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.
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:
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.
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:
We install and support Ajax systems across Cairns, the Northern Beaches, Smithfield, Redlynch and surrounding suburbs.
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.
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.
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.
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.
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.
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.
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.
Yes. Ajax meets European security standards and is fully approved for residential and commercial installation in Australia. SCEAC is a preferred installer.
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.
