Welcome to Global Detection Systems

To make sure that your property is safe and secure all year round call upon Global Detection Systems. With a wealth of experience installing high quality security systems of all sizes we can make sure that your premises are secure at all times.

If you want to have a security system installed to protect your property and loved ones then you need to be careful you don’t go down costly, inefficient dead ends that waste nothing but your time and money.

You see, most other solutions that claim to be able to help you install a high-quality security system do not have the 20+ years of experience we have had installing these quality systems into your home or office. Many other local installation companies cannot rely on this background experience and having been only half way up the mountain they cannot see all the problems that may occur with your installation.

And that’s why we’re different. We’re the “mountaineer” who has reached the summit of the mountain. We have seen it all, the good, the bad and the ugly in our industry. We want to ensure that when you receive specialist advice and invest in a security system you do not make these mistakes:


  • You don’t pay over the odds
  • Choose an unreliable product
  • Be taken advantage of
  • Have unprofessional installers make the situation worse

I was so impressed with Global Detection Systems. The telephone, email and face-to-face communication was efficient, courteous and friendly and all my queries were clearly answered. The installation was completed in a timely fashion, with patience and good humour throughout. I highly recommend this company.
