An alarm system helps reduce your chances of becoming a victim of crime

Our advanced alarm systems form the backbone of a reliable security system and help stop burglars in their tracks. We have been installing alarms for over 4 decades and have gained a great insight into the unique security challenges each industry faces on a daily basis.


Protect what matters most to you and outsmart criminals

We utilise award-winning alarm technology to protect your property, people and assets from daily security risks.

We ensure each alarm system is carefully designed and installed to perfectly suit your premises to provide you with the level of protection that you require. Each system is also installed in accordance with EN 50131 standards. This commitment to perfection is why we have installed thousands of intruder alarms over the last 40 years for customers across Surrey.

Protecting your investments and ensuring your alarm is performing at its full potential

Our pre-planned alarm maintenance visits are key to the reliability and accuracy of your alarm system. Our visits will make sure that your alarm system is performing at the highest of standards and keeping your property safe from intruders.

If you are unhappy with your current alarm provider and would like us to take it over, all we need is a little information about your current system to guarantee we can maintain it for you.


Wireless alarms a trusted and viable option for your property

The lack of hard-wiring means that our engineers can install your new alarm system much more quickly. This will result in less time on-site and less disruption to your busy schedule.

Wireless alarms can also sync and learn new detectors very easily. Perfect should you expand your property later down the line and require extra security.
