Wired vs Wireless Home Alarm Systems

One of the best ways to deter burglars from breaking into your home is to install an alarm system. These come with a variety of functions but one of the biggest choices you will need to make is whether to go with a wired or wireless alarm. Here are the pros and cons of each.

Wired system


  • It is often argued that wired alarms are more reliable, and while that may not be true anymore due to modern technology, wired alarms are still more difficult for burglars to shut down than wireless alarms.
  • Due to electromagnetic interference not being an issue, you’re much less likely to receive false alarms with a wired alarm rather than a wireless one.
  • The wired alarm is often connected to the home phone line but these days wired alarms also have their own wireless connectivity enabling the authorities or yourself to be contacted even if the phone line is cut.
  • Wired systems often require little to no maintenance, unlike wireless systems.


  • The wires will need concealing, which can mean more work and more expense from the installers.
  • These wires can then get in the way if your home requires renovations.
  • If you ever choose to upgrade or add to your security system, this will inevitably require more drilling and wires to be hidden.
  • Wired alarms are usually connected to the home phone line which can be cut, not to mention that many homes don’t have a land-line anymore.  

Wireless systems


  • These are easier and cheaper to install than wired alarms as there’s no need to drill through walls and floors to hide wires. Additionally, because it takes less time, you pay less for labour.
  • Wireless alarms have been used for more than 10 years and they now work better than ever. The number of false alarms has been reduced and the alarms are now more reliable.
  • The sensors of a wireless system are usually battery powered, meaning that they will still work if the power is cut or during a blackout.
  • Wireless alarms are portable, so when you sell your home and move, your alarm can come with you.
  • Due to the simple nature of the wireless alarm, it is much easier to upgrade this type of alarm. It also won’t get in the way if you do any renovations to your home.


  • Similar to internet connections, wireless alarms can be disrupted by interference. This can mean that the alarm doesn’t work or it goes off at unpredictable times. Electrical interference from power lines, baby monitors, televisions and microwave ovens can cause wireless interference issues.
  • You need to remember to replace the batteries in the sensors regularly to keep the alarm system working properly.
  • Wireless systems can be hacked into, just like your wireless internet connection, but with much more serious consequences. The alarm can be shut down or made to go off to replicate false alarms from a distance of 10 feet from your home, which means a burglar can simply shut off your alarm or jam the signal before they enter your home.

Whether you go for a wired and wireless home alarm system will depend on how you wish to use it and your house, but ultimately both are reliable so the choice really is yours. For more information, contact a company like Pro-Tect Security Management.
