How to Choose an Ajax Kit for Your Home
Ajax offers a flexible wireless security system, but the right kit depends on your home — its size, your priorities, and its layout. Here are the criteria to think through before you decide.
What shapes your choice
Home size and layout
A bigger home or multiple floors means more sensors and a more careful hub placement, so the Jeweller radio signal reaches every room.
Do you want photo verification
MotionCam detectors capture a photo when an alarm triggers, so you or a monitoring station can confirm it's real — whether that's worth it over standard motion/door sensors depends on your priorities.
Could the signal face obstacles
Thick walls, reinforced concrete, or metal structures can weaken wireless coverage — worth considering a wired Fibra setup or a Hub Hybrid, which supports both.
Plans for a monitoring station
If you might want professional 24/7 monitoring later, it's worth factoring that in when choosing the hub and system setup now.
What's worth knowing about Ajax
Jeweller radio range
In open, line-of-sight conditions Jeweller can reach up to roughly 2 km — indoors the real range is always shorter, depending on walls and materials.
Jeweller wireless protocol
Ajax's own radio protocol connecting sensors to the hub — fast to install without running cables.
Fibra wired alternative
A wired option for detectors and modules, useful where cabling already exists or wireless isn't suitable.
Hub Hybrid combines both
Hub Hybrid supports wireless Jeweller devices and wired Fibra devices on one hub — handy for mixed setups.
MotionCam photo verification
A motion detector with a built-in camera that captures a photo on alarm, helping confirm whether it's real.
EN 50131 Grade 2 certification
Many Ajax devices are certified to EN 50131 Grade 2, a European security grade for low-to-medium risk.
What to think through first
Before you picture a specific kit, run through these points.
- How many rooms/floors need coverage, and where the hub should sit
- Whether you want standard motion/door sensors or MotionCam photo verification
- Any spots with thick walls or metal that could weaken the signal
- Whether you plan to connect a professional monitoring station now or later
- Whether you'll self-manage via the Security System app or want PRO installer help
Frequently asked questions
How many sensors do I need?
That depends on your home's size, layout, and desired coverage — the exact number is best determined by a site visit or consultation, not a generic guide.
Will the Jeweller signal work in my home?
In open, line-of-sight conditions the range can reach around 2 km, but indoors it's affected by walls and materials — thick or metal walls can reduce coverage.
What's the difference between Jeweller and Fibra?
Jeweller is the wireless protocol for fast installation; Fibra is a wired alternative, useful when cabling already exists or wireless isn't ideal. Hub Hybrid supports both.
Does MotionCam eliminate false alarms?
Photo verification helps confirm whether an alarm is real before anyone reacts, cutting down unnecessary responses — but it doesn't fully eliminate the chance of false alarms.
Can I figure out the right kit myself?
This guide gives you criteria, not a ready answer — the exact kit is best worked out by visiting the site or talking it through, since every home is different.
