Putting Wireless to Work for You Part 1: Intrusion

Improved range and reliability, along with comparatively low installation costs, are making wireless security more than just practical for commercial projects. In many cases, it’s a necessary choice for integrators to remain competitive and profitable.


“Don’t overlook the self-healing benefits of wireless networks. That’s a real advantage over wired security systems. If a wire corrodes, is damaged or otherwise rendered inoperable, that’s it. There’s no communication to that point and it has to be repaired,” says Yarger. “But if a network can heal, it reroutes the messages through a path that works.”

Ensuring Satisfaction

The best wireless systems are designed to provide maximum satisfaction for their users. Once a wireless network infrastructure is in place, devices can be moved to allow for changing floor plans and the movement of large obstacles that may interfere with the signal. An example would be those found in warehouse environments.

Because it’s a simple matter to add devices, more applications can be added to the intrusion system resulting in more sales opportunities. It’s also extremely cost-effective. Being able to amortize the cost of the wireless infrastructure across multiple applications presents the end user with a more efficient way to manage the operating expenses of the facility — and an additional point of differentiation for an installer’s bid.

Integrating security pendant or panic button devices wirelessly gives employees the ability to trigger an alarm from anywhere in the building, which is impossible with a wired system. Additionally, pendants can be used as safety buttons for workers in case of an accident. This added measure of security works alongside the intrusion system and enhances the overall value and dependability of the wireless network.

Wireless installations enable easy and inexpensive reconfiguration of the endpoints if the physical layout of the environment changes. Museums often install a wireless system to secure display cases that are part of traveling exhibits. If they already have a wireless system securing the entire premises, it’s as easy as adding additional sensors. Or in cases where a hardwired system is primary, it’s just as simple to add the sensors and operate a hybrid security system.

Wireless also simplifies system upgrades. A majority of locations have an existing security system in place, but successful enterprises are usually performing a number of upgrades somewhere in their facilities.

As clients’ needs evolve, organizations can add wireless mesh and its endpoints to an existing system and panel. Clients that are able to adjust their systems as needed are pleased with the ability to have a wireless system in place that provides not only added value but increased customization.

Overcoming Challenges

During the past decade, wireless has become commonplace in our lives. Most everyone carries a cell phone or uses a wireless Internet connection. The acceptance of this technology has contributed to the changing perceptions about its use for security. Wireless security has advanced to the point where any past concerns about interference, reliability or range have been all but eliminated.

The wireless communication environment can be a perilous place due to signal crowding, noise, interference and physical obstructions. The rise in popularity of wireless communication devices such as radios, telephones and pagers along with wireless Internet devices that operate in the unlicensed radio frequencies further exacerbate interference issues.

Secondary effects associated with these devic
es such as interference and multipath propagation make it a technological wonder that communication is able to occur at all. For these reasons, wireless products of yesteryear were prone to interference and questionable reliability, and often had to be overengineered.

Today, new methods and protocols for handling wireless communication, such as digital transmission, have been developed. These methodologies are able to facilitate the increasing demand on the limited available spectrum. The net result is that even with the greater demands placed on a limited resource, the amount of communication possible keeps increasing along with its dependability. As wireless communication becomes more commonplace, the industry as a whole is seeing the cost of related products declining compared to the immense value provided.

Looking to 2011 and Beyond


Security-industry intelligence is increasing across the board. Networked devices, video monitoring, multisensor endpoints, database access and analysis, and more are making the future a reality. Because of clients’ increasing expectations, needs and demands, many existing security systems will need upgrades, an area in which wireless products excel.

Wireless networks are becoming smarter and figure to become invaluable for intrusion and access control systems. Industry influencers believe the continued integration of wireless and wired systems is going to be facilitated by the emergence of IP connectivity and intelligent communication with existing panel infrastructure.

The move towards an IP-based system is well under way. The current economic recovery may well speed the transition along and bring about change faster than if the recession never happened. It is very likely that we could be looking at a new industry in the 2013 timeframe.

The changes in the security industry aren’t confined to wireless. Security distributors, dealers/installers and end users are all evolving along with the new realities of business. This evolution is creating opportunities for more point-to-point wireless problem-solving solutions, wireless component integration into existing networks, and complete, holistic wireless systems.

Without question 2009 shook up the way we look at business. This year has been and, going forward, will continue to be about the implementation of strategies and execution of streamlined business practices. These include an examination of the products sold and a close look at how they are applied in the field.

Thriving security integrators must take note of the changing customer requirements. Commercial wireless solutions, with their industry acceptance and market alignment, open up new revenue opportunities while providing benefits to the integrator, dealer and end user. Commercial wireless intrusion and access control truly are ready for primetime.
