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.”

More and more video-enabled IP intercoms are seen as an integral part of a system wide security and video solution

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.

COVID-19 Worries Boost Prospects Of Touchless Biometric Systems
COVID-19 Worries Boost Prospects Of Touchless Biometric Systems

Spread of the novel coronavirus has jolted awareness of hygiene as it relates to touching surfaces such as keypads. No longer in favor are contact-based modalities including use of personal identification numbers (PINs) and keypads, and the shift has been sudden and long-term. Both customers and manufacturers were taken by surprise by this aspect of the virus’s impact and are therefore scrambling for solutions. Immediate impact of the change includes suspension of time and attendance systems that are touch-based. Some two-factor authentication systems are being downgraded to RFID-only, abandoning the keypad and/or biometric components that contributed to higher security, but are now unacceptable because they involve touching. Touchless biometric systems in demand The trend has translated into a sharp decline in purchase of touch modality and a sharp increase in the demand for touchless systems, says Alex Zarrabi, President of Touchless Biometrics Systems (TBS). Biometrics solutions are being affected unequally, depending on whether they involve touch sensing, he says. Spread of the novel coronavirus has jolted awareness of hygiene as it relates to touching surfaces such as keypads “Users do not want to touch anything anymore,” says Zarrabi. “From our company’s experience, we see it as a huge catalyst for touchless suppliers. We have projects being accelerated for touchless demand and have closed a number of large contracts very fast. I’m sure it’s true for anyone who is supplying touchless solutions.” Biometric systems are also seeing the addition of thermal sensors to measure body temperature in addition to the other sensors driving the system. Fingerscans and hybrid face systems TBS offers 2D and 3D systems, including both fingerscans and hybrid face/iris systems to provide touchless identification at access control points. Contactless and hygienic, the 2D Eye system is a hybrid system that combines the convenience of facial technology with the higher security of iris recognition. The system recognises the face and then detects the iris from the face image and zeros in to scan the iris. The user experiences the system as any other face recognition system. The facial aspect quickens the process, and the iris scan heightens accuracy. TBS also offers the 2D Eye Thermo system that combines face, iris and temperature measurement using a thermal sensor module. TBS's 2D Eye Thermo system combines face, iris and temperature measurement using a thermal sensor module Another TBS system is a 3D Touchless Fingerscan system that provides accuracy and tolerance, anti-spoofing, and is resilient to water, oil, dust and dirt. The 2D+ Multispectral for fingerprints combines 2D sensing with “multispectral” subsurface identification, which is resilient to contaminants and can read fingerprints that are oily, wet, dry or damaged – or even through a latex glove. In addition, the 3D+ system by TBS provides frictionless, no-contact readings even for people going through the system in a queue. The system fills the market gap for consent-based true on-the-fly systems, says Zarrabi. The system captures properties of the hand and has applications in the COVID environment, he says. The higher accuracy and security ratings are suitable for critical infrastructure applications, and there is no contact; the system is fully hygienic. Integration with access control systems Integration of TBS biometrics with a variety of third-party access control systems is easy. A “middleware” subsystem is connected to the network. Readers are connected to the subsystem and also to the corporate access control system. An interface with the TBS subsystem coordinates with the access control system. For example, a thermal camera used as part of the biometric reader can override the green light of the access control system if a high temperature (suggesting COVID-19 infection, for example) is detected. The enrollment process is convenient and flexible and can occur at an enrollment station or at an administration desk. Remote enrollment can also be accomplished using images from a CCTV camera. All templates are encrypted. Remotely enrolled employees can have access to any location they need within minutes. The 3D+ system by TBS provides frictionless, no-contact readings even for people going through the system in a queue Although there are other touchless technologies available, they cannot effectively replace biometrics, says Zarrabi. For example, a centrally managed system that uses a Bluetooth signal from a smart phone could provide convenience, is “touchless,” and could suffice for some sites. However, the system only confirms the presence and “identity” of a smart phone – not the person who should be carrying it. “There has been a lot of curiosity about touchless, but this change is strong, and there is fear of a possible second wave of COVID-19 or a return in two or three years,” says Zarrabi. “We really are seeing customers seriously shifting to touchless.”

How To Use Threat Intelligence Data To Manage Security In The Age Of COVID-19
How To Use Threat Intelligence Data To Manage Security In The Age Of COVID-19

COVID-19 has already had a huge impact on the global economy. According to Statista, GDP growth globally will drop from around 3% to 2.4% - equivalent to a drop of around $35 trillion worldwide. In sectors like oil and gas, the impact is particularly acute: IHS Markit predicted that the reduction in oil consumption due to COVID-19 has led to a first-half surplus of 1.8 billion barrels of crude oil. The macroeconomic trends around these worldwide sectors point to harsher economic conditions and recession. For companies in the oil and gas sector running complex operations around the world, this will lead directly to tougher trading environments and a lot of necessary belt-tightening when it comes to costs around operations. Indirectly, the potential recession could cause more civil unrest and security threats for them as well. To cope with these potential challenges, companies will have to look at how they can maintain security for their operations and prevent risks as much as possible. Taking a contextual approach to physical security With these two goals in mind, looking at threat intelligence data should be considered. Threat intelligence refers to a set of data that can be used to judge current and future trends around risks, from everyday crime or political changes through to larger events like civil unrest, terrorism or the current pandemic. Based on data around these issues, companies can make better decisions on how they invest and manage their security posture in advance. Behind this overall approach, however, there are a significant number of moving parts that have to be considered. This includes where the data comes from, how it is used, and who is using the data. Companies can make better decisions on how they invest and manage their security posture The first consideration for threat intelligence is where data comes from. Typically, companies with large oilfields or refinery operations will have large investments in physical security to protect these environments, and part of this spend will include intelligence on local market, political and security conditions. Using this forecast data, your security leadership team can ensure that they have the right resources available in advance of any particular problem. This data can come from multiple sources, from social media data and crowdsourced information through to government, police and private company feeds. This mass of information can then be used to inform your planning and decision making around security, and how best to respond. However, one issue for oil and gas companies with distributed operations is how much data they have to manage over time. With so many potential sources of information all feeding back in real time, it’s hard to make sense of what comes in. Similarly, companies with international teams may have different sets and sources of data available to different parts of their organizations - while each team has its own view of what is going on, they may be missing out on contextual data from other sources held by neighbouring teams or by the central security department. Without a complete picture, it is easy to miss out on important information. Making threat intelligence smarter To solve this problem - and to reduce the costs around managing threat intelligence data - centralizing your approach can make it easier to provide that context to all your teams and stakeholders. Rather than letting each team set up and run their own threat intelligence approach, centralizing the data and letting each team use this can reduce costs. More importantly, it can improve the quality of your threat intelligence approach overall. By applying a combination of algorithms and security analysts to evaluate threat intelligence centrally, you can improve the quality of the data that you have coming into the organization in the first place. This approach provides higher quality data for decision making. However, a centralized approach is not enough on its own. Local knowledge and analysis is always useful. Consequently, alongside any centralization approach you have to have better filtering and search capabilities, otherwise you risk teams not being able to get the information that is particularly relevant and timely to them. This approach of bringing together centralized management of data feeds with more powerful tools for local teams to find what they want and get that access in real time represents the best of both worlds. Planning ahead Scenarios vary from a best case return to pre-crisis revenues of $50 to $60 per barrel by 2021 or 2022 According to consultancy firm McKinsey, the oil and gas sector faces an enormous challenge over the next few years. Scenarios vary from a best case return to pre-crisis revenues of $50 to $60 per barrel by 2021 or 2022, through to a worst case scenario where demand never returns and the industry has to undertake managed decline around some assets and look for new market opportunities in others. Whatever scenario plays out in the real world, security for existing assets will be a continued requirement. Planning ahead using threat intelligence data will be essential whatever happens. To help reduce costs and improve data quality, centralizing this approach will help. Without this mix of global oversight and local detail, companies will find their operations hampered and wrong decisions are made. It’s only by applying threat intelligence data in the right context that security teams will be able to keep up with the challenges of the future.
