Secures large premises

ReX is the Ajax security system radio signal range extender, that expands the boundaries of the protected area. It controls the system devices connected to it enabling the user to place them at a considerable distance from the hub — in a multi-storey office, in a detached garage or in a large production plant. ReX doubles the signal range which potentially extends the Ajax radio coverage area up to 16 km².


Transmits alarms in 0.3 seconds


Manages the devices if the hub connection is lost


Communicates at a distance of up to 1800 m


Operates up to
35 hours on the back-up battery

Reliable link for secure communication

ReX can manage some or all the devices in the system. Yet, the number of connected devices does not affect the alarm delivery speed.

Up to 5 range extenders can operate in the security system

Enhances the security system

ReX integrates the devices into an autonomous group within the system. The extender takes full control of the situation if the connection with the hub is interrupted for some reason. If one of its detectors sends an alarm signal, ReX may activate the siren to attract attention to the incident and scare off the burglar.

The second decision-making center

ReX runs on OS Malevich and is as capable as the hub. The intelligent extender manages its connected devices and makes critical decisions in a blink of an eye. The capabilities and the role of ReX in the security system continue to evolve with the free OS Malevich updates available for all the users.

Holds off the intruder attacks

The OS Malevich unique operation logic protects ReX against software and hardware attacks and makes it resistant to viruses or exploits. Moreover, all the ReX communications are encrypted, which makes any signal interception practically impossible. And even during a blackout, ReX will continue to stay on guard of your property using the in-built back-up battery.
