A wireless alarm is perfect for new-builds as well as period properties

You are not allowed to carry out excessive building works with a period property however the lack of hard-wiring with a wireless alarm means you’re not breaking any building regulations.

On new build sites for both residential and commercial properties, there are deadlines that need to be met. Wireless alarms can be installed in significantly less time meaning we won’t get in the way of your busy schedule.

Control your smart alarm system on the go

Forgetting to set your system is a thing of the past with our range of smart alarms. Via a burglar alarm app on your phone, you can arm or disarm your system from anywhere in the world.

Alerts can also be set up to let you know if someone has armed the system themselves during your absence. If you would like to know more about this, please get in touch.


Control your intruder alarm from wherever you are with our handy app

Smartphone enabled security systems are the biggest development that we have seen in our industry for many years. Gone are the days where you had to return to your property to set your alarm. The app allows you to activate and deactivate your alarm from anywhere as well as set alarm zones and view alerts.

No matter the challenge, we will have the answer

We’re qualified and motivated installers who seek to ensure the worst doesn’t happen.
