Choosing the right home security system can be a daunting task, especially when faced with the decision of selecting a wired or wireless setup. Both types offer unique advantages that cater to different needs, and homeowners must evaluate which is best suited for their specific circumstances.

Households without home security systems are three times more likely to be robbed, according to a study by Consumer Advocate. When burglars are scouting, they are discouraged by signs of installed security systems and are more likely to attempt to enter a house that is unprotected.

Another study by the Rutgers University School of Criminal Justice examined crime statistics gathered over a four-year period by the Newark Police Department and discovered that the number of burglaries in Newark decreased as more security systems were put in place. According to the study's findings, 60% of would-be burglars are discouraged by alarms, and the majority will first try to see if an alarm is installed.

When considering a home security system, there are multiple things to consider, but one of the key elements is whether the sensors and detectors will be installed in a hardwired or wireless manner. Turns out, there are various pros and cons of wired or wireless home security systems.

Wired Home Security Systems.

Wired home alarm systems are security setups that physically connect sensors, detectors, and control panels through wiring. These systems can integrate traditional door and window sensors, motion detectors, and even security cameras as key components.

Wired security systems are often preferred for larger homes, complex architectures, or environments with numerous interference-causing elements. They also offer increased reliability and security, making them ideal for safeguarding high-value possession


  • Robust Connectivity: Immune to wireless signal interference.
  • Data Security: Enhanced as information stays within the home.
  • Lower Maintenance: Fewer components to replace over time.
  • Sleek Installation: Discreet appearance once all components are in place.


  • Installation: Requires professional expertise.
  • Higher Initial Cost: Due to professional setup.
  • Limited Flexibility: May pose installation challenges in specific home areas.
  • Portability Issues: Cannot be easily transferred to a new residence.

Wireless Home Security System

Wireless home alarm systems leverage radio frequency technology for communication between sensors and control panels. The market offers a plethora of wireless systems, each using distinct frequencies, resulting in varied performance across different settings.

Wireless systems offer unparalleled flexibility, making them ideal for those who rent or frequently move. They're also perfect for older homes where wiring might be impractical or invasive.


  • Ease of Installation: Often DIY-friendly; if professional help is needed, the process is expedited.
  • Cost-Efficient: Reduced installation and setup expenses.
  • Flexibility: Convenient to move or replace on doors; most units utilize screws or adhesive tape.
  • Portability: Ideal for renters; can be uninstalled and re-established in new residences.


  • Interference Vulnerability: Reliant on wireless networks, which can be prone to interference.
  • Maintenance Needs: Battery-operated components require regular replacements, sometimes annually.
  • System Exclusivity: Sensors are typically proprietary. Switching systems might mean changing out all sensors, unlike with wired systems.
  • Visibility: Due to internal components like batteries, sensors might be more conspicuous when installed.

Wired vs. Wireless Home Security Systems at a Glance

Low material cost, high installation cost
High material cost, low (or no) installation cost
Ease of Installation
Often requires professional installation
Very common for DIY
Requires control panel support for future expansion
Easy to add add'l devices without expansion hardware
Highly reliable
Susceptible to interference
Low maintenance and convenient once installed
Requires regular maintenance and is more visible in home

Wired vs. Wireless Home Security Systems: Affordability

In the realm of affordability, particularly over the system's lifespan, wired security systems take the lead. While their upfront installation costs might be higher, they tend to have lower maintenance expenses throughout the system's life. If you intend to reside in the same home for a significant period (typically 5 years or more), a wired system emerges as the more cost-effective choice.

Wireless systems come with electronics embedded in the sensors and require batteries that need periodic replacement. This means not only do you bear the initial costs of the sensors and detectors, but you also incur the recurring expenses of battery replacements.

Wired vs. Wireless Home Security Systems: Ease of Installation

The installation of these systems can play a large factor in the selection process, but the wireless security systems are, hands down, easier to install. Most homeowners are able to complete the installation themselves in the afternoon. Even if you select professional installation of a wireless security system, they will be able to complete the process far quicker than a wired solution.

Wired security systems have a more complex installation process, from concealing the wires in the wall, finding a way to get them to the attic or crawlspace, and generally getting them placed in the home in the best way possible. This makes wired systems far more complex to install, which is why it's best left to the professionals.

Winner: Wireless Security Systems

Wired vs. Wireless Home Security Systems: Scalability

Many times homeowners find that they want to add sensors or devices to their systems after the installation was completed. Maybe there was some remodeling done, or an addition added, and the needs of the property have changed.

When this occurs, expanding a wired system might simply involve having the professional installation company return to add another sensor, provided there's space on the control panel. If not, they may need to install an expansion board before adding the additional sensor.

When it comes to a wireless system, it's often far easier as you can just purchase, program, and mount the additional sensor. This ease of adding additional sensors makes the wireless system a clear winner when it comes to scalability.

Winner: Wireless Security Systems

Wired vs. Wireless Home Security Systems: Reliability

Both wired and wireless home alarm systems can provide a high level of security when installed correctly. As the wireless systems use radio waves to communicate back to the main control panel, this can be susceptible to interference, sometimes from things that happen after the installation is completed.

A failing motor in the HVAC system can produce electromagnetic interference, potentially disrupting the proper reception of wireless signals. Because wired systems connect the sensor and control panel directly through a wire, they tend to operate more reliably.

Wired vs. Wireless Home Security Systems: Convenience

Security systems not only enhance your home's safety but also offer convenience. Imagine the peace of mind from knowing your home is protected while on vacation, allowing you to relax without concern.

Both wired and wireless security systems use a control panel to communicate with the monitoring service. This panel lets you view your system's status, arm and disarm it, and receive alert notifications, all directly from your phone.

While both options are equally convenient in terms of usage, wired systems have an edge in overall convenience due to their lower maintenance, giving you one less thing to concern yourself with.

Bottom Line: Which Security System Is Best for Your Home?

Ultimately, no one-size-fits-all solution exists for every home or homeowner. By researching various options and consulting with professional installation companies, you can find the ideal security system for your needs.

Wired systems offer superior signal reliability and less maintenance, albeit at a higher cost. On the other hand, wireless systems can be self-installed, are more portable, but may face interference and demand more upkeep.

Taking time to think about what your needs are, as well as reaching out to companies like ADT or Vivint can help you to decide which system is best to protect your family and your home.
