How AI and humans can work together is a longstanding debate. As society progresses technologically, there’s always the worry of robots taking over jobs.

Self-checkout tills, automated factory machines, and video analytics are all improving efficiency and productivity, but they can still work in tandem with humans, and in most cases, they need to. Video analytics in particular is one impressively intelligent piece of technology that security guards can utilise. How can video analytics help with certain security scenarios?

Video analytics tools

Before video analytics or even CCTV in general, if a child went missing in a shopping centre, we could only rely on humans. Take a crowded Saturday shopping centre, a complex one with a multitude of shops and eateries, you’d have to alert the security personnel, rely on a tannoy and search party, and hope for a lockdown to find a lost or kidnapped child. With video analytics, how would this scenario play out? It’s pretty mind-blowing.

As soon as security is alerted, they can work with the video analytics tools to instruct it precisely

With the same scenario, you now have the help of many different cameras, but then there’s the task of searching through all the CCTV resources and footage. That’s where complex search functions come in. As soon as security is alerted, they can work with the video analytics tools to instruct it precisely on what footage to narrow down, and there’s a lot of filters and functions to use.

Expected movement direction

For instance, they can tick a ‘human’ field, so the AI can track and filter out vehicles, objects etc., and then they can input height, clothing colours, time the child went missing, and last known location.

There’s a complex event to check too, under ‘child kidnap’. For a more accurate search, security guards can then add in a searching criterion by drawing the child’s expected movement direction using a visual query function. A unique function like this enables visual criteria-based searches rather than text-based ones. The tech will then narrow down to the images/videos showing the criteria they’ve inputted, showing the object/child that matches the data and filter input.

Detecting facial data

There are illegal demonstrations and troublesome interferences that police have to deal with

A white-list face recognition function is then used to track the child’s route which means the AI can detect facial data that has not been previously saved in the database, allowing it to track the route of a target entity, all in real time. Then, security guards can confirm the child’s route and current location. All up-to-date info can then be transferred to an onsite guard’s mobile phone for them to confirm the missing child’s movement route, face, and current location, helping to find them as quickly as possible.

Often, there are illegal demonstrations and troublesome interferences that police have to deal with. Video analytics and surveillance can not only capture these, but they can be used to predict when they may happen, providing a more efficient process in dealing with these types of situations and gathering resources.

Event processing functions

Picture a public square with a number of entries into the main area, and at each entry point or path, there is CCTV. Those in the control room can set two events for each camera: a grouping event and a path-passing event. These are pretty self-explanatory. A grouping event covers images of seeing people gathering in close proximity and a path-passing event will show when people are passing through or entering.

The video analytics tool can look out for large gatherings and increased footfall to alert security

By setting these two events, the video analytics tool can look out for large gatherings and increased footfall to alert security or whoever is monitoring to be cautious of protests, demonstrations or any commotion. Using complex event processing functions, over-detection of alarms can also be prevented, especially if there’s a busy day with many passing through.

Reducing false alarms

By combining the two events, that filters down the triggers for alarms for better accuracy to predict certain situations, like a demonstration. The AI can also be set to only trigger an alarm when the two events are happening simultaneously on all the cameras of each entry to reduce false alarms.

There are so many situations and events that video analytics can be programmed to monitor. You can tick fields to monitor any objects that have appeared, disappeared, or been abandoned. You can also check events like path-passing to monitor traffic, as well as loitering, fighting, grouping, a sudden scene change, smoke, flames, falling, unsafe crossing, traffic jams and car accidents etc.

Preventing unsafe situations

Complex events can include violations of one-way systems, blacklist-detected vehicles

Complex events can include violations of one-way systems, blacklist-detected vehicles, person and vehicle tracking, child kidnaps, waste collection, over-speed vehicles, and demonstration detections.

The use of video analytics expands our capabilities tremendously, working in real time to detect and help predict security-related situations. Together with security agents, guards and operatives, AI in CCTV means resources can be better prepared, and that the likelihood of preventing unsafe situations can be greatly improved.

It’s a winning team, as AI won’t always get it right but it’s there to be the advanced eyes we need to help keep businesses, premises and areas safer.

Crossing the divide - automating security processes across physical, business and IT domains
Crossing the divide - automating security processes across physical, business and IT domains

Security is a critical requirement for all organisations. Getting security right involves the correct mix of people, processes and technology working together. However, many enterprise companies don’t look at the full mix that encompasses information security, and instead split their physical security and business continuity teams away from their IT security departments. According to research by ASIS, around half (52 per cent) of companies have converged two or three out of their physical, IT security and business continuity teams together, with the majority of those opting to bring together their continuity and physical security teams. Of those that have not brought teams together, around 70 per cent have no plans to do so. It's Important to bring all department's security together The reason for this is that cybersecurity is perceived as having a more specialist role within the business and that this prevents companies from bringing their departments together. However, while IT security has its own specialist requirements and skills, it should not be looked at alone. Businesses are looking at how to manage risk more effectively across all their operations, and they have problems when their teams are siloed and don’t have the full picture. The Cybersecurity and Infrastructure Security Agency (CISA) has developed its own guide to this area, based on the growth of the Internet of Things and more connected devices entering both homes and businesses, so this will continue to grow in importance. The rise of automation The pace of change that companies face today, coupled with the impact of the COVID-19 pandemic, means that more organisations are moving to digital services and automating their operations as much as they can. Security is no exception here - according to our research on security and automation, 75 percent of companies say they would need an additional three or more analysts in place to deal with all their incoming alerts in the same day, while 83 percent say their teams face ‘alert fatigue.’ IT security teams are drowning in data, but they feel unable to cope - yet at the same time, they will have to work more closely with other departments as well. Automation is necessary to deal with all these problems, but it should not be looked at in isolation. While IT security teams are keen to invest in automation using technologies like Security Information and Event Management (SIEM) and Security Orchestration, Automation and Response (SOAR), these investments can be used across both physical and IT security. As IT security teams invest in automation, they can adapt and extend their approach to help risk management and security in the physical world as well. The best approach to be successful around this is to look at areas where real-world and IT security challenges cross over for businesses. To adopt this approach successfully involves understanding business processes better. Fraud detection processes Automation involves using data and analytics to improve how a process operates from beginning to end, including where IT and technology is used to support physical interactions or activities. A good example of this would be a bank’s fraud detection process, where multiple digital and physical transactions have to be monitored and investigated. Bringing together different teams - physical security, business continuity, risk management and IT security - is about how to protect the whole organisation against risk. While the most well-known area for fraud investigation would be credit card transactions, there are multiple different types of transactions to track, from national and international wire transfers to prepaid phone cards and other prepaid cards that can be used for credit purchases. Each of these will have its own workflows and requirements to investigate a transaction, This can include looking at whether transactions are false positives or need further investigation, which is based on a mix of digital documentation for online purchases and physical data from in-person transactions. At the same time, the sophisticated nature of fraud can mean there is a large IT component to any investigation. Members of the IT security team may need to be involved alongside the anti-fraud department. While this investigation is necessary, it pulls analysts away from cybersecurity tasks, which can be especially frustrating where false positives are concerned. Instead, automating the investigation process can help. Consolidating Physical, IT and risk management By consolidating processes and automating the workflow, this pulls physical, IT and risk management together in a smarter and more efficient manner. It also improves productivity for an anti-fraud team as they can remove false positives from the workflow and get automated support for IT analysis. If the team needs more human insight, they can bring this in where they need it rather than requiring it for every investigation. While anti-fraud is one example of where this kind of convergence and collaboration is required, there are other use cases. For instance, industrial control and manufacturing applications that run production lines around the clock are frequently targeted for attacks, either to steal vital data or to disrupt business operations. This crosses over from the realm of IT into the world of operational technology, where systems are very different and the systems used may have been in place for years, even decades. Bringing together different teams - physical security, business continuity, risk management and IT security - is about how to protect the whole organisation against risk. By working together, teams can be more efficient rather than working in their respective silos. This involves better use of data across those teams, which will rely on more automation to be efficient. Using SOAR, security analysts and business risk professionals can cut the amount of time needed to respond to potential problems, reducing the impact and remediating faster. At the same time, it reduces the waste associated with false positives and manual work. The emphasis here should be on how to support the business with better security - by consolidating processes and working more effectively, security teams across the organisation can achieve that goal.

Everbridge Control Center deployed by G4S to accelerate Abu Dhabi Global Market Square’s physical security digital transformation

The Abu Dhabi Global Market Square (ADGMS), located on Al Maryah Island, in the United Arab Emirates capital, Abu Dhabi, is a high-profile, architecturally compelling business and hospitality hub. Many of the most globally prestigious companies inhabit the buildings, in the award-winning financial centre. Abu Dhabi Global Market Square ADGMS also hosts frequent international dignitaries and large-scale public events, including the Abu Dhabi national New Year’s fireworks display. Abu Dhabi Global Market Square was the first project in the UAE, to achieve LEED Core and Shell (LEED-CS) Gold pre-certification, by the US Green Building Council (USGBC). The Abu Dhabi Global Market Square (ADGMS) consists of: 450,000 sq. m of office space, a lavish retail section and luxury business hotel offerings, 4 Grade-A commercial office towers with 30 floors each, 4 km waterfront promenade, Over 2,000 cameras, and Over 1,000 doors. Unconnected security systems and situational awareness gaps Because of its iconic status, the Abu Dhabi Global Market Square faces many unique challenges to security, including: Political pressure - Because of ADGMS’s status and frequent high-profile international visitors, any disruption to operations - be it natural disaster, activism, terror or other critical events, could cause issues on a national scale. Protection for VIPs - Regular visits from prestigious VIPs, such as sheikhs, the royal family, and global business leaders, elevates security risks and the need for executive protection. Unobtrusive security - ADGMS is a public space with tenanted offices, meaning that security must be robust, but unobtrusive and follow all global data, and privacy regulations. Physical location - Being situated on an island is an extra security risk, complicating the ability to enter and exit the space, during planned and unplanned critical events or emergencies. Architecture - The buildings in ADGMS are mostly glass, with many levels, making it difficult to secure. Previously, a number of systems were deployed to help with security and life safety, such as CCTV, access control, fire detection, and building management. However, these were not connected and left gaps in situational awareness, which ADGMS found unacceptable. In light of the above challenges, ADGMS building managers felt it essential to harden security, across the market square, within these buildings and in connecting areas. Risk intelligence & integrated control of physical assets Martin Grigg, Principal Consultant and Project Lead for PTS Middle East was selected to design and oversee the project Abu Dhabi Global Market Square approached PTS Middle East (PTS Consulting Group Ltd.), a multi-national security and digital transformation consultancy, which carried out the threat, risk and vulnerability assessment, designed the mitigation measures, and provided oversight of the installation and commissioning of the entire system. They were also tasked with ensuring that the system met the operational requirements and was fit for purpose, and proportional to the risks, faced by ADGMS. Martin Grigg, Principal Consultant and Project Lead for PTS Middle East was selected to design and oversee the project, right from concept to completion. Everbridge Control Center deployed Following the assessment, G4S, a British multi-national risk consultancy company, headquartered in the United Kingdom, was selected to deliver the project, based on its experience in helping secure many of the region’s most prestigious locations. G4S is also a global partner with Everbridge, and together, they have secured people, assets and infrastructure for numerous organisations. G4S selected Everbridge Control Center to integrate and manage all the technology, which is coming into their Security Command Centre (SCC). Everbridge Risk Center was also deployed to provide real-time threat intelligence to ADGMS. Critical issues solved by Everbridge technology: Consolidation of four control rooms into one, reducing the office space needed for security - This premium space is now free and able to be re-purposed as rentable office space, Reduction of man guarding costs, as fewer resources are needed to secure the facility, Real-time situational awareness allows for reduced risk, accelerated response times and keeps stakeholders informed, Everbridge Control Center provides event driven, unified interface and automated SOP presentation, Everbridge technology provides flexibility to adapt, as requirements change, Reduction in time taken to identify a security incident and resolve it, Intelligence from the facial recognition systems is proactively used to welcome friends and identify known criminals, Risk intelligence to identify events, such as sandstorms, allows ADGMS to act faster, enabling them to reduce the risk to people and operations, and Automated reporting capabilities save huge amounts of time and resources - A report that took 20 minutes can now be automated in seconds.
