate far more effectively and accurately than before. But be careful with this information. You must prevent critical information falling into the hands of bad actors. You must watch out for bad actors attempting to use reality capture as a threat, especially photo/video/drones or digital information and plans that are posted publicly. Have a security protocol to prevent and confront individuals taking photos or video on property or flying suspect drones near your facility and report to the authorities. Require authorisation before capturing building information and understand what the information will be used for and by who.There are a number of technologies to combat nefarious use of UAVs today Nefarious use of UAVs There are a number of technologies to combat nefarious use of UAVs today, such as radio frequency blockers and jammers, drone guns to down UAVs, detection or monitoring systems. Other biometrics technologies like facial recognition are being employed to counter the risk from UAVs by targeting the potential operators. UAVs are being used to spy and monitor for corporate espionage and stealing intellectual property. They are also used for monitoring security patrols for the purpose of burglary. UAVs have been used for transport and delivery of dangerous goods, delivering weapons and contraband and have the ability to be weaponised to carry a payload.Investigating reality capture to help with accurate planning and visualisation of facilities is well worth the time The Federal Aviation Administration has prevented UAV flights over large event stadiums, prisons and coast guard bases based on the risks they could potentially pose, but waivers do exist. Be aware that it is illegal today to use most of these technologies and downing a UAV, if you are not Department of Justice or Homeland Security, could carry hefty penalties. Facility managers must have a way to survey and monitor their buildings for threats and report suspicious UAV behaviours immediately to authorities. At the same time, it’s critical to identify various potential risks to your wider team to ensure awareness and reporting is handled effectively. Having a procedure on how identify and report is important. Investigating reality capture to help with accurate planning and visualisation of facilities is well worth the time. It can help better secure your facilities while increasing efficiencies of building operations. Reality capture can also help collaboration with first responders and outside professionals without ever having to step a foot in the door. But secure your data and have a plan for bad actors who will try to use the same technologies for nefarious goals.

Intellectual honesty: the growth of Cobalt Robotics and robots in security
Intellectual honesty: the growth of Cobalt Robotics and robots in security

The best route to greater adoption of robotics in the field of physical security is intellectual honesty, says Travis Deyle, CEO and co-founder of Cobalt Robotics. “Robots are not a panacea, so we must be clear and honest about capabilities and use cases,” he says. “If you are dishonest, people will lose faith. We must have clear expectations about what’s feasible today and possible tomorrow.” The robotics tide is turning in the security market, which is notoriously slow to embrace new technologies. “The tone has changed at recent security events,” says Deyle. “Previously, robots were thought of as a science experiment. But now, there are big-name users wanting to discuss proof of concept. It has evolved from being a novelty to now it’s time to give it a serious look. They want us to help them sell the concept up the chain of command. It’s helpful to have conversations with other parts of the company because it has an impact on the culture of the company.” The robotics tide is turning in the security market, which is notoriously slow to embrace new technologies Cobalt’s robots are purpose-built for a specific use case: providing after-hours support and security for corporate locations. Indoor environments, confined and controlled, present fewer navigation challenges for robots, which can quickly become familiar with the surroundings and navigate easily through an office space. Indoor robots can provide benefits beyond security, too, such as facility management, promoting employee health and safety, and emergency response. Cobalt's human-centred design Cobalt’s robots also interact well with people. They are friendly and approachable and make employees feel safe and secure. The human-centered design promotes that interaction, and a real person (located remotely) can enter into any interaction instantly as needed. “We combine machines with people,” says Deyle. “We allow the machine to do what it does best, such as dull and boring activities, and add the flexibility and cultural relevancy of having a person there.” Cobalt’s robots also interact well with people, they are friendly and approachable and make employees feel safe and secure When a robot is deployed, it performs a brief mapping phase (about an hour), in which it moves around and builds up a “map” of its space and develops its patrol route. Over time, it lingers more in areas where it encounters more incidents. There are 60 sensors on the robot, including day/night cameras, high-resolution thermal cameras, a card reader that integrates with the corporate access control system, a microphone, and environmental sensors for temperature and humidity.  The robot builds models of what’s normal in its environment in terms of people, sound, motion, open doors and windows, and even leaks and spills. And then it detects anomalies and sends relevant notifications to Cobalt specialists, who respond and manage any events in real time. The machine provides unwavering attention, perfect recall, and accountability. Cobalt robots have been designed to help bridge the problems faced with utilising guards and cameras  Accomodating various anomalies  The Cobalt robot is designed to blend into a high-end office environment, with flexible fabric and a corporate design aesthetic. It is stable beyond 45-degrees, so it’s hard to topple over. The 5-foot-2-inch robot can see over desks and cubicles. It is designed to bridge the gap between guards, who are expensive and underutilised during uneventful night shifts, and cameras, which are unable to respond to nuanced situations. Cobalt Robotics already has customers in defense, finance and manufacturing, and a handful of Fortune 500 companies are looking at the service Autonomous navigation uses artificial intelligence (AI) and machine learning to avoid static and dynamic obstacles. Over time, the robot accommodates various anomalies such as loud machinery noise, and “semantic mapping” adds intelligence to its map. When the robot figures out that a picture on the wall is not a real person, for example, it stores that information for future reference.  The technologies enabling robotics in the indoor environment are mature – there have been variations of security robots in operation for decades. What has changed is the costs of the technologies, which are now inexpensive enough to make a robot affordable to businesses. Cobalt Robotics offers an all-inclusive service providing hardware, software, service and maintenance as well as the remote human interface. All together, the service is a third to half the cost of a man-guard, and it bills monthly, says Deyle. Cobalt Robotics offers an all-inclusive service providing hardware, software, service and maintenance as well as the remote human interface Cobalt Robotics already has customers in defense, finance and manufacturing, and a handful of Fortune 500 companies are looking at the service. They are currently operational in the San Francisco Bay area and Chicago and will be in six other geographies in the next three months (in response to customer needs). Uses include offices, museums, warehouses, technology centres, and innovation centres.  A former Google employee, Deyle’s experience in robotics goes back to his Ph.D. studies at Georgia Tech, where he worked on developing a robot to deliver healthcare to homebound patients. Deyle and Cobalt Robotics co-founder Erik Schluntz departed Google in 2016 to form Cobalt Robotics. In just 12 months, Cobalt went from the initial idea to paid robot deployments.

Which segments are under-served in the physical security industry?
Which segments are under-served in the physical security industry?

Physical security technologies operate successfully in many different markets, but in which markets do they fall short? Physical security is a difficult challenge that can sometime defy the best efforts of manufacturers, integrators and end users. This is especially the case in some of the more problematic markets and applications where even the best technology has to offer may not be good enough, or could it be that the best technology has not been adequately applied? We asked this week’s Expert Panel Roundtable to reflect on instances when the industry may fall short: Which segments of the physical security industry are most under-served and why?
