Ajax Alarm Systems
Perth

Our installed Ajax packages start from $1,280 for an apartment system, with larger home packages at $1,460 and $1,960. Extra detectors, sirens, keypads and key fobs can be added to any package at published supplied-and-installed prices, for example a door sensor at $230 or a motion detector at $190. Upgrading to the Wi-Fi Hub 2 Plus is $150 extra. Prices are for a standard Perth metro home. A wireless Ajax system can usually be quoted without a site visit; wired Superior systems and upgrades of existing alarms get a free site visit first, and other Ajax devices and commercial sites are quoted.

No. Ajax works on its own, with alerts straight to your phone. If you'd rather have a person responding around the clock, it can also be connected to a professional monitoring centre. We'll talk it through at the assessment.

Yes. The alarm continues operating locally if the internet connection drops, including responding to detectors and activating a siren where configured. For app control and notifications it needs a connection: Hub 2 and Hub 2 Plus both have two SIM slots, so a SIM card with a data plan keeps you connected when the internet is down, and Hub 2 Plus can also use Wi-Fi as well as Ethernet.

Yes. With a fully wireless Ajax Baseline system, most devices unclip from their mounts and go back up at the new place. We can do the reinstall too.

Absolutely. Because the Baseline line is fully wireless and uses mounting adhesive or small screws, installation leaves minimal marks. It's one of the most landlord and tenant-friendly security systems available.

Ajax MotionProtect detectors have pet immunity, designed to ignore animals up to 20 kg and under 50 cm tall. A bigger dog, or a pet that climbs onto furniture, can still be picked up, so where each detector goes matters, and that is part of the install.

Ajax rates DoorProtect at up to 7 years and MotionProtect at up to 5 years on their pre-installed batteries. Real life depends on settings and how often a detector is triggered. The Ajax app shows every device's battery level as a percentage, so you can see which one needs changing.

The hub has a backup battery, which Ajax rates at up to 15 hours when running on a SIM card alone. The detectors run on their own batteries, so they keep working without mains power.

No system is immune to everything, but Ajax is built to resist interference and tampering. Data between the hub and devices is protected by block encryption with a dynamic key, the radio uses frequency hopping, and you are notified if the system detects jamming or loses connection with a device. The hub also raises a tamper alarm if it is removed from its mount.

Yes. The administrator can invite other users and set each person's rights. Hub 2 supports up to 50 users and Hub 2 Plus up to 200. On a recent Armadale job, the client and relatives all have the Ajax app on their phones.

Yes. Ajax supports its own cameras and integrates with Dahua and Hikvision cameras and recorders, as well as other cameras that support RTSP, so cameras can sit alongside the alarm in the same app.

Not for the alarm itself: the Ajax app has no subscription. A monitoring centre, if you choose one, charges its own monthly fee. If the hub uses a SIM card as a backup connection, that SIM needs its own data plan.

Not from Ajax directly. Ajax has no shop of its own in Australia and supplies the market through trade distributors, who sell to accredited installers and the security trade rather than to the public. The distributors require a trade account, general electronics retailers do not carry the brand, and a small number of specialist security retailers interstate sell some Ajax hardware online. For a working system rather than a box of parts, you buy it from an Ajax authorised installer. Dextel is an Ajax authorised installer in Perth, certified for both the Superior and Baseline lines, and supplies and installs at published prices.

The Superior line, no. Adding Superior equipment to a system requires an installer holding current Superior accreditation from Ajax, so owning the device is not enough to commission it. The Baseline line is wireless and designed to go in cleanly, but the hardware is only part of it: where each detector goes, how the zones and sensitivities are set and how the hub is commissioned are what decide whether the alarm catches an intruder or cries wolf, and a self-installed system leaves the warranty claim with you.

Workmanship on anything I supply and install is warranted for as long as that item's own manufacturer warranty runs, never under 12 months and never over 5 years, and equipment I supply and install carries a 12-month on-site service warranty. After the 12 months, whatever is left of the manufacturer warranty is passed on to you, and you contact me rather than the manufacturer: I assess it and make the claim with the supplier on your behalf. Flat batteries, tampering and faults in equipment someone else supplied sit outside it, and your rights under the Australian Consumer Law apply on top.

Ajax rates the hub radio at up to 2,000 m in open space. In a real building, walls and materials cut that down. Where a device is out of range, a ReX 2 range extender relays the signal; properties that need one are quoted.

A typical 3x2 or 4x2 takes three to four MotionProtect detectors as a bare minimum. They go in the common areas rather than the bedrooms: the living and dining area, the entry hallway, the rear hallway, the laundry entry and the garage. Someone who breaks into a house does not sit in one room, they move through it, so detectors sitting on the routes they have to walk will pick them up wherever they came in. On top of that I put a DoorProtect on the main entry door, the alfresco door and the laundry door, which is perimeter protection. Full perimeter protection is all of that plus a DoorProtect on every window in the house. You do not have to do all of it at once. A smaller system that covers the main entry and the living area is a real system, and detectors can be added to the same hub later as the budget allows.

Yes, if you fit MotionCam detectors in place of the standard ones. A MotionCam is a motion detector with a camera built into it: when it triggers it takes a short series of photos and sends them to your phone along with the alarm, so you can see whether it is a person or the dog before you decide what to do about it. Ajax rates the first photo at nine seconds. A MotionCam goes anywhere a MotionProtect would, and it is priced in the device list on this page.
