Perimeter security has evolved in recent years from an emphasis on fences and low-cost sensors to a broader systems approach that incorporates a variety of technologies. Protech is among the companies leading the transition and positioning itself as a one-stop systems provider at the perimeter.

Mergers and acquisitions

In 2014, U.S.-based Protech merged with Sorhea, a French manufacturer of perimeter security systems. The combination expanded Protech’s business from one product to the ability to supply an entire system. Parent company Groupe ST also owns TIL Technologies, which designs, manufactures and markets electronic access control, intrusion detection and video systems. Sorhea is strong in Europe, the Middle East and Africa, and Protech’s plan is to further expand its presence and range of systems in the United States in the next year and a half, while building a network of well-trained integrators.

Just this year, Groupe ST also acquired VideoWave Networks, a developer of video analytics systems that detect and track objects in outdoor environments – adding another new element to the portfolio, and the ability to supply systems with even more capabilities. Sorhea/Protech CEO Eric Thord calls it “the last piece of the puzzle.”

"It’s easy to make a product
that will detect when
something happens, but you
also need to not detect when
nothing happens"

Expanded product range

At the recent ASIS show, Protech exhibited its expanded range of products, including those from Sorhea and VideoWave. “Our systems are sophisticated and reliable, but they are also cost-effective, especially if you consider the total cost including less-expensive installation,” says Thord.

Thord also emphasises Protech/Sorhea’s spending on research and development – some 8 percent of revenue – which will ensure a flow of technology launches in the near future. “We have sophisticated security products, and we make sure the products are reliable,” says Thord. “It’s easy to make a product that will detect when something happens, but you also need to not detect when nothing happens.”

The largest vertical market for perimeter security has historically been corrections. Protech is also making a mark in airports and transportation, electrical utilities, water treatment and supply, government, and oil and gas refining.

Power and connections

A differentiator for Protech/Sorhea is the ability to provide systems that are not heavily dependent on infrastructure. Perimeter security areas may be remote and far away from network connections and/or power supplies. Protech’s solar-powered and wireless sensors are not burdened by infrastructure requirements.

Protech/Sorhea’s Solaris infrared beam technology provides a virtual fence to detect intrusion. It is wireless and solar-powered and works with a radio mesh network. There is a 300-foot range per system, and local or remote access is available through an integrated web server. Minimal, or even no, infrastructure is required, given the system is solar-powered (with battery backup) and communicates wirelessly. There are no trenches to dig. Anti-condensation caps designed into the product prevent the presence of condensation and ice on the infrared cover, thus allowing for correct functioning in all weather.

called Maxiris, an IR beam
virtual fence that provides
"pinpoint" intrusion detection
in up to three zones

Multiple sensor intrusion detection

Protech also has a wired system called Maxiris, an IR beam virtual fence that provides “pinpoint” intrusion detection in up to three zones. It also needs minimal infrastructure, offers a 300-foot range, and can be accessed locally or remotely through a web server. There are multiple modular styles for expansion.

The company’s Apiris products use multiple sensor technology – the virtual fence combines an active infrared, dual technology sensor and microwave barrier into a single operating interface. The G-Fence/G-Wall fence and wall-mounted system offers accelerometer-based detection. It can detect dynamic cut and climb activity and pinpoints intrusions to within 10 feet. There are both solar and powered models. The Piramid dual technology motion sensors use stereo Doppler technology for targeted detection – direction, speed and distance.

In addition, the Protech VideoWave video analytics object detection and tracking will be available in 2017.

We have a breadth of technology that could be packaged as a total solution or sold independently,” Greg Zuckett, Protech’s Vice President, Sales and Marketing, told me at their ASIS booth. “We offer detection at the outermost perimeter, and then track the intruder as they move closer to the facility.” He says he was pleasantly surprised by the tremendous interest in their products at the ASIS show.

What are the challenges and benefits of mobile access control?
What are the challenges and benefits of mobile access control?

There is a broad appeal to the idea of using a smartphone or wearable device as a credential for physical access control systems. Smartphones already perform a range of tasks that extend beyond making a phone call. Shouldn’t opening the door at a workplace be among them? It’s a simple idea, but there are obstacles for the industry to get there from here. We asked this week’s Expert Panel Roundtable: What are the challenges and benefits of mobile access control solutions? 

Securing a sustainable future
Securing a sustainable future

The UK Government has set out an ambitious ten-point plan, known as the green industrial revolution, with an aim “to forge ahead with eradicating its contribution to climate change by 2050.” This makes our government the first major economy to embrace such a legal obligation. Green recovery Acknowledging climate change and meeting net-zero is a demanding challenge especially for those affected by the pandemic. But the UK Government, with the launch of its aspiring strategy, is investing everything in its power to promote a ‘green recovery.’ Here, Reece Paprotny, Commercial Manager and Sustainability Champion at Amthal, highlights how the fire and security industry has an opportunity to use the current recovery period to explore its own sustainable journey and embrace the significance of environment, economic and social collaboration, transparency, and accountability. Employing sustainable technologies Pressure is mounting on construction to find ways to reduce emissions and help meet net-zero targets The perception is that COVID-19 presents a once-in-a-lifetime opportunity to re-write the existing rulebook. This is riding on the significance of changing public support for more environmentally friendly living opportunities, with associated cost savings, efficiencies, and cleaner industries. Innovative sustainable technologies are the key to kickstart this route to success.  Nowhere can this be seen more than in the built environment, which currently contributes to 40% of the UK's carbon footprint. Pressure is mounting on construction to find ways to reduce emissions and help meet net-zero targets. This is through the entire life cycle of a building, to reduce their impact on the environment from planning stages, through build and demolition. Building the right environment By creating the right policy environment, incentives for innovation and infrastructure, the Government can encourage companies to seize the sustainable opportunities of new technologies and value chains linked to green sectors. They can accelerate the shift of current carbon-intensive economic and industrial structures onto greener trajectories, enabling the UK to meet global climate and development goals under the Paris Agreement on climate change and the 2030 Agenda for Sustainable Development. Transparent working practices Each industry sector is expected to engage and pledge its support to achieve the significant deadlines. Every company can make a difference, even with small steps towards a sustainable future. So whilst elements such as safety and security represent just one component of building the right sustainable environment, it paves the way to opening up our sector to greater efficiencies, transparent working practices, and encourages collaborative use of resources. Sustainability in security The security sector has a significant opportunity to incorporate ‘going green’ into its practices In fact, the security sector has a significant opportunity to incorporate ‘going green’ into their processes, and practices. This is right from product lifecycles to more environmentally friendly work practices when it comes to maintenance and monitoring services. When integrating environmentally friendly practices, starts with the manufacturing and production of the wide variety of systems in operation for the security sector. And some certifications and guidelines can be achieved, such as the ISO 14000 which looks into eliminating hazardous materials being used which in turn will reduce carbon footprint.  Upgrading supply chain process Observing the complete supply chain and working with partners to reduce unnecessary travel, shipments, and transportation of products, can all contribute and create sustainable processes.  In the maintenance and monitoring of products, it is essential installers and security specialists consider their own environmental impacts. Simple changes such as switching company vehicles to electric options for site visits can make a significant difference to climate change and improving air quality. Presenting sustainable ways of disposing of products at the end of their natural lifecycle is key to change in our sector. This is especially in the security industry where many customers will need a complete overhaul of outdated solutions or need systems upgrading due to changing threat levels. Sustainable evolution Progress is being made, specifically in the fire and security industry, in its sustainable evolution. Businesses are trying to develop a reputation for “sustainability” or “good corporate citizenship.” And it has gone well beyond the theory to the practical, where companies recognise activities have an impact on the environment and are also reviewing the social and economic influences. Three pillars of sustainability In a recent interview, Inge Huijbrechts, the Global Senior Vice President for safety and security and Responsible Business at Radisson Hotel Groups sees her vision to combine safety, security, and sustainability. Inge focuses on three pillars, namely, Think People, Think Community, and Think Planet. Think People means that we “always care for the people in our hotels and our supply chain.” So, in outwards communications, safety and security were always part of the Think People focus area. Think Community is caring and contributing in a meaningful way to communities where we operate. Finally, Think Planet makes sure that “our footprint on the environment is as light as it can be in terms of energy, water, waste, and carbon, and making sure that we incorporate sustainability into our value proposition.” Moving forward Apprenticeship schemes are integral to ‘think people’ and have a role to play in the social impact on the security industry There are immediate actions that can be taken by companies in the security industry to support sustainable development, working right from within a company to supporting industry-wide initiatives. From a social perspective, at a foundation level, “Think People’ can see the Living Wage Foundation as an example of a commitment to a team.  This is for businesses that choose to go further and pay a real Living wage based on the cost of living, not just the Government minimum. Apprenticeship schemes are also integral to ‘think people’ and have a pivotal role to play on the social impact on the security industry.  It addresses the sector-wide issue of finding employees with the right mix of skills to collaborate and meet discerning consumer demands for increasingly smart security solutions for homes and businesses. Impact of the full lifecycle of products From an environmental view, or ‘think planet,’ we need to collectively look at all elements of our industry, with a desire to analyse the impact of ingredients used, supply chain, or manufacturing alone, and also consider the full lifecycle of our selected products from creation to end of life. As Jamie Allam, CEO Amthal summarises, “This is a long-term, sustainable investment in our people, our products, and our business based on our values.” “When put together, a social team which feels empowers and operates in environmental optimum working conditions is in a position to provide a great experience to our customers, creating an economic positive difference. It forms the basis of a sustainable sector vision for the security industry-wide to adopt.” Taking action Amthal is taking action based on the ready-made universally agreed UN 17 Sustainable Development Goals. Also known as Global Goals, these are at the heart of the 2030 Agenda for Sustainable Development, adopted by all United Nations Member states. This agenda is a plan of action for people, the planet, and prosperity. By being an early adopter, we believe we can engage with customers, partners, and suppliers on these issues and generate opportunities to innovate for mutual and industry sector benefit. Together, we can contribute to building a more sustainable security sector and future, and contribute to the UK Government’s green industrial revolution.

What is the impact of privacy concerns on physical security?
What is the impact of privacy concerns on physical security?

Adoption of General Data Protection Regulation (GDPR) by the European Union in 2016 set a new standard for data privacy. But adherence to GDPR is only one element, among many privacy concerns sweeping the global security community and leaving almost no product category untouched, from access control to video to biometrics. Because privacy concerns are more prevalent than ever, we asked this week’s Expert Panel Roundtable: What is the impact on the physical security market?
