Hub 2 (2G) / (4G) User manual | Ajax Systems Support
When choosing a location, consider three main factors:
Jeweller signal strength,
Wings signal strength,
cellular signal strength.
Locate Hub 2 in a place with stable Jeweller and Wings signal strength of 2–3 bars with all
connected devices (you can view the signal strength with every device in the list of states for a
respective device in the Ajax app).
When choosing a place for installation, consider the distance between the devices and the hub
and any obstacles between the devices hindering the radio signal passage: walls, intermediate
Coors, or large-size objects located in the room.
To roughly calculate the signal strength at the place of installation, use our
range calculator
The cellular signal strength of 2–3 bars is necessary for the correct stable operation of SIM
cards installed in the hub. If the signal strength is 0 or 1 bar, we cannot guarantee all events and
alarms by calls, SMS, or mobile internet.
Be sure to check the Jeweller and Wings signal strength between the hub and all devices at the place of
installation. If the signal strength is low (a single bar), we cannot guarantee a stable operation of the security
system since a device with a low signal strength may lose connection with the hub.
