What Is an Ajax Security System?
Ajax is a professional wireless security system from a Ukrainian-founded manufacturer — sensors talk to a hub over their own Jeweller protocol, and you see everything on your phone.
How It Works
Sensors around your home
Door/window, motion, smoke and other sensors get placed wherever you need them — no cables to run through walls.
Talking to the hub
Sensors communicate with the Hub over the wireless Jeweller protocol (up to ~2 km open field, less indoors depending on walls).
The hub and the app
The Hub processes signals and sends alerts to your phone via the Security System app — arm or disarm from anywhere.
What happens during an alarm
With a MotionCam sensor you get a photo for verification; the system can also connect to a professional monitoring station.
What Makes Ajax Stand Out
Jeweller wireless range
In open, line-of-sight conditions, Jeweller sensors can reach the hub up to about 2 km away — indoors, walls and materials always bring that down.
Fast, flexible installation
Wireless Jeweller sensors go up almost anywhere without running cables through walls.
Fibra — a wired option
Where cabling already exists or hardwired detection is needed, Ajax offers its own Fibra wired protocol on the same ecosystem.
Hub Hybrid does both
The Hub Hybrid model supports both wireless Jeweller and wired Fibra devices on a single hub.
MotionCam photo verification
A motion detector with a built-in camera that captures a photo during an alarm, helping confirm whether it's real.
Certified security
Many Ajax devices are certified to EN 50131 Grade 2, a European grade for intrusion-alarm systems.
What a Typical Setup Includes
A basic Ajax setup usually centers around these building blocks — the exact kit depends on your home.
- A Hub — the brain of the system
- Door/window sensors for entry points
- A motion detector (or MotionCam with photo)
- A keypad or key fob for arming/disarming
- The Security System app on your phone
Frequently asked questions
Can I install Ajax myself?
Sensors are wireless and easy to place, but a full setup — zoning, hub configuration, connecting to a monitoring station — usually benefits from a certified installer for a professional result.
What is Jeweller?
Jeweller is Ajax's own wireless radio protocol connecting sensors to the Hub, with a range of up to ~2 km in open field.
What's the difference between Jeweller and Fibra?
Jeweller is wireless, Fibra is Ajax's wired protocol on the same ecosystem — useful where cabling already exists or hardwired detection is needed.
Does MotionCam prevent false alarms?
MotionCam sends a photo during an alarm so you or a monitoring station can quickly confirm it's real — this reduces, but doesn't fully eliminate, false-alarm responses.
Can Ajax connect to a monitoring company?
Yes, Ajax hubs can connect to a professional 24/7 monitoring station through the operator's monitoring software.
