Understanding wireless home security systems

If you've been considering investing in a home security system, you're probably aware that there are a variety of shapes, sizes and price ranges. The real challenge is deciding between wired and wireless alarm systems.

Wireless or wired home security system?

The truth is that a wired or wireless home security can be monitored by a professional security company. Both can be installed as a DIY project or by a professional, although an experienced security professional, such as an ADT expert, is often recommended if you want to add sensors, remote arm and disarm features, etc.


Traditional systems can be just as effective as a wireless alarm system, but one disadvantage is that they run off electricity supplied through electrical wires.

Advantages of wired home security systems:

  • Wired systems can often accommodate several ‘zones’ of protection.
  • They are reliable.
  • The system tends to be less susceptible to radio or electrical interference.
  • They use a backup battery system during electrical interruptions.

Disadvantages of wired home security systems:

  • Wired systems can be difficult to install.
  • It can be a real challenge to hide all the wiring when installed in an existing home.
  • Once installed, it can be difficult to remove and take with you should you move.

Advantages of wireless home security systems:

  • Wireless home security systems use radio waves rather than wires or cables, to communicate between the control panel, sensors and cameras.
  • They're a great alternative for people living in older homes, condominiums or apartments.
  • Since wireless systems have their own batteries, they can be installed in locations in a home where there is no electrical access.
  • The system can be expanded as needed.
  • Wireless security systems can be connected to a phone and/or computer systems for remote monitoring.
  • Can be integrated with home automation systems, like ADT Interactive Services. 

Disadvantages of wireless home security systems:

  • Sensors will need batteries to operate, so there is a possibility that the batteries will die if they are not checked often.
  • Components need to be close to the central control panel. This can limit where some sensors are placed.



When it comes to installation, a wireless alarm system can be easier to install when compared to conventional hard-wired systems. In the traditional setup, wires must be run through the home to every entry point and motion sensor, which includes all doors and windows. Wireless home security systems tend to be easier to install, and they're portable, so in the event of a move you can easily take the system with you.

While both systems have their pros and cons, the best system is the one that fits with your family's lifestyle and needs.
