How Does Wireless Home Security Work?


The average new home alarm system is either partially or completely wireless. The primary benefit of going wireless is that it is possible to install a complete system without any need for major construction. However, consumers need to be careful about what constitutes a completely or partially wireless system. Different providers define things in different ways.

To understand how it all works, it is first important to understand the three primary components of home security:

  • Detection – Regardless of whether it is wired or wireless, a security system must include instruments to detect when a home has been breached. This includes window sensors, door sensors, motion sensors and, in some cases, video cameras.
  • Trigger – A second component recognizes the trigger event that sets off the alarm. For example, once a sensor detects intrusion it must send a signal to a control panel capable of interpreting that signal and triggering an alarm. The central control panel affixed near the front door is usually the trigger component.
  • Communication – In a monitored home security system, the control unit communicates with a remote monitoring center. The control panel communicates the trigger alarm and the monitoring company communicates with the homeowner and local authorities.

Now that you know the three primary components of the security system, let’s talk about wired versus wireless. If you have a system more than seven or eight years old, it is likely fully or partially wired. Most modern systems are wireless.

How It All Works

A fully wired system connects detection components, control units and the monitoring center using hardwiring. Internal wiring in the house connects sensors with the control panel; telephone or cable connects the control panel to the monitoring station. Everything in the home is powered by a direct connection to the home’s electrical system.

A wireless system removes the need for any kind of wiring. Detection components are connected to the control panel using FM or UHF radio waves; the control panel is connected to the monitoring station using cellular signals, the same way your cell phone operates. Everything within the home is powered using lithium-ion batteries.

In terms of function, there is little difference between a wired and wireless system. Both kinds of systems utilize detection, trigger, and communication to protect property. Nonetheless, the wireless system offers a number of distinct advantages:

  • Constant Communication – With the wireless system, there are no telephone lines to be cut by a burglar. That means the control panel is always in constant communication with the monitoring center.
  • Power Outages – The wireless home security system works even during power outages because it operates on batteries. As long as batteries are changed according to the provider’s set schedule, homeowners need not worry about systems going out.
  • Construction – As we already mentioned, a wireless system can be installed without the need for major construction in the home. With wireless systems, there is no cutting into walls, adding circuits to fuse panels or having to run new wiring to support a system.
  • Scalability – A wireless system also allows for scalability. New components can be added or taken away as the homeowner sees fit, with very little effort.
