Overview
The Ajax Hub (2G) Jeweller is the control panel of an Ajax wireless alarm. It links the detectors, keypads and sirens in your home, office or shop over the Jeweller radio, and alerts you in the Ajax app, by SMS or by call when something happens. It connects to the internet over Ethernet and a 2G SIM card, and keeps running on its backup battery during a power cut.
Is it right for you?
- Choose it for a home, flat or small business that needs up to 100 wireless devices, 50 users and 9 security groups.
- It does not support MotionCam photo verification. If you want photos on alarm, choose Hub 2 (2G) or Hub 2 Plus.
- It has one SIM slot and uses 2G only. Where 2G coverage is poor, Hub (4G) is the better choice.
- It supports 5 automation scenarios and 1 range extender; larger buildings may need Hub 2 Plus.
