Organizations are demanding a new level of interoperability among mission-critical security systems. Intelligible audio, the ability to hear, be heard and be understood, is critical to communication, which is essential to the core security processes within an organization, as well as to emergency situations. Intelligible audio provides a platform to optimize various processes, including the use of security officers.

“Our main thrust is to ensure our clients see intelligible and interoperable audio, not as an option, but as instrumental to their budget optimization, stakeholder communication and risk mitigation efforts,” says Jim Hoffpauir, President of Zenitel North America, a manufacturer of intercoms and other communications solutions.

Iintercoms In Building Safety And Security 

The role of intercoms in building safety and security is a given across many markets, and that use is growing. Intercoms are used in campus call boxes, elevators, muster locations, and for emergency notification. The trend is toward video, audio and access control, all tied together. There is also an emphasis on providing intelligible audio in any environment, even demanding ones.

The education market has historically been a large sector for intercoms. Emergency phones and intercoms traditionally have been found throughout education settings, including colleges and universities, where they remain quite popular.

Expanding Markets For Two-way Communication

In recent years, however, their popularity has also grown within the healthcare and mass transit sectors, where their versatility allows authorities to react to emergency situations while also providing a wide range of applications for non-emergency situations, such as car trouble or requests for directions.

“Markets of all sizes and shapes can benefit from a two-way communication solution that can help individuals place calls for assistance with first responders, police departments or customer service representatives,” says David Fleming, Chief Design Officer for Code Blue Corp.

Intercoms For Public And Private Sectors

Aiphone is another intercom manufacturer for which education is a big market. Bruce Czerwinski, U.S. General Sales Manager, Aiphone Corp., says about 80 percent of both public and private K-12 and higher education campuses are using at least one intercom in some form. That percentage grows to nearly 100 percent for hospitals, which are using intercoms as nurse-call stations and at parking facilities, exterior door entries, nurseries and pharmacies, he says.

"About 40 percent of commercial units – from strip malls to large, multi-tenant campus settings –
are using intercoms"

Up to 70 percent of larger multi-family facilities are also using intercoms. And that percentage is even higher in older, heavily populated Eastern cities. Many locales have laws mandating the use of audio and video intercoms on buildings beyond a threshold number of units. About 40 percent of commercial units – from strip malls to large, multi-tenant campus settings – are using intercoms, says Czerwinski.

In the past year, Aiphone’s emergency stations have become very popular, particularly in campus settings; both commercial and higher education. Also, a growing number of unmanned parking garages are using the stations to allow patrons to immediately reach first responders or security personnel.

Each of these markets still has growth potential, but by its sheer size, the commercial market offers the greatest opportunities, according to Aiphone.

Video-Enabled IP Intercoms

Intercom usage differs widely in various global markets, according to Craig Szmania, CEO of 2N USA, a manufacturer of IP intercoms. In the North American market, intercom usage is relatively low compared to the Europe, Middle East, and Africa (EMEA) region, where intercoms are a more mature market. Security, convenience, systems integration and IP-versus-analog adoption are driving usage and growth to more than 20 percent year-over-year. More and more video-enabled IP intercoms are seen as an integral part of a system wide security and video solution, according to Szmania.

“Our intercom portfolio targets all the major verticals, but we have had particular success in the education sector – K-12 and universities,” says Szmania. “These end users are looking for specific features in securing their campuses, providing convenience to their administrators, employing programmability for differing use scenarios throughout the campus, and integration to their telephony or other systems.”

Szmania says the latter point is becoming a particular need in light of a requirement for campus-wide communication and coordination in emergency situations. “Our intercoms integrate seamlessly with third party solutions such as Cisco’s telephone systems that are the communication backbones of many schools and campuses,” he adds.

IP-based Solutions In Residential Verticals

Considering near-term growth potential, single family and multi-tenant residential verticals have fantastic opportunities for increased usage of door stations/intercoms in the United States, according to Szmania. The company has entered this space over the last several years and has grown to be a market leader in IP-based integrated solutions, especially in the home automation space. The adoption of IP networked solutions for condominiums and apartments is just taking off, driven in part by consumer demand for mobile-anywhere video, audio and door control. The service is also a driver for integrator/dealer adoption of the technology to provide recurring monthly revenue (RMR).

2N has also achieved triple-digit growth in commercial building installations over the past two years. Building owners, IT departments and security managers want and need a networked solution for control and security. 2N’s open platforms are a good fit, says Szmania.

Are Privacy Concerns Stifling Innovation in Security?
Are Privacy Concerns Stifling Innovation in Security?

Facial recognition is the latest technology to be targeted because of concerns about privacy. If such concerns cloud the public perception, they can be harmful to technology markets. Whether the concerns are genuine or based on misinformation is often beside the point; the practical damage has already been done. But beyond market demand, what is the impact of privacy concerns on technology innovation? We asked this week’s Expert Panel Roundtable: Are privacy concerns stifling innovation in security and related markets? 

Building Security: How Audio Tells the Whole Story
Building Security: How Audio Tells the Whole Story

Every building starts with the entrance. A solid enterprise risk mitigation and security strategy include protecting that entrance. Often, risk mitigation strategies protecting the entrance have included high-resolution video surveillance cameras, video management systems, and access control solutions. But that strategy and set of security solutions only tells part of the story. Imagine a security guard who is protecting a facility after hours, when an individual approaches the entrance and seeks to gain access. The security guard can pull up the video surveillance feed and see the individual and his movements, which appear to be suspicious. But he also needs to hear him in order to decide the next decisions and actions. Does he escalate the situation, calling for backup and for first responders’ response, or does he allow the individual access to the building because he works there and is authorized to enter?   Meet high-definition voice What the security guard needs is to be able to hear and to communicate with that individual. All enterprise security systems need three primary components in order to successfully protect the entrance and to mitigate risk – access control, video surveillance, and the ability to hear and communicate. Each component plays an integral role in supporting a unified security system, and without all three, the security system is not complete. Access control can be thought of as the brains of a security system by holding data and permissions. It serves as the arms and hands of the system; it can either keep someone out or invite them in. IP video allows a security team to remotely position a set of eyes anywhere an IP camera can be placed on a network. With a video management system, security teams can see what is happening and decide how to respond. However, with remote viewing, the event may be over by the time security physically responds.  Audio adds interactivity That three-component enterprise security system – comprising IP video, access control, and high-definition voice working together mitigates risks and provides value. It also means that security is interactive. Security teams talk and listen to the person that’s seen on a video surveillance system, no matter where the location or how remote. If the person is lost or simply needs assistance, security personnel can talk to them and provide direction and reassurance. Even more, in an emergency, an interactive solution becomes a critical life-saving tool, as it provides data that can be shared between security, police, emergency services, and more. Audio can also detect voices, noises, breaking glass, or other sounds that are not within direct view of a video camera. An interactive security system creates an informed response, by providing real-time situation awareness management. Post-event, it supports forensics and investigations to mitigate future security incidents.  Audio and COVID-19 We are living in extraordinary times. As businesses begin to reopen and stay open, they are looking for any tools that can help them overcome the enormous challenges they face. In buildings and facilities, the COVID-19 pandemic has created a new security perimeter, one that demands contactless access with entry and exit, and that has also created a new duty of care for security professionals. Now more than ever is the need to interact and communicate with individuals moving in and out of doors and spaces without physical intervention. Intelligent communications, integrated with contactless access control, can help a business to comply with pandemic safety guidelines and ultimately, reopen for business and stay open.  COVID-19 has also increased the need for clean-room isolation and quarantine spaces, sometimes in areas not originally intended for that use, where risk of infection is high, and equipment must be easily disinfected between patients. Here, purpose-built cleanroom intercoms, providing clear touchless communications despite the noisy environment, have emerged as critical tools for enabling patient care while reducing the need to enter the contaminated space. For example, voice communication can enable hospital staff to verify identity and to communicate with patients without entering the isolated and infectious environment, which can save on personal protective equipment (PPE) and reduce the amount of exposure to the virus. In non-emergency healthcare facilities, such as medical centers, voice can effectively relay information to building occupants and visitors for screening purposes. Visitors can be seen and heard. For example, a patient who seeks access to a medical center for an appointment can hear important instructions from a nurse via the intercom solution. Seeing the person that you talk to is one thing but hearing them conveys a much better sense of closeness, making it possible to maintain a high level of security and customer service.  The whole story Today’s security systems should no longer simply involve video surveillance cameras generating feedback and images to a security guard. Instead, a new ecosystem for enterprise security and risk mitigation has emerged, and it’s one that involves video surveillance, access control, and high-definition voice. That ecosystem can ensure well-rounded and responsive information management and security platform, all communicating with each other and offering actionable insight into risks and potential physical breaches. Audio is the new value hub of the connected and intelligent school, campus, building, correctional facility, and more. Simply put, a silent security system cannot be an effective security system. In every situation, it is crucial for all security professionals to mitigate risk, no matter what they are protecting. This emphasizes the need to hear, be heard, and be understood in virtually any environment.  

Inclusion and Diversity in the Security Industry: ‘One Step at a Time’
Inclusion and Diversity in the Security Industry: ‘One Step at a Time’

Historically, concerns about inclusion and diversity have not been widely discussed in the security market. In the last couple of years, however, the Security Industry Association (SIA) and other groups have worked to raise awareness around issues of diversity and inclusion. Specifically, SIA’s Women in Security Forum has focused on the growing role of women in all aspects of security, and SIA’s RISE community has focused on “rising stars” in an industry previously dominated by Baby Boomers. The next generation of security leaders There is a business case to be made for diversity and inclusion, says a report by McKinsey & Company. According to the management consulting company, gender-diverse companies are 24% more likely to outperform less diverse companies, and ethnically diverse companies are 33% more likely to outperform their less diverse counterparts. Furthermore, the “next generation of security leaders” – employees under 30 – are particularly focused on diversity and inclusion. Diversity refers to the traits and characteristics that make people unique A panel discussion at ISC West’s Virtual Event highlighted aspects of inclusion and diversity, starting with a definition of each. Diversity refers to the traits and characteristics that make people unique. On the other hand, inclusion refers to the behavior and social norms that ensure people feel welcome. “We are all on a journey, and our journey takes different paths,” said Willem Ryan of AlertEnterprise, one of the SIA panelists. “There are opportunities to improve over time. We can all change and increase our ability to have a positive impact.” Industry responsibility The industry has a responsibility to the next generation of industry leaders to address issues of inclusion and diversity. Forbes magazine says that millennials are more engaged at work when they believe their company fosters an inclusive culture. So the question becomes: How do we unify and create opportunities to work with and champion tomorrow’s leaders? SIA is driving change in our industry to achieve that goal. More women are active in SIA than ever before. The SIA Women in Security Forum now has 520 members, said Maureen Carlo of BCD International, the SIA Women in Security Forum Chair and another panelist. Also, more women than ever are chairing SIA committees and serving on the SIA Board of Directors. More women than ever are chairing SIA committees Overcoming unconscious bias Former SIA Chairman Scott Shafer of SMS Advisors, another of the panelists, noted that SIA awarded the Chairman’s Award to the Women in Security Forum in 2019, and to the RISE community steering committee in 2020. “There are lots of ways we are seeing the elevation of women and ethnic groups in the security industry,” said Shafer. One topic of interest is the problem of “unconscious bias,” which can be overcome by looking at something through some else’s lens. Ryan suggested use of the acronym SELF –  Slow Down, Empathize, Learn, and Find commonalities. Ryan recalled the value of being mentored and having someone shepherd him around the industry. “Now I want to give back,” he said. “We need to look at the things we can change in ourselves, in our company, in our communities, and in our industry. Change comes from the bottom and the top.” Increasing representation “It takes all of us to increase representation everywhere,” said Kasia Hanson of Intel Corp., another panelist. “We have in common that we are all human beings. Let’s make sure the next generation all have opportunities.” Diverse companies can attract better talent Moving forward, the panelists urged the industry to get involved and create opportunities because inclusion drives diversity. Diverse companies can attract better talent and attain a competitive advantage. Awareness of unconscious bias, and working to eliminate it, is an important element of change. Despite the progress the security industry is making, change continues to be incremental. As Ruth Bader Ginsburg has said, “Real change, enduring change, happens one step at a time.”
