Wired VS. Wireless Home Security Systems


Technology is constantly changing.  If you just look at the transformation over the past 20 years it is easy to see how electronics and technology has evolved.  Just a couple of decades ago cell phones were the size of bricks and renting a movie meant…inevitably, rewinding it.  As a custom home security company, Knight Security Systems has seen the drastic changes in our industry as well.

Security Systems, the ways in which they communicate, and the devices that help protect you have all changed drastically in the past 10 years.  One of the major changes to home security systems is wireless devices.  With the change, many homeowners have questions about the relatively new home security feature.

One of the most common questions we are asked by property owners is “Which is Better: Wired or Wireless Home Security Systems?”  While there are similarities and differences, every home might have a particular area where a wired device might work better than a wireless device and vice versa.

In this post, we’ll take a look at both systems and where these devices work best, but first let’s take a look at the key components of any traditional security system.

Every Home Security System, whether wired or wireless are comprised of four key components.  The first component is the keypad.  This is the part of the security system that homeowners interact with every day.  The security keypad is connected (hard-wired) to a power supply, as well as to the second component of the security system, the control panel.  The control panel is the “brains” of your security system.  This is where your security system’s detection devices are wired to and ultimately connected and managed. Typical panels are located in utility closets or access rooms and are wall mounted.  In the case of all-in-one systems, the control panel is built into the keypad to provide an easy to use system.  The third part of the security system is the communicator (process).  This is the way in which your security system communicates with the Central Monitoring Station.  With the advances in technology, there are now more than one way for your security system to communicate with the outside world.  Three of the most common routes of communication are through your phone line, through the internet, or through a cellular communicator.  The fourth and final component of a security system are the sensors and devices.  The devices can include; door contacts, window contacts, glass break detectors, motion detectors, smoke detectors, etc.  These devices are in constant communication with the control panel and if they are triggered, the control panel and keypad react accordingly.

The way in which these devices communicate with the control panel(4th key component) is the fundamental difference between a wired and wireless security system.  A wireless device relies on communicating through a secure and proprietary radio frequency.  A wired device communicates to the control panel through a series of wires that run through walls, ceilings, and floors.  Another difference between a wired and wireless device is the source of power.  Wireless devices receive power from Lithium batteries that are in each individual unit, while wired devices receive power through the control panel’s power supply.

So when our clients ask us “What’s better: Wireless Home Security Systems or Wired Security Systems?”  We usually explain to them that outside of all-in-one security systems, there is no such thing as a “wireless security system.”  The first three components of the security system, the keypad, control panel, and communicator are the same regardless of which system you choose.  The only difference are the devices!  While there are pros and cons of both wired and wireless devices, Knight Security does not hold one device “superior to the other”.  As a custom home security company, we design and install many security systems that have both wired and wireless devices encompassed in it.  There might be a location in your home where a wired device would simply not work due to complex wiring.  There also might be a location in your home where you would rather have a smaller, less obvious, wired device.

No matter which type of device or security system you wish to install, Knight Security will be there to provide you with the best information to help you make the right decision! Contact our team today for timely services in New York and Connecticut.
