Choosing a Wired or Wireless Alarm System

Pros and Cons of Wireless and Wired Alarm Systems

With so much advancement in technology in recent years, security companies have been able to be innovative in their product creation. However, there’s an old adage that goes along the lines of – “Don’t fix what isn’t broken” – which is why old systems are still heavily used. To be specific, we’re referring to security alarms – wireless systems represent the modern, and wired systems represent the traditional.

When it comes to installing a security alarm, there’s often a debate surrounding the best option to go for. There’s an argument for both, but experts generally say that wired systems are more reliable, so if it’s your first time you may want to go down that route. But, we’re going to cover the pros and cons of both…

Wireless Alarm System

If you want to go with a wireless system, you’re probably doing so because you want to avoid the hassle of tangled wires being visible in your property. You see, with a wireless system, you can generally install them on your own very quickly. It’s just a sensor communicating with a  console via radio signals, and the console communicating with external centres via a cellular network.

If you want to add extra sensors into the chain, then you can do so extremely easily. Moreover, another great thing about wireless systems, is that they can be controlled via a smart device, such as a mobile phone. So, you can rest assured that your property is secure even if you’re somewhere miles away.

In addition, another difference with the wireless option is that they are solely powered by batteries, rather than hooking up to your electrics. That’s wonderful if you’re worried about the power ever going out in the mains, but it’s not so good having to remember to replace the batteries.


  • No wires – easy installation
  • Easily add extra sensors to the system
  • Install sensors in hard-to-reach areas
  • Easy to relocate system to new property


  • Batteries need to be replaced
  • Signal between sensors can be interrupted
  • Bad weather can cause false alarms
  • System has risk of being hacked if you use smart devices

Wired Alarm System

Wireless alarm systems have been around for many, many years, and that’s because they’re so effective at keeping properties secure. Although you need to get a wired system professionally installed so it’s fully immersed in your property, it’s still much cheaper than its wireless counterpart.

Furthermore, wired systems join onto your power and landline, so that it connects directly to an external centre. That means you won’t have any worry of the signal being disrupted or the connection being halted by bad weather. Plus, another difference between them is how the system is powered.

Rather than using batteries that need to be replaced, a wired system utilizes electricity, which means you’ll be connected 24/7. It doesn’t automatically come with sensors etc. but most wired systems offer the capability to add them. So, you could have a permanent alarm system with the addition of motion sensors, CCTV cameras and motion sensors if you wish.


  • Permanently installed so more reliability
  • Less expensive
  • Can’t be tampered with remotely
  • Always connected as you’re using the electric mains


  • Stop working if there’s a power outage
  • Criminals can cut through power lines
  • Don’t come equipped with extra features such as sensors
