If you want a modern alarm that actually stops trouble at the boundary, not just at the front door, Ajax is built for that job. It is a polished, wireless system that suits Queenslanders, canal-front homes, apartments, and small businesses across South-East Queensland.
At Mr Secured, we install Ajax every week because it is reliable, fast to alert, and simple to use. No fluff, no lock-in. You get an encrypted, battery-powered ecosystem with phone control, optional monitoring, and devices that look good and last.
Here is how Ajax works in plain English, why we specify it, and what to consider for your property in Brisbane and beyond.
What an Ajax system is
Ajax is a European Grade 2 wireless alarm platform. Think of it as a smart hub and a set of sensors that talk securely over long range. The hub sits quietly near your modem or in a secure spot. Sensors go on doors, windows, ceilings, walls, and fence-lines. When something trips, Ajax sends instant alerts to your phone and can show a short photo burst for verification.
Key building blocks we typically use:
Hub 2 Plus, the brain, with Ethernet, Wi-Fi, and dual-SIM 4G for failover.
MotionCam, an indoor motion sensor that sends a five-frame photo sequence on alarm
DoorProtect, a slim wireless contact for doors and windows
Outdoor PIRs such as MotionProtect Outdoor and DualCurtain Outdoor for fence-lines, driveways, and side returns
Everything is wireless and encrypted. Most sensors run for years on batteries, so we install cleanly with no wall chasing.
How Ajax works day to day
The Hub 2 Plus talks to sensors using Ajax Jeweller radio, an encrypted, long-range signal rated up to 2,000 metres in open air. In practice across Brisbane homes, that means stable coverage through typical walls, double-brick, and many Queenslander timber frames. The app is your control centre. Arm at night, disarm when you get home, check history, view photo verifications, and share access with family or staff.
What you will notice:
Photo verification in seconds on MotionCam, so you know if it is a person, not a curtain
Pet immunity on compatible motion sensors, typically up to 20 kg, to cut false alarms
Anti-jamming and tamper protection built in
Backup battery in the hub for power outages
Seamless failover between Ethernet or Wi-Fi and dual 4G SIMs if the internet drops
Self-monitored vs professionally monitored
Most households self-monitor through the Ajax app. You get push alerts, event logs, and photo bursts. For many families and small offices, this is enough.
Professional monitoring adds a control room that watches your system 24/7 and escalates events. We can connect Ajax to an Australian monitoring station on request. Typical fees in our area are about $25 to $35 per month. Choose self-monitoring if you are comfortable handling alerts. Choose professional monitoring if you want a third party to call you and dispatch help when you are offline or travelling. No hard sell either way.
Why we recommend Ajax in SEQ
Brisbane homes and small businesses benefit from fast detection and clean installs. Ajax does both. It is also flexible enough for tricky layouts.
Common local use-cases:
Queenslanders and character homes: Wireless sensors avoid chasing plaster, VJ walls, and ornate trims. DoorProtect and MotionCam cover typical entry paths without spoiling the look.
Acreage fence-lines: DualCurtain Outdoor and MotionProtect Outdoor create early-warning perimeters on long driveways, paddocks, and sheds. Jeweller radio’s long range and hub 4G backup work well where fixed internet is average.
Water-front properties: Outdoor PIRs filter sun, breeze, and water glare, and StreetSiren adds instant, audible deterrence. MotionCam photo bursts confirm activity on pontoons and side paths.
If you want visual evidence at the moment something happens, MotionCam delivers a short clip-like photo sequence to your phone in under 10 seconds. That context is the difference between ignoring a ping and acting fast.
Core devices explained
Hub 2 Plus: The control panel with Ethernet, Wi-Fi, dual-SIM 4G, and backup battery. It manages up to 200 devices and handles failover automatically.
MotionCam and MotionCam Outdoor: Motion sensors with onboard cameras for photo verification. Great for hallways, living zones, and outdoor approaches.
DoorProtect: Discrete magnetic contacts for doors and windows, including sliders and French doors common in Brisbane.
Outdoor PIRs: MotionProtect Outdoor uses dual-sensor logic to reduce false triggers from pets, wind, and heat shimmer. DualCurtain Outdoor forms two long, tight curtains to protect fence-lines, balconies, and side returns.
We also add HomeSiren or StreetSiren for instant noise, KeyPad or KeyPad TouchScreen near entries, and FireProtect smoke alarms where required by Queensland legislation.
If you are looking at a full security stack, we also supply CCTV that integrates with alarms. For examples and pricing on cameras, see our page for home security cameras in Brisbane. We also handle smoke detector upgrades and can advise on Ajax FireProtect for Brisbane smoke alarm installation.
Can Ajax run without internet?
Yes. Local alarm functions continue without internet, and the hub’s backup battery keeps the system running during an outage. You will still get sirens and local triggers. For phone alerts when the NBN is down, Hub 2 Plus can fail over to its dual 4G SIMs if a cellular plan is inserted and configured. If all connections are offline, remote notifications will pause until connectivity returns.
Can you install Ajax yourself?
Technically, many Ajax devices are DIY friendly. In practice, correct placement and configuration make or break a system. Outdoor PIRs need careful height, angle, and zone tuning to keep alerts accurate in Brisbane heat, storms, and busy streets. We design, install, set up the app, train your family or team, and provide ongoing phone support. Most homes are done in a single visit with a clean finish and no exposed cabling.
Who owns Ajax?
