What to look for in an intruder alarm

Like thousands of other responsible homeowners, you’ve made the decision to install an intruder alarm. It’s a great choice – studies have shown that intruder alarms protect valuables and family members by deterring would-be criminals. However, there’s a wide variety of alarms available, with different features and price tags. In this post, we explain what to look for when choosing between intruder alarms.

Wireless vs. Hardwired

There are two basic types of intruder alarm, with pros and cons to both. Wireless systems are quicker to set up. They use radio signals to communicate with sensors, are powered by batteries and are portable as a result. Hardwired systems require more work, since wires need to be hidden behind the wall. However, they’re far more durable and don’t need as much maintenance as their battery-powered cousins.


The best intruder alarm systems are far more than a ringing bell. Although in days gone by this was enough to alert neighbours and scare off intruders, nowadays its best to use a two-pronged response. Our new systems incorporate remote signalling devices which contact a monitoring station should an intruder attempt to break into your home. The monitor can then alert police, making sure that help is on the way.

Choose Detectors

There are a variety of detectors available, all of which perform important functions:

  • Motion detectors will detect any movement inside the house after you’ve set the alarm. Furthermore, our new models are so sophisticated that they can tell the difference between intruders and pets, preventing false triggers of the system.
  • Door and window detectors will trigger when someone attempts to gain entry through a closed entrance. Depending on where you choose to have them installed, they can detect when a window, door, cupboard or even a drawer is opened. This versatility makes them a popular choice.
  • Shock detectors monitor windows and doors for vibrations. Rather than waiting until a window or door is forced open, these detectors will register if someone begins to even try to gain entry.

High Decibels

Unfortunately, in the past an ordinary burglar alarm wasn’t always effective at deterring thieves. That isn’t the case with our modern systems. If an intruder breaks into your home a siren will sound at an ear-splitting volume of 115 decibels! It’s guaranteed to alert everyone in the neighbourhood and frighten off any would-be burglars.

Extras included?

When purchasing a new intruder alarm, it’s a good idea to check out what extra features are included. Several models come with key fobs that allow you to remotely set your alarm. Additionally, they can be used to trigger panic alarms, switch lights on and off, and close gates or garage doors.

Some systems can also be set to monitor the perimeter of your property. Using a range of shock and contact detectors, these systems can prevent intruders from ever getting close to your home.

Whichever type of intruder alarm you decide is best for you, make sure you understand how to use it. Leicester Police have issued the following advice for anyone thinking of installing an intruder alarm:

“Make sure that the company you choose offers a short training session to show you how the system works. British Standards requires that there is a ‘hand over’ period in which the alarm company makes the user familiar with the system’s operation and also that they can offer a back-up service for routine maintenance or faults to your system.”
