Ajax Security Systems Perth Review 2025: Are They Worth It?
Detailed Perth-focused review of Ajax wireless alarm systems – how they work, what they do better than traditional alarms, where they are strongest, and when another system might be a better fit.
Ajax has become one of the most talked‑about wireless security systems in Perth over the last few years. Homeowners and business owners love the clean modern design, powerful mobile app, and flexible wireless devices – but is it actually the right alarm system for your property?
In this 2025 Perth review, we break down how Ajax works, the real‑world pros and cons we see every week during installations, typical pricing for WA properties, and when we recommend Ajax over more traditional alarm brands.
Quick Summary: Ajax in Perth
- Best for: Existing homes, renovations, townhouses, and small businesses that want high‑end security without running new cables everywhere.
- Strengths: Long‑range encrypted wireless technology, app control, photo verification, sleek detectors, and flexible expansion.
- Limitations: Requires good internet/4G coverage and can cost slightly more up‑front than budget alarm brands.
- Our view: One of the best wireless alarm platforms available in Perth in 2025 when designed and installed properly.
What Is Ajax – And How Is It Different?
Ajax is a next‑generation wireless security system built from the ground up as a smart, app‑driven platform. Unlike many “old school” alarms that were designed decades ago and slowly upgraded, Ajax was engineered for modern homes, fast installation, and reliable wireless communication.
Key differences compared to traditional alarm systems we see across Perth include:
- Long‑range encrypted wireless: Ajax’s Jeweller radio protocol offers up to 2km wireless range in open air, with strong encryption and heartbeat monitoring between devices.
- Beautiful, modern hardware: Slimline detectors, keypads, sirens, and remote controls that actually look good in a modern Perth home or office.
- Photo verification: Motion detectors like MotionCam can send a series of photos to your phone when an alarm triggers, helping you quickly see if it’s a real intruder or a false alarm.
- Top‑tier mobile app: The Ajax app gives full control of arming, disarming, zones, notifications, automation and user codes – without clunky menus.
Ajax vs Traditional Wired Alarms
In Perth, we still install a lot of high‑quality wired systems (especially during new builds), but Ajax is often a better choice for established homes where running new cables would mean cutting walls and ceilings.
- Installation speed: Wireless installation is typically faster and less invasive, which is ideal when you are living in the property.
- Flexibility: Devices can be added, moved, or removed without rewiring the house.
- Reliability: With proper design and signal testing, Ajax is extremely reliable in standard Perth homes and businesses.
Key Ajax Features That Matter in Perth
Not every Ajax feature matters equally for every property, but these are the capabilities our Perth clients care about the most.
Pet‑Friendly Motion Detection
Ajax detectors can be configured to ignore pets up to a certain size, which is essential for Perth homes with indoor dogs. Correct sensor placement and configuration are critical – we always design layouts to minimise false alarms.
Photo Verification & Instant Alerts
When an alarm is triggered, supported detectors can send encrypted images to your phone. This lets you quickly see whether it is a genuine break‑in and decide whether to call police, a neighbour, or your monitoring centre.
Power & Internet Backup
Ajax hubs have battery backup and optional 4G communication so the alarm can keep working when the NBN drops or power is cut. For many Perth suburbs with patchy power or internet, we strongly recommend including this in the design.
Smart Automation
Ajax can integrate with smart plugs, gate controllers, and lighting. Many clients automate lights to turn on if an alarm triggers, or open gates for emergency access when required.
Ajax Alarm Pricing in Perth (2025)
Exact pricing depends on your floor plan, number of openings, and whether you connect Ajax to CCTV or monitoring. To give you a realistic starting point for 2025, these are the ranges we typically see for professionally installed Ajax systems in Perth.
| Property Type | Typical Setup | Installed Price (Approx.) |
|---|---|---|
| Small Unit / Townhouse | Hub, keypad, 4–6 door/window sensors, 1–2 motion detectors, internal siren | $1,800 – $2,400 incl. installation |
| Average Perth Home | Hub, keypad, 8–12 door/window sensors, 3–5 motion detectors, internal & external siren, app control | $2,400 – $3,500 incl. installation |
| Larger Home / Small Business | Hub, multiple keypads, 12+ sensors, photo verification, 4G backup, integration with CCTV or access control | $3,500 – $7,000+ depending on scope |
Monitoring is optional with Ajax. Some Perth clients choose self‑monitoring via the app only, while others connect to a graded monitoring centre for 24/7 response. Monitoring fees generally start around the same range as other professional alarm systems.
Pros & Cons of Ajax in Real Perth Homes
No alarm system is perfect for every property. Here is how Ajax stacks up in the real‑world installations we complete across Perth each month.
Where Ajax Shines
- Fast, low‑mess installation in existing homes and offices.
- Excellent mobile app experience for day‑to‑day use.
- Stylish detectors and sirens that blend into modern interiors.
- Strong wireless performance when properly designed and tested.
- Easy to expand with extra devices as your needs grow.
Potential Limitations
- Relies on good internet/4G coverage for full functionality.
- Slightly higher up‑front cost than entry‑level alarm systems (though similar to other premium brands).
- Wireless signal planning is critical in very large concrete or steel‑framed buildings – sometimes wired systems still make more sense.
Is Ajax Right for Your Perth Property?
Based on our experience across thousands of security installations, Ajax is an excellent fit for many – but not all – Perth properties.
Great Match For
- Established homes where you want minimal cabling and patching.
- New renovations, townhouses and duplexes needing flexible layouts.
- Professional couples and families who live on their phones.
- Perth properties that may need to expand security later.
May Not Be Ideal For
- Very remote sites with unreliable internet and mobile coverage.
- Large industrial facilities where heavy construction blocks wireless signals.
- Projects where cabling is already being installed and a high‑end wired system is more cost‑effective.
