Ajax Hub 2 Plus (4G): the top model for large and complex installations
The Hub 2 Plus is the most powerful wireless control panel from Ajax. It monitors all your detectors via the encrypted Jeweller radio and sends photos along immediately in the event of an alarm thanks to MotionCam.
The Hub 2 Plus has four communication channels working in parallel: Ethernet, Wi-Fi and two SIM cards with 2G, 3G and 4G. This provides maximum redundancy. The system supports MotionCam photo verification and manages up to 200 devices, so even large and complex premises are covered in one go. You set it up in the free Ajax app; you pair detectors with a single click and the system switches frequency automatically in the event of jamming.
Why the Ajax Hub 2 Plus
MotionCam photo verification
In the event of an alarm, the system sends photos along, so you can see straight away whether something is really wrong. Photo on alarm, on request, per scenario or on schedule.
Four communication channels
Ethernet, Wi-Fi and two SIM cards with 2G, 3G and 4G work in parallel. If one channel drops out, the system stays online via the others.
More powerful hardware
The Hub 2 Plus is the most efficient control panel from Ajax: a processor 4.5x faster and 8x more flash memory than the Hub 2. As a result, the system keeps running smoothly for years and continues to receive new updates.
Up to 200 devices
Manages up to 200 Ajax devices, 200 users, 25 security groups and 64 scenarios. Built for large or complex installations.
Jeweller radio
Encrypted two-way radio with dynamic key. Range of up to 2000 m in open terrain and automatic frequency hopping in case of jamming.
Backup during a power failure
The built-in Li-ion battery keeps the system active for up to 15 hours if the power fails.
No subscription
Control and configuration via the free Ajax app. You only need a SIM card for the mobile backup.

Self-installation
The Hub 2 Plus is intended for indoor installation. Mount it using the supplied SmartBracket, connect the mains power supply and the network cable, and insert one or two SIM cards if you want mobile back-up. You do not need a cable for Wi-Fi. You then pair the Hub in the free Ajax app (iOS and Android) and add detectors with a single click. Mounting materials are included in the box.

Manual and compatibility
Which Ajax Hub suits you?
Compact and wireless, keenly priced
The Hub (2G) is the affordable entry-level option without photo verification, for a small, fully wireless system.
You want photos on an alarm
From the Hub 2 (4G) onwards you get photo verification with MotionCam. The logical choice for most homes.
Large or complex premises
The Hub 2 Plus (4G) (this page) adds Wi-Fi as an extra channel, for maximum redundancy.
Wired system (Fibra)
The Hub Hybrid (4G) combines wired Ajax Fibra with wireless Jeweller, for professional installations.
The Ajax hubs compared
The difference between the hubs lies mainly in the connection (Ethernet, Wi-Fi, 2G or 4G), photo verification with MotionCam, the capacity and the system type (wireless only or hybrid with wiring). The Hub 2 Plus also has the most powerful hardware, with a processor 4.5 times faster and 8 times more flash memory than the Hub 2.
| Model | Connection | Wi-Fi | MotionCam | System type | Suitable for |
|---|---|---|---|---|---|
| Hub (2G) | Ethernet + 2G (1 SIM) | No | No | Wireless | Entry level, small system without photo verification |
| Hub (4G) | Ethernet + 2G/4G (1 SIM) | No | No | Wireless | Small system with strong mobile back-up (LTE) |
| Hub 2 (2G) | Ethernet + 2G (2 SIM) | No | Yes | Wireless | Medium-sized, with photo verification |
| Hub 2 (4G) | Ethernet + 2G/3G/4G (2 SIM) | No | Yes | Wireless | Medium-sized, photo verification plus LTE back-up |
| Hub 2 Plus (4G) this model | Ethernet + Wi-Fi + 4G (2 SIM) | Yes | Yes | Wireless | Large or complex, maximum redundancy |
| Hub BP (4G) | 4G only, no network cable (2 SIM) | No | Yes | Wireless | Locations without mains power or cabling, runs on battery |
| Hub Hybrid (4G) | Ethernet + 4G (2 SIM) | No | Yes | Hybrid (wired + wireless) | Professional, (partly) wired Fibra systems |
MotionCam stands for photo verification: in the event of an alarm, the system sends photos along, so you can see immediately whether something is really wrong. Only the Hub 2 models and newer support this.
Frequently asked questions about the Ajax hubs
What is the difference between the Hub and the Hub 2?
The Hub 2 adds two things compared with the original Hub (2G and 4G): photo verification with MotionCam and a second SIM card. The original Hub does not support MotionCam. If you need photos with an alarm, choose at least a Hub 2 (4G).
What is the difference between the Hub 2 and the Hub 2 Plus?
The Hub 2 Plus adds Wi-Fi as a fourth communication channel (in addition to Ethernet and two SIM cards) and has a higher capacity. This makes it suitable for large or complex installations. For an average home, the Hub 2 (4G) is more than sufficient.
Which hubs support photo verification (MotionCam)?
MotionCam photo verification works on the Hub 2, Hub 2 Plus, Hub Hybrid and Hub BP. The original Hub (2G) and Hub (4G) do not support it.
2G is being phased out. Will my 2G hub still work?
Yes. Via the network cable (Ethernet), a 2G hub continues to work fully; only the 2G mobile back-up stops once the 2G network is switched off. For new installations we recommend a 4G model, such as the Hub (4G) or Hub 2 (4G).
Do I need a subscription?
No. The Ajax app is free and requires no subscription. You only need an M2M SIM card if you want to use the mobile back-up (2G or 4G) alongside your internet connection.
What is the Hub Hybrid?
The Hub Hybrid is the only Ajax hub that combines wired Ajax Fibra with wireless Jeweller devices. With it you build a hybrid system, useful for professional or (partly) cabled installations and for thick walls of steel or concrete.

Very reliable system
Paul Poels (verified owner) –
Easy to install and configure. And the range is not a problem for our home, even in the far corners of the house. What gets five stars from me is the activation/deactivation of the alarm in the app. The Ajax system has very extensive possibilities, so that at times you can no longer see the wood for the trees. A proper manual for each device is included, but I searched in vain for the whole story of the installation, step by step. But now that everything is installed and fully operational, the operation is quite clear.
