Ajax Security Systems Cairns
Since 2020, more than 16,900 homes across the Cairns region were broken into.
Parts of the city are recording break-in rates more than five times the Queensland average. A monitored Ajax wireless security system, professionally installed by Southern Cross Electrics & Air Conditioning, can help protect your family, deter opportunistic entry, and often pay for itself through contents insurance savings.

The crime reality in Cairns
This isn’t a sales pitch. It’s the local data, and it’s why so many of our neighbours are asking about monitored alarms right now.
One line you’ll remember: In 2022, more than 3,900 homes across the Cairns region were broken into.
Supporting numbers:
- Cairns North recorded a break-in rate more than 488 percent above the Queensland average.
- Cairns City came in even higher, sitting around 520 percent above the state average.
The pattern our team sees most often is opportunistic entry through an unlocked door, an open window, or a poorly lit side access — exactly the gaps a monitored Ajax system is designed to close.
Most of those homes had never thought they’d be a target. If you’ve been thinking about a security system, talking to us costs nothing and protects everything.
No obligation. We’ll visit your home and design a system tailored to your family — at no cost.
Why Ajax Security is right for FNQ homes
In plain English: Ajax is a sleek, wireless security system you control from your phone. Photo verification means you see what’s happening at home — not just a generic alert. No cables, no tradie mess, batteries that last years, and a system built to handle Far North Queensland heat, humidity and storm seasons.
Every Ajax device is wireless, finished cleanly, and engineered in Europe. For heritage homes and Queenslanders, the no-cable install matters — there’s no chasing through your roof, no damaged cornices, no messy retrofit.
In short: a system you set once and forget about, until the moment you really need it.
We install and support Ajax systems across Cairns, the Northern Beaches, Smithfield, Redlynch, Edmonton and surrounding suburbs.
What it means for your household:
- See what’s happening, not just a notification. Photo verification sends images of an event to your phone in seconds, so you know whether it’s a real intruder or the cat.
- Stays on through a blackout. The hub keeps running on backup battery — through power outages and the cyclone-season events we get in FNQ.
- Built for tropical conditions. Outdoor sensors are rated for humidity, heat and storms, so they keep working when cheaper systems start misbehaving.
- Pets stay welcome. Motion sensors ignore cats, dogs and visiting possums, so you can arm the system without locking the dog out.
- Long battery life. Most sensors run for around seven years on a single set of batteries — no yearly ladder-climbing.
- Covers the whole property. Wireless range handles large blocks, sheds and detached structures without extra hardware.
- Made in Europe, not China. NDAA-compliant, strict European security standards, and no concerns about data sovereignty.

The Ajax range: built for FNQ homes
Every Ajax system is built from three core categories — sensors that detect, cameras that verify, and sirens that deter. Here’s what each one does for your home, and why they matter in Far North Queensland.
Sensors
Detection that knows the difference
- MotionProtect — indoor motion sensor that detects people moving through your home while ignoring pets up to 20 kilograms. No false alarms from the dog walking around at night, and no more getting out of bed to check a generic notification.
- MotionCam — the motion sensor with a built-in camera. It detects movement and sends a photo series to your phone within seconds, so you see what’s happening — not just a generic alert. You’ll know whether it’s a real intruder or a possum on the roof before you decide what to do.
- MotionCam Outdoor — the weatherproof version for carports, patios and side gates. Gives you the same photo verification outdoors, and is rated for FNQ humidity, heat and storm seasons, so it keeps working when cheaper units start misbehaving.
- DoorProtect — a slim door and window sensor that knows the moment something opens. Runs for around seven years on a single battery, so you install it once and forget about it — perfect for renters, owners, and the upstairs windows you don’t open often.
- GlassProtect — listens for the specific frequency of breaking glass from up to nine metres away, while filtering out barking dogs, traffic, TV and storms. It catches the one event that matters and ignores the noise.
- LeaksProtect — a tiny water leak sensor that spots burst pipes, leaking washing machines or air conditioning condensate overflow before they become a flood. Pairs with an automatic water shutoff if you want one. Particularly useful for FNQ homes with upstairs bathrooms, or for holiday houses that sit empty between visits.
Cameras
See what’s happening, in real time
- MotionCam Indoor — the photo-verification sensor above also acts as a camera. Snapshots arrive in your phone within seconds of any detected movement, so you’re never left guessing whether to act.
- MotionCam Outdoor (PhOD) — outdoor photo verification plus Photo on Demand. Check on the front patio, the pool area or the side gate from your phone whenever you want — not just when an alarm triggers. The outdoor security camera setup that gives you eyes on the property without a monthly subscription.
- DoorBell — a smart video doorbell that shows you who’s at the front door from anywhere — work, the shops, on holiday. Two-way audio means you can talk to a courier or a visitor without opening the door. AI recognition tells you whether it’s a person, a vehicle or the neighbourhood cat. It keeps working even when your Wi-Fi drops.
Alarms and sirens
When something does happen
- HomeSiren — an indoor siren adjustable from around 80 to 98 decibels, so it can be loud enough to scare off an intruder without being overkill for a small unit. Doubles as a door chime when you arm or disarm, so you get a friendly confirmation sound as part of everyday use.
- StreetSiren — a loud outdoor siren with a built-in LED flash, built for FNQ conditions. Humidity, heat and storms don’t phase it. Most opportunistic intruders leave the moment this goes off — the deterrent effect does most of the work.
- Hub backup battery — the brain of the system keeps running through blackouts, with some hub models giving you more than 60 hours of backup. Means your home alarm system stays on through cyclone-season power outages, not just everyday ones.
Frequently Asked Questions from Cairns homeowners
Will my pets set it off?
No. Ajax motion sensors are pet-immune — small animals up to about 20 kilograms indoors and roughly 80 centimetres tall outdoors are ignored. Dogs, cats and visiting possums don’t trigger the alarm.
What happens during a cyclone or power outage?
The Ajax hub has a built-in backup battery that keeps the system running through blackouts. Some hub models give you more than 60 hours of backup. The sensors themselves run on long-life batteries, so even a multi-day outage doesn’t stop the system working.
How do I claim an insurance discount?
Call your insurer and ask what discount applies for a professionally installed, monitored alarm. We provide an install certificate on completion that you forward to your insurer — most will apply the discount at your next renewal.
Do I need a paid monitoring subscription?
No. Many homeowners use the Ajax app on their phone and self-monitor. Paid professional monitoring is available if you’d prefer a security company to respond on your behalf, but it’s optional, not required.
How long does installation take?
A typical Cairns home is installed in a single day. Larger properties or systems with more devices can take a little longer. We’ll give you a clear time estimate at the quote stage.
What if I move house, can I take the system with me?
Yes. Ajax is fully wireless and designed to move with you. We can either reinstall at your new home or update the system layout to suit the new property.
Is Ajax approved for use in Australia?
Yes. Ajax meets European security standards and is fully approved for residential and commercial installation in Australia. SCEAC is a preferred installer.
How long do the batteries really last?
Most Ajax sensors run for around seven years on a single set of standard batteries. The hub itself has a rechargeable backup battery. You’ll get a notification well before any battery needs replacing.
