The user may know that fixed licence plate reader technology (LPR) is one of the most powerful security tools available for protecting buildings and perimeters of geographical areas. Best practices for ELSAG® Fixed Plate Hunter LPR systems include:

  • College, university, and school campuses
  • Airports
  • Casinos
  • Manufacturing facilities
  • Houses of worship
  • Transportation depots
  • Utility infrastructure
  • Municipal buildings
  • Military campuses
  • Ports and border stations

Fixed plate readers are also proving to be fundamental components of public safety missions designed to protect people in high-pedestrian areas, or those targeted by traffickers and predators. This case study offers three real-life instances of fixed or semi-fixed deployments that not only keep buildings and perimeters secure, but also people.

Identifying suspect vehicle

The ELSAG Fixed Plate Hunter ALPR in action fixed ELSAG ALPR cameras are attached to infrastructure like a utility pole or sign gantry.

  • Fixed cameras scan plates of passing vehicles, capturing licence plate numbers, date/time stamps and GPS locations.
  • The infrared camera captures b/w images of each plate and a colour camera captures overview images of each vehicle.
  • A computer reads the plate characters and compares them with a hot list.
  • Plates that match a white or hot list trigger instant alerts to security officials.

ELSAG Fixed Plate Hunter ALPR Performance:

  • Cameras read licence plates, day or night, in any weather.
  • Plates are processed at up to 150 mph (241 kph) passing speeds, from over 100 feet away.
  • Plates are recognised using specially designed protocols for each jurisdiction in which the systems are deployed ELSAG Fixed Plate Hunter ALPR Performance.
  • Alerts are sent to officials, command centres and other patrol cars instantaneously, upon identifying a suspect vehicle.
  • Captured data includes date/time stamps, GPS coordinates and photo of the licence plate.
  • Fixed systems can capture the speed of passing vehicles.
  • Hot list updates are wirelessly received and transmitted.

Keeping people safer

Duck, NC is a coastal community located in Dare County on the Outer Banks of North Carolina

There are flexible LPR technologies available that allows the user to address any law enforcement and security mission or challenge that involves vehicles with licence plates. Here are three examples of LPR programs using Leonardo systems that were started for routine purposes, then expanded to help keep people safer and more secure.

Duck, NC is a coastal community located in Dare County on the Outer Banks of North Carolina. It hosts about 20,000 people during the summer months. In 2015 The Chief of Police began an LPR program with two fixed cameras to help manage ‘burglary season’ on the island. Cameras read plates as vehicles enter and leave town. Almost immediately two arrests were made in separate cases of burglars who had been stealing from area homes for over a decade.

Identifying stolen vehicles

The Duck, NC program also identified stolen vehicles, located missing persons, and exposed narcotic activities, leading to the expansion of their LPR network. Additional fixed cameras protect the 30 miles from Manns Harbor to the Wright Memorial Bridge.

The Dare County LPR program is now instrumental in keeping track of residents who adhere to hurricane evacuations and any who choose to stay on the island. LPR traffic tallies and licence plate numbers give officials an estimate of people who may need help during the crisis, and an address. “Our LPR systems provided us a starting point to begin and end any type of situation or investigation.” John Cueto, Retired Chief of Police, Duck, NC.

Pedestrian-heavy area

In 2015, BA Tránsito, the road traffic authority in Buenos Aires, used a network of fixed LPR cameras to support an initiative designed to protect the pedestrian-heavy area of the oldest part of the capital city known as the Autonomous City of Buenos Aires.

Only taxi cabs, government officials and other select vehicles are allowed to use the streets there. If any LPR camera reads the licence plate of a vehicle without a permit, they are mailed a ticket. The success of the original LPR program led to a 2017 expansion to relieve traffic congestion in the area immediately surrounding the Autonomous City. This busy metropolitan area, the ‘centre city ring,’ has multi-lane roads in several directions, dangerously busy with vehicle activity.

Cutting down daily traffic

To encourage compliance, every licence plate number read is prominently displayed on digital signs

BA Tránsito cut down daily traffic by half using fixed LPR systems. Licence plates ending with odd numbers can enter the centre city ring on Mondays, Wednesdays, and Fridays. Plates ending with even numbers have access on Tuesdays, Thursdays and Fridays. Police wait nearby to stop unauthorised vehicles. To encourage compliance, every licence plate number read is prominently displayed on digital signs for all other drivers to see.

The NTSCIU covers eight counties, looking for criminals who use interstates and highways to smuggle illicit contraband. In 2017 they started an LPR program with two mobile LPR units to read plates as officers patrolled. They expanded their LPR network in 2018 with the addition of a LPR radar trailer housing two fixed cameras to serve as a semi-fixed system that could be easily moved to different places along highways, as needed.

LPR radar trailers

In 2018, they purchased an additional trailer to use along strategic routes and support requests from other agencies within the NTSCIU to help curtail crimes such as burglaries. While there are countless headlines about NTSCIU’s removal of illicit drugs from Texas highways and seizures of drug money and other contraband, aided by LPR technology, one of their most important cases was the recovery of a child abducted in California.

As described by an NTSCIU supervisor, that case alone paid for their entire investment in LPR technology

As described by an NTSCIU supervisor, that case alone paid for their entire investment in LPR technology. In 2018, the NTSCIU learned of an Outlaw Motorcycle Gang rally in their jurisdiction. They deployed LPR radar trailers around the event site to gather data (licence plate number, photos of each plate on a bike or vehicle, date and time stamps, and trailer identifier).

Fixed LPR technology

Should events occur during the rally that would require investigating, law enforcement could analyse the data for information to help resolve the issue. Agencies of every size will benefit from deploying fixed LPR technology—to aid security of places and people.

There are lease options and grants available to help with funding, and Leonardo even has a lower-cost video camera LPR solution available now. So, get your agency outfitted with this 21st-century technology that is changing law enforcement best practices by increasing capacity, productivity and facilitating creative ways to address any issue that involves a licence plate.

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
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.
