Security Alarm Systems Perth
A Malaga wholesaler rang us after their third after-hours break-in in six weeks. The alarm panel was 14 years old, the phone line had been cut, and the insurer had refused a fourth claim. Inside ten days we replaced the head unit, added perimeter protection, commissioned HD cameras over the loading dock, and connected everything to our monitored control room. No further incidents in 18 months.
That is what a properly designed security alarm system delivers. At Castle Security, founded in 1989 and fully licensed, we install security alarm systems that Perth homes and businesses rely on.

Why Security Alarm Systems In Perth Are Vital
Perth alarm systems earn their keep when something goes wrong, not when the brochure promises peace of mind. Across Western Australia we see the same patterns, opportunistic break-ins through rear sliding doors, vandalism at unmonitored commercial sites, and insurance claims declined because the alarm was decommissioned six months earlier.
A modern alarm system combines motion detectors, door contacts, smart sirens and monitored reporting so a trigger event becomes a 90-second police dispatch rather than a Monday morning phone call.
As members of the Australian Security Industry Association, we design security solutions matched to your property, not the kit on the van.

Professional Security Systems Perth
With over 30 years in the security industry we design and install alarm systems that suit a two-bedroom unit in East Victoria Park as readily as a 5000sqm warehouse in Kewdale.
Our systems combine alarm, CCTV systems, access control systems and 24/7 monitoring on a single platform, so the business owner does not carry four different apps on their phone.
We will also push back where the brief is wrong, if you ask for a basic alarm system and your site actually needs perimeter beams, we will tell you.
Our alarm systems typically include home and commercial alarm panels, CCTV systems and security cameras, motion sensors and perimeter detection, internal and external sirens, access control with smart lock options, and professional alarm monitoring with fast response.

What we offer is three decades of site experience, a dedicated professional team that includes Director Louis Thorp and long-standing installer Gordon, and quality products we actually stock at Landsdale so a failed device ships the same day.
We are fully licensed through WA Police Licensing Services, ASIAL certified, and an accredited Gallagher Security partner since 2015. Our timely response on faults averages under 24 hours metro, and we offer payment plans for alarm packages so a new alarm system does not need wait.
