Why Security Should Embrace the Internet-of-Things

Smarter Connectivity Is the Name of the Game

In the world of fashion trends tend to come in cycles. Wait a decade or two and your old wardrobe is suddenly back in style. Sometime this is true in the world of technology as well. Old ideas often resurface in newly imagined way. Look at the concept behind the Internet of Things (IoT). It is actually rooted in yesterday’s thin client and thin server technologies popular in the mid 1990’s. While physical security pundits may wonder how IoT will affect the industry going forward, they only need to look to the past. As more IP-based security devices inevitably replace aging analog systems, security products manufacturers face the ongoing challenge of helping users integrate the growing wealth of information generated by the IoT into meaningful business intelligence.


Looking Back on a Forward-Thinking Trend

Our framework for designing smart network devices began in 1995. Back then thin-client technology was a growing trend driven primarily of Oracle and Netscape. It gave companies a way to deliver greater processing power to multiple users by having them share a common high-capacity server. A thin-client solution not only reduced the total cost of ownership for the overall system, relying on a central resource was an easy way to maintain a high level of computational services across the enterprise.

Axis reimagined that “thin” concept and invented something we called “Thinserver Technology.” Our goal was to make the network smarter so that devices sharing the infrastructure would not only be more economical to own but easier to manage as well. It was a logical next step for broadening our business, which at the time focused solely on print servers – small network-enabled devices that connected printers to networks. Thinserver quickly became the framework for developing server apparatus for connecting almost anything to the network – optical storage and home automation systems, even model trains and Christmas tree lights.

But the most important Thinserver products developed back then were the networked cameras and video encoders because they eventually reshaped an entire industry. Today tens of millions of network video devices have been installed around the world from a vast array of manufacturers. Thanks to the networking abilities it became practical to deploy video over larger areas which made city surveillance an application affordable to every city!

Looking back on the white papers written 20 years ago, I discovered a remarkable similarity between early Thinserver technology and how IoT is trending today. In hindsight, the millions of print servers we shipped in the late 90s were probably the first IoT devices deployed in volume.

The first network cameras were introduced in 1996 and by 1999 they were embedding LINUX to create an open architecture that would finally make network surveillance devices practical solutions for the security industry. This open approach to system development not only became our business model, it launched an entire network video revolution.

In recent years, with the excitement about IoT technology heating up, there is an opportune for security products based on the IoT concept. These can collect and automatically share useful data with other IoT devices. As network-based devices they could be monitored remotely. And the connectivity between devices would provide end users more complete situational awareness across multiple locations.

To that end comes IP-enabled access control system that could transform a door into an intelligent IoT device. With its IoT ability, the network door controller can be configured for a cloud environment where access control becomes part of a hosted system. This operating model is particularly suitable for environments with many remote doors that need the added security of integrated video. The network door controller capitalizes on the benefits of PoE to decrease installation costs and increase system reliability. Overall, an IP-based door controller is less complicated to maintain, offers greater flexibility and scalability and a lower total cost of ownership than its analog counterpart.

To augment the idea of IP cameras and network door controllers accessory and enhancement devices such as IP speakers and horns can be added. Being yet another IoT device, for example, the horn speaker can be triggered automatically by video motion detection and intrusion sensors to play a pre-recorded audio message which can be useful for preventing graffiti or keeping parks empty at night. When integrated with a video management system, a remote operator can even speak directly to any intruders saving cities lots  of money. Because of the IoT capabilities and industry open standards, it easily integrates with other open standards IoT device. Best of all, with speakers that supports SIP can be assigned a regular phone number like any other VoIP telephony device.

Other areas where the IoT can play an important role is in emergency help stations. By having a video emergency help station you can be sure to have much better feedback and understanding of the situation. If the door station supports SIP it can be easily integrated with any emergency phone system giving the right priority to each alert. In addition, the savings from installation and system integration are tremendous.


Keeping an Eye on Other Technology Game Changers for IoT

While basing IoT devices on open standards has certainly changed the physical security landscape, one of the biggest game changers when it comes to system costs has been Power over Ethernet. Being able to use the same cable to both power the IoT device and transmit data has significantly reduced installation costs by decreasing the amount of cabling needed for the project and shortening the amount of man-hours needed to install devices. With PoE there is no need to home run expensive coax cables to a recording device or a security monitoring center as you would with analog video cameras, card key systems and intercoms. With PoE in the network topology you just run a single cable from the IoT device to a centralized PoE switch. The PoE switch runs a single cable back to the recording device or security center to stream the data from all its connected IoT devices.

Another significant game changer has been cloud-connected services. As network-based technology IoT devices are excellent candidates for managed services. The only upfront investments end users have are the IoT devices themselves. The service provider handles the rest of the system – data storage, a secure web portal for user access, system upgrades, authorized user directories, ongoing maintenance, etc. – for a fixed monthly fee. By moving surveillance, access control and other physical security systems from a capital expense to an operating expense end users can reap the benefits of IoT for a much lower cost.


IoT Is Everywhere

IoT has certainly proliferated in the consumer world. Smart thermostats send homeowners alerts while they are away on vacation. Nanny-cams let parents keep an eye on their children while still at work. There are even smart refrigerators that automatically order groceries for the household when supplies run low.

In the security world, IoT is helping businesses manage all their security systems – from intrusion sensors and fire alarms to video surveillance, access control, loudspeakers, emergency stations and video intercoms – as a single cohesive platform. IoT monitoring devices are even being linked to environmental controls to ensure that a building’s HVAC systems operate within set parameters. Can smart toasters in the break room be very far behind?
