Best Alarm Systems Perth 2025 — Brands and Options Compared

Choosing an alarm system in Perth means navigating a range of brands, monitoring options, and price points. The right system for your home depends on your risk level, budget, and how you want to be alerted and protected. Here's an honest comparison of the main options available in Perth in 2025.

Monitored vs Unmonitored Alarms

An unmonitored alarm activates a siren and may send an app notification when triggered — but no one automatically calls for help. For Perth homes that are occupied most of the time, unmonitored systems provide a basic deterrent. For homes left empty for extended periods, investment properties, or anyone who wants guaranteed response, professional back-to-base monitoring is worth the $30–$60/month cost. Back-to-base monitoring means a 24/7 response centre contacts you and, if needed, emergency services when an alarm is triggered.

Major Brands Available in Perth

Bosch — The most common professional-grade alarm system brand in Perth. Bosch Solution series panels are used by most Perth security companies. Reliable, well-supported, and compatible with a wide range of sensors and accessories. Not typically available DIY — installed by licensed security companies.

Hills — Another professional-grade option widely used in Perth. The Hills Reliance system is common in commercial and residential installations. Similar to Bosch in quality and price point.

ADT — A large national monitoring company that offers both equipment and monitoring services. ADT provides end-to-end service including installation and 24/7 monitoring. Equipment quality is solid; monitoring response is their key selling point.

Swann — Retail brand available at Bunnings and Harvey Norman. Swann alarms are a DIY-accessible, budget-friendly option. Suitable for basic deterrence in lower-risk situations. Not compatible with most professional monitoring services.

Wireless vs Hardwired

Modern wireless alarm systems use encrypted radio communication between sensors and the panel, making them nearly as reliable as hardwired systems with much easier installation — no cable runs required. Hardwired systems remain the gold standard for new builds. For existing Perth homes, wireless systems are practical and professional-grade options are genuinely reliable.

Pet-Immune Sensors

If you have dogs or cats, standard PIR sensors will trigger false alarms from your pets. Pet-immune sensors (available for Bosch, Hills, and other professional systems) use dual-technology detection to distinguish between human movement and smaller animals. Specify these when booking your Perth security installer if you have pets.

Typical Installed Costs in Perth

A professionally installed alarm system in Perth typically costs $500–$1,200 for a standard residential installation (panel, keypad, 4–6 sensors, siren). More complex systems with CCTV integration, multiple zones, or larger homes cost more. Professional monitoring adds $30–$60 per month on top of the hardware cost.
