The Hub G3 Jeweller is the heart of an Ajax wireless system. It maintains constant encrypted radio communication with every connected sensor, keypad, and siren — and stays online via three independent communication channels.
Ethernet, Wi-Fi, and dual SIM (2G/LTE). The Hub stays connected to the cloud even if one or two channels fail. Critical for arming/disarming and alert delivery.
Manages up to 200 wireless Jeweller devices: sensors, sirens, keypads, key fobs, smart sockets, and integration modules. Plenty of headroom for most properties.
Pairs with MotionCam detectors to receive and forward HD photos to the Ajax app. Visual confirmation of alarms eliminates uncertainty and reduces false call-outs.
Internal battery keeps the Hub operational for up to 16 hours during a power cut — your alarm system stays armed even in extended outages.
AES encryption, frequency-hopping radio, and active jamming detection. Tamper switches alert you the moment anyone interferes with the Hub or sensors.
Each user has their own PIN, app access, time-based permissions, and event log entries. Perfect for families, shared offices, and properties with cleaners or guests.
The Hub G3 is ideal for properties where wireless flexibility matters — clean install, no mess, and the ability to expand sensors over time.
3-5 bed houses, modern flats, period properties where wired retrofit would be invasive. Hub G3 handles the typical 6-12 sensor home with capacity to grow.
High-street retail, small dental practices, hair salons, accountancy offices. Compact systems with door, window, motion, and panic protection.
Airbnbs and short-stay rentals (with cleaner access via PIN), small restaurants, cafés. Time-based user permissions are perfect for staff turnover.
Self-storage, small workshops, single-unit warehouses. Wireless installation handles awkward layouts where cable runs would be impractical.

Hub G3 pricing is straightforward — but a complete alarm system includes sensors, keypads, and installation. Here's what to expect.
Includes Hub G3 Jeweller, 4-6 motion sensors, 2-3 door contacts, keypad, outdoor siren, key fobs, and full professional installation. Final price depends on property size, sensor count, and integration requirements.
Get Exact QuoteThe Hub G3 introduces dual SIM (LTE plus 2G fallback), Wi-Fi 6 readiness, expanded device support to 200 devices (up from 100 on Hub 2), and improved photo verification handling. If you're starting fresh, Hub G3 is always the right choice. Existing Hub 2 systems can be upgraded — talk to us about migration.
The Hub G3 operates fully even when fully offline — sensors continue to detect intrusions and trigger sirens locally. The dual SIM is the safety net: if your broadband fails, mobile data takes over for cloud sync and remote alerts. For pure local monitoring without any cloud dependency, the Hub G3 is well-suited.
Yes — the Hub G3 supports up to 25 photo verification devices (MotionCam, MotionCam Outdoor, etc). When motion triggers a connected MotionCam, the Hub receives the photos and forwards them to the Ajax app and any monitoring station you've configured. This is a key advantage over older alarm systems that can only confirm "motion was detected" without visual evidence.
The Hub G3 is part of the Ajax wireless ecosystem and uses the proprietary Jeweller protocol — it doesn't connect to other manufacturers' wireless devices. However, you can keep your existing wired sensors during transition by using a Hub Hybrid 2 instead, or run both systems in parallel during a phased upgrade. We can advise during your free site survey.
The Hub G3 itself takes about 30 minutes to install — wall mount, power, network connection, and initial cloud pairing. A complete typical home system (Hub plus 6-10 sensors, keypad, siren) is a 3-5 hour installation. Larger properties take longer. Because the system is wireless, there's no drilling through walls and no disruption to your day.
Absolutely — the Ajax app gives you full control and instant alerts directly from the Hub G3. No subscription required for self-monitoring. If you want professional ARC (Alarm Receiving Centre) monitoring with verified police response, that's optional and typically £20-30/month. Your insurer may require ARC monitoring for higher-value or commercial properties.
