AJAX Superior Grade 3 — security at one of the highest levels
This is not a basic package and not a door-to-door sales story. The AJAX Superior line is designed for owners who want the best: fully wireless, independently tested to EN 50131 Grade 3, and built for large villas, high-value homes and situations where sabotage, masking and interference are not an option.
The Superior Grade 3 solution
The Superior Grade 3 solution from Ajax Systems is designed to protect the most demanding sites — from banks and jewellery stores to critical infrastructure, and increasingly also high-value villas. The solution includes wired and wireless products for intrusion protection: quick to install, simple to set up and maintainable remotely via the Ajax apps. Every device is thoroughly tested and certified to EN 50131 (Grade 3), confirming compliance with the strictest globally recognised security standard.
The system can be tailored to the specific needs of each project. Choose a fully wireless or wired system, or build a hybrid installation with both. Ajax hubs make it possible to scale systems of any size: from compact installations with only a few devices to large projects with hundreds of wired and wireless devices in one system. Products for video surveillance, automation, fire safety and — where appropriate — third-party devices can be integrated with Superior Grade 3 into one powerful security solution.
We install this as an accredited Ajax Systems Partner — with bespoke design, professional placement and no mandatory monthly subscription. On this page we focus on the Superior Jeweller G3 line for indoor security: the products you see below form the core of a system that is not comparable to what a standard subscription provider demonstrates at your door.
Honest advice: are you mainly choosing on price or a “quick basic kit”? Then Superior Grade 3 is probably not the right choice. Are you choosing maximum reliability, professional placement and technology that meets commercial-grade requirements — then this is exactly what you are looking for. We explain on site what is and is not needed.
Who is Superior Grade 3 intended for?
Well suited
- Owners of large villas, estates or homes with multiple floors and valuable contents.
- Clients who consciously choose the highest protection level — not the cheapest package.
- Situations where insurer, business operations or own risk policy impose higher requirements.
- Owners who want to seriously cover sabotage, masking and jamming — on top of standard Grade 2.
- Homes where outdoor detection can be added later; indoor forms the Grade 3 core for now.
Not the right choice if…
- You are mainly looking for the lowest monthly price or a standard subscription package.
- A simple basic setup with a few sensors is sufficient.
- You do not want to pay extra for laboratory-tested Grade 3 sabotage protection.
- You expect a representative with a demo case to offer the same level — they do not.

Grade 3For those who want the highest level
Maximum securitySuperior Hub G3 · Superior MotionCam G3 PhOD · Superior StreetSiren Plus G3
The Ajax Superior line: the world’s first fully wireless system with Grade 3 certification (EN 50131). Superior may only be sold and installed by accredited Ajax Systems Partners, like us.

- Superior Hub G3 JewellerControl panel with Ethernet, Wi-Fi and two SIM cards (2G/LTE) that switches over automatically if a connection drops. Wireless range up to 3,500 m in open space. Detects jamming and reports it.
- Superior MotionCam G3 (PhOD) JewellerThe world’s first Grade 3 motion detector with a built-in camera. Detects up to 15 m, even when someone crawls or tries to cover the sensor (anti-masking). HD photos with HDR, on alarm or on request (Photo on Demand).
- Superior StreetSiren Plus G3 JewellerThe world’s first wireless Grade 3 outdoor siren. The siren detects jamming itself. Volume adjustable from 85 to 107 dB, IP54 and IK08 enclosure.
Installation at a later date remains € 1,199 excl. VAT. The backup battery keeps the hub running during a power cut and costs € 50 excl. VAT extra.
Good to know. If you expand, do so with Superior devices: only then does the whole system run on the Grade 3 protocol (Superior Jeweller). The Superior MotionCam G3 has no pet immunity.
What makes Grade 3 different from a standard subscription?
A door-to-door representative usually demonstrates a commercial package: limited sensors, contract, call centre and hardware not built for Grade 3 requirements. AJAX Superior is designed for professional installation and must meet strict European standards for burglar alarm systems.
Grade 3 requires, among other things, anti-masking, tamper detection, jamming detection, spoofing protection and communication failure within seconds. Superior Jeweller is the first wireless protocol to meet this bar — with encrypted two-way communication, frequency hopping and polling from 12 seconds.
The result: a wireless system with a reliability profile comparable to what you expect from a professional wired system — without pulling cables through walls and plasterwork. More background: licence & certification and jamming & signal interference.

Superior Jeweller G3 vs. standard Jeweller
Important: Superior G3 devices and standard Jeweller sensors can work together in one system, but Grade 3 and enhanced frequency hopping only apply if all devices are G3. How we still combine Grade 2 outdoor sensors responsibly is explained below.
The difference lies in protocol, sabotage layers and certification: Superior Jeweller is built for Grade 3, with stricter requirements for masking, tampering and connection monitoring. Standard Jeweller is excellent for Grade 2 — but it is not the same level as what you see below.
Superior Jeweller & frequency hopping
Grade 3 only stays Grade 3 if the whole system is G3
The Superior Hub G3 communicates with its devices via Superior Jeweller, the radio protocol for Grade 3 (EN 50131). It combines advanced encryption with enhanced frequency hopping: hub and devices switch together, following a defined pattern, between 16 frequencies in 4 frequency bands. If one channel is jammed, the message simply goes through another channel.
One Grade 2 device is enough to switch that off. According to Ajax Systems, enhanced frequency hopping only works if all wireless devices in the system support Superior Jeweller. Add even one device using the regular Jeweller protocol (such as a Grade 2 Baseline sensor) to the hub, and the whole system falls back to regular operation on 2 frequencies and is limited to Grade 2. Encryption does stay active.
Note: not every device with ‘Superior’ in its name supports Superior Jeweller. It concerns the G3 devices, plus a few Superior models with recent firmware (MotionCam AM, MotionCam HD and StreetSiren DoubleDeck). A regular ReX or ReX 2 range extender or a SpeakerPhone even disables enhanced frequency hopping in the entire system.
Grade 2 outdoor sensors in a Superior system? Then a Superior ReX G3
For outdoor detection (curtain and outdoor PIR) we often use Grade 2 sensors. If you want to combine them with a Superior system, we recommend an AJAX Superior ReX G3 Jeweller (range extender). Ajax describes exactly this solution: all devices without enhanced frequency hopping are connected to the ReX G3, so the G3 devices connected directly to the hub keep enhanced frequency hopping. This only works with a ReX G3, not with a regular ReX.
Superior Hub G3 with G3 devices onlyOptionally with a Superior ReX G3. Grade 3, with enhanced frequency hopping in the whole system.
G3 core on the hub, Grade 2 outdoor sensors via a Superior ReX G3Enhanced frequency hopping stays active for the G3 devices on the hub. The system as a whole is Grade 2.
Grade 2 device directly on the hub, or a regular ReX/ReX 2No enhanced frequency hopping in the system. The system is Grade 2.
To be fair: as soon as there are Grade 2 devices in the system, the installation as a whole is no longer a Grade 3 installation, not even with a ReX G3. What you do keep: the G3 core indoors communicates with enhanced frequency hopping against jamming, and the Grade 2 outdoor sensors still report interference via Jeweller. In the Ajax app you can see the ‘Frequency hopping’ status at the hub and the range extender. If it is not active, the app shows which device is the cause.

Wireless — with the reliability of wired

Many clients ask: “Is wireless really as reliable as wired?” With Superior Grade 3 the answer is: for this application, yes — provided it is professionally designed and placed. The system uses two-way communication, encryption, frequency hopping against jamming, authentication against spoofing and polling every 12 seconds. Connection loss is reported within 36 seconds.
That is exactly the kind of redundancy you know from a wired Grade 3 system — only without structural intervention. For a villa in Spain that means: no chases in marble or plasterwork, yet the same serious protection level.
Note: the products on this page focus on indoor security. Outdoor detection with other AJAX lines can be added later; we design the whole as one plan.
What does it deliver for you in practice?
Less risk of sabotage
Masking, dismantling, jamming and spoofing are actively detected and reported — not only when it is too late.
Evidence when in doubt
With MotionCam G3 PhOD you (or your monitoring centre) see what happened — no more blind alarms.
Ownership, no lock-in
You buy the system; no mandatory monthly contract as with most door-to-door providers. See without subscription.
