Ajax builds the rare alarm system people are happy to have on the wall: design-led wireless hardware, an app that feels like it was made this decade, and an ecosystem that grows from a couple of sensors to a whole property. Our job is to be straight about where it fits in Adelaide. In timber-frame homes, townhouses and modern infill it's excellent. In solid double-brick, masonry soaks up wireless signal — so we test on site and design Ajax as a hybrid where the walls demand it, instead of selling wireless-everywhere and hoping.
The most common failure mode of a home alarm isn't technical — it's the family that stopped arming it because the keypad was a chore. Ajax's app makes arming, checking and event history genuinely easy, and a system that gets used beats a fancier one that doesn't.
Detectors, keypads, sirens, buttons and automation devices all live on the one platform, so a system can start small — entry doors and a couple of rooms — and grow as budget or circumstances change, without ripping anything out.
We install several alarm brands, which means Ajax has to earn its place on each job. Where a property suits wireless — clean walls you don't want drilled, rentals, staged budgets — it's often our first suggestion. Where it doesn't, we'll tell you that too.
Good equipment still fails when it's installed like this is Melbourne. How we put Ajax Systems systems in up here:
Adelaide's double-brick middle ring is where all-wireless kits go to sulk. We walk the property and check signal room by room before finalising a design — and where a back bedroom or rear extension sits behind too much masonry, we plan the device placement and repeaters around it, or specify a hybrid design rather than pretending.
The controller goes inside the conditioned envelope of the house — a hallway cupboard, not the garage or the western shed wall that hits oven temperatures every summer. Heat is the quiet killer of electronics in this state, and central equipment placement is a design decision we make deliberately on every job.
For Fleurieu and coastal holiday homes managed from Adelaide, we set up remote arming and sensible alert rules: arm from your phone after the cleaner leaves, get notified for the events that matter, and check in without driving down. Ajax's remote control is one of the main reasons holiday-home owners choose it.
New builds and renovated homes where nobody wants cable chases through fresh plaster. Wireless devices go up cleanly, and the finished system looks like it belongs in the house.
Because the system installs without permanent wiring, it can come with you. For renters, and for owners who know this isn't their forever home, that changes the economics of having a proper alarm at all.
Beach shacks and Hills weekenders that sit empty most of the year, secured and checkable from a phone in Adelaide — with the system growing later if the property does.
Great White Security is product-agnostic — we install and service Ajax Systems systems where they're the right fit for the site, and recommend alternatives where they're not.
