Intruder Alarms

Protecting what matters most

Imagine returning home to find your sanctuary violated—or opening your business to discover a break-in overnight. At ISG, we believe peace of mind shouldn’t be a luxury. It should be a guarantee.

As an SSAIB-accredited installer, we deliver intelligent, high-performance intruder alarm systems tailored to your property, backed by trusted names like Orisec, Pyronix and Ajax. Whether you need protection for your home, office, or commercial premises, our solutions are designed to deter, detect, and defend—around the clock.

Perimeter Detection
Secure all entry points with motion detectors, door/window contacts, and shock sensors for early intrusion alerts.

External Detection
Keep unwanted visitors off your property before they even reach the building with outdoor motion sensors and beams.

Smart Control
Arm, disarm, and monitor your system from anywhere using your smartphone. Receive real-time alerts and check system status on the go.

What Our Clients Say…

“ISG has been great, took his time to assess my place, listened and made suggestion on the appropriate products. On the installation day, he took his time with the whole process, answered all my questions and did a really good job. Integrated Security Group is highly recommended”

Rita L, Residential Client

“ISG had previously done installations in several properties used in one of the businesses I am involved in. The quality and thoroughness of the work carried out meant I had no hesitation in using ISG again when I recently moved house and needed a new alarm and CCTV system. I'd highly recommend ISG for both domestic and commercial security systems.”
