Greater connectivity, security software enhancements, more customization, and better sound quality are some of the enhancements driving the intercom market.

An advantage now offered on Code Blue’s emergency speakerphones include self-diagnosing software that monitors the status of the phones and their components — microphones, buttons and speakers — and delivers instant notifications if there is ever an issue. Code Blue phones also come with full duplex capabilities with echo cancelling, sometimes known as open duplex, which allows the caller and first responder to communicate simultaneously and eliminates buzzing and static.

IP-Based Networking Systems

Code Blue also builds its phones to open standards like Session Initiation Protocol (SIP), which allows calls to be easily processed with a wide variety of systems and software solutions, says David Fleming, Chief Design Officer for Code Blue Corp.

Networking has impacted the intercom market, with the advent of IP-based systems. The corporate network now makes it possible to share information and to control units from a few yards to thousands of miles away, according to Bruce Czerwinski, U.S. General Sales Manager, Aiphone Corp. For example, central command center guards can monitor and allow entrance to any networked satellite or unmanned facility 24/7.

Multi-Site Communications

Networks have also spawned mobile apps that allow roaming guards to use smartphones and devices to maintain total control of an intercom system while away from the master station and on the Wi-Fi. And network paging is another recently added communications tool, valuable for routine announcements or emergency instructions.

"Voice is becoming the killer app for serving the safety and security needs of employees and customers"

“We’re now able to offer large-scale multi-site communications using intercom systems,” says Czerwinski. “That’s not just connecting a few buildings on opposite sides of a campus quad, but all those separated by state lines, even across the country.”

As markets and customers served by intercom products continue to evolve with new needs requiring new solutions, intercom companies continually poll the market and develop new and interesting solutions for these needs.

All-In-One Physical Access Control Solution

Because intercom manufacturer 2N’s products are often used as part of a physical access control system, convenience and security are key attributes. Bluetooth technology will be employed heavily. 2N has just introduced its Bluetooth access control reader for both standalone access control and integrated into 2N’s VERSO door station.

The technology is based on Bluetooth Low Energy (BLE) technology, which offers long-range detection (up to 10 metres), low energy consumption and ‘banking’ level security. It can be combined with other technologies — near field communication (NFC) and radio-frequency identification (RFID) — for an all-in-one solution.

Mobile Video App For Door Intercoms

2N has also launched a mobile video app/service. It enables a consumer’s smart device to be used as an interface to the door intercom, allowing video calls from anywhere in the world, door access control, and as an ‘always on’ video and audio surveillance system. Notifications can be launched automatically; for example, if someone approaches the homeowner’s door, porch, or surrounding area. A low-cost all-in-one door station — Base — has been released for the residential and small business space, including HD video, audio, and door control but in a simpler-to-install and lower-cost format.

Zenitel’s Customer Intercom Station Kit enables customers to build their own stations

In the spring, 2N is releasing a Z-wave networked door control solution that’s easy to install and extends the reach of an access control system.

Off-The-Shelf Communication Devices

Jim Hoffpauir, President of Zenitel North America, says the intercom company offers a choice of either off-the-shelf communication devices or components to enable customized stations to be built based on a customer’s aesthetics or form and/or function needs. Users also must be heard and be understood, says Hoffpauir.

“We spend millions of dollars in research and development on the intellectual property that defines and sets the standard for intelligible voice audio in the communications industry,” he says. “And we focus on embedding that capability with strategic alliances in access control, video and unified communications.”

“Voice is becoming the killer app for serving the safety and security needs of employees and customers,” says Hoffpauir. “We want to create new interoperable solutions such as our networked HD Video Door station that acts as a communication device as well as an access control station.” It has two-way communication for 24/7 video identification and support for IP phone or unified communications through SIP.

Intelligible Critical Communications Solutions

Zenitel’s Call Access Panel manages intelligible critical communications through a security operations center or control room. The panel has a small footprint with pre-programmable buttons for instantaneous emergency or mass notifications to all intercom stations or IP public address, alarms, or horns. And it is SIP-compatible for unified communications.

Changes in hardware and software are transforming the intercom market, as are changes in how systems are combined and configured.

There is also a trend toward more discernment in terms of audio quality and system performance. Including an evaluation ‘scorecard’ in a request for proposal (RFP), for example, can ensure there is a clear way to evaluate systems being considered. “We are teaching the market there can be a legitimate scorecard on intelligibility,” says Dan Rothrock, SVP of Global Strategic Alliances, Zenitel North America. “You may not know you have bad audio until something bad happens, and it’s too late.”

Open Options Paves the Way for New Customers in Access Control
Open Options Paves the Way for New Customers in Access Control

For more than 22 years, Open Options, Addison, Texas, has developed access control solutions that connect to leading security technologies to deliver a full-scale solution based on each customer’s unique needs. In 2018, Open Options was acquired by ACRE, which already owned the Vanderbilt and ComNet brands. To find out the latest, we interviewed Chuck O’Leary, President of Open Options. Q: It has been two and a half years since Open Options was acquired by ACRE. Briefly describe that transition and how the company is stronger today because of it. O’Leary: The ACRE transition really focused on integrating our access control solution, DNA Fusion, with Vanderbilt Industries technologies in order to further our reach in the market and enhance our portfolios. With their support, we have been able to accelerate innovations and expand our global reach. Overall, it has been a great experience to be a part of the ACRE organization, and it has opened the doors to new opportunities for us both here in the states and globally.  Q: What is "Connect Care" and how does it benefit integrators and/or end user customers? O’Leary: For those unfamiliar with the world of access control, it can often be a little overwhelming when first introduced; however, we strive to make our products as easy to use and intuitive as possible, with Connect Care being no different. Connect Care is a system that has been specifically designed to create the most connected experience in the security market Connect Care is a system that has been specifically designed to create the most connected experience in the security market. It serves as a 24/7 bridge from our customers to services like technical support, platform support, professional services, and training. By providing these options for our customers, we can better empower them with the knowledge and expertise of our DNA Fusion access control system and ensure their success with the product.  Q: Who are the new customers entering the market for access control systems in the wake of the pandemic, and how should they be approached/managed differently? O’Leary: Over the last year, there has been a huge demand for access control systems as remote work increased due to COVID-19, and even now, as employees and students are heading back into the offices and schools. Organizations are realizing that having an outdated security system is no longer robust enough for the rapid advancement of technology that we witnessed over the course of the pandemic, and really the past few years. For those who are just dipping their toe into a new access control deployment, the most important thing they can do is to search for a provider who has a solution that is easily integrated, scalable, and provides excellent training and resources. Q: Define the term "touchless access control" and explain why it is gaining a higher profile in the post-pandemic world. O’Leary: The interesting thing about access control is that it has almost always been touchless. Many organizations are looking for robust solutions that are touchless and can be utilized remotely, and it's fairly easy to understand why a solution like this would become widely popular because of COVID-19. Integrators are searching for access control systems that will serve as a proper solution for organizationsThe process of using access control to streamline security infrastructures is not a new concept by any means, but due to the rapid development in technology over the past few years, more integrators are searching for access control systems that will serve as a proper solution for organizations, while still supplying the touchless and remote-based features. Q: What do you see as the future course of the changing technology trends we see in today's market (such as mobile credentials, cloud-based systems, cybersecurity, etc.)? O’Leary: As we continue to tread through the different technological developments in the market today, we are noticing that mobile credentials and biometrics are becoming increasingly popular. As cybersecurity and mobility continue to become more important, we are also seeing the rapid jump to the cloud. By utilizing cloud-based systems, an organization is not hindered by a lack of storage or old software and gains the flexibility to scale their security system as their business grows. Q: How will the access control market look different five years from now versus today? What about 10 years from now? O’Leary: Within the next five years, I suspect that access control will continue to make the move towards cloud-based systems and utilize mobile credentials and biometrics. In 10 years, I think all access control will be open platform and many more organizations will embrace cloud solutions for increased functionality. Also, innovations will continue to be the drivers behind new deployments with some installations being biometrics only and include recognizing fingerprints, retina scans, facial recognition, and voice. Q: What is the biggest challenge currently facing the access control market, and how should manufacturers (including Open Options) be addressing the challenge? O’Leary: One of the biggest challenges facing the physical access control market is organizations actually making the shift to more up-to-date access control systems. Organizations are looking to adopt more digital-focused access control experiencesOrganizations are looking to adopt more digital-focused access control experiences — ones that are focused on integration, newer features, cybersecurity, and ease of monitoring. Access control manufacturers should be addressing this challenge by creating integratable, scalable systems that are easily managed and provide a structured, streamlined approach for an organization’s security infrastructure. Q: What is the biggest misconception about access control? O’Leary: Access control is not a one-size-fits-all solution, and some organizations might have different standards or assets that need protection. This is why it's vital to know the risks your organization faces when speaking with access control providers — to ensure the best possible outcome for your specific needs. It's important to remember that whatever access control system is chosen should proactively mitigate any risks, be easily taught to and successfully used by employees, and be scalable with your organization. No matter the line of work, a proper access control system should streamline the security infrastructure and lessen stress on the security team and employees.

Automatic Gates – The Latest Development In Access Control
Automatic Gates – The Latest Development In Access Control

Automatic gates remain an increasingly popular security choice for family homes, business premises or public buildings – anywhere that full control over access is needed. While there is much to consider for installers when advising clients on the right solution for their property, from the size, weight and cost of a gate system, it’s useful to be aware of the latest developments in the market, as this can help to find the right option to fit their needs. The need for speed Gates can be automated to either swing or to slide open, and there are many factors to take into consideration, when advising on which option to use. However, swing gate motors tend to be slower than the speeds achievable for sliding gates, which means the latter are usually more popular, especially for commercial sites where timing can be among the more important factors. One of the most recent developments in the sliding gates market is the introduction of faster motors One of the most recent developments in the sliding gates market is the introduction of faster motors, such as those from Bft Automation, which allow for opening and closing at a quicker speed than has previously been achievable. Fast authorized access control From a security point of view, the ability to allow people and goods in and out of a property at a quicker pace reduces the risk of unauthorized entry, while waiting for a gate to close – an important consideration in both commercial and residential contexts. Other benefits of a faster motor include reduced waiting times. This can be particularly useful for properties in busy areas, where a vehicle could risk blocking traffic, while waiting to turn into a site controlled by a slower gate. Faster motors Also, a faster motor could potentially reduce the risk of an accident from vehicles entering a property at speed. For example, this might happen if someone was making their first visit to a property situated off a fast road in an unfamiliar area. Beyond these practical considerations, in today’s fast-paced world, people aren’t as used to having to wait for things and this applies to the time it takes to get in and out of their own property. So, security benefits aside, faster motors are likely to be more appealing for clients who have sliding gates fitted to their domestic property and who prioritize convenience. The choice of which of the new faster motors to use will be impacted by a number of factors, including the weight of the gates. Essentially, the lighter the gate is the higher the speed achievable. And, as always, it’s important to make sure that any installation complies with safety regulations. Intelligent torque management systems A further development in access control technology includes intelligent torque management systems A further development in access control technology includes intelligent torque management systems, which update the level of torque required to perform the gate’s operation, allowing it to work at the optimum level, regardless of weather conditions, temperature or the degree of wear and tear on the device. Depending on the typical weather conditions experienced at the site and the anticipated frequency of use, it’s worth looking at options that take these factors into account. Importance of security rights In some scenarios, it’s important for particular individuals to have security rights. In which case, there are motors available that come with personalized keys, which are unique, providing an additional level of security. Installers often face the challenge of fitting gate motors in confined spaces, potentially making for a time consuming and technically demanding task. Available space When you only have a small space to work with, simple details can go a long way to helping you. For example, by putting the fastening screws on the front of a motor’s casing, installation and maintenance are easier and more convenient, even in particularly compact areas. Working with suppliers that offer more than just a manual means you’ll have access to advice and support on how new products work in practice and what you need to consider before advising on an installation.
