ReX
Home Automation
Wireless radio signal range extender
PAN India — B2B Distribution Network
ReX is the radio signal range extender that boosts the range of all Ajax security system devices and manages their communication with the hub. The intelligent radio signal range extender enables users to place Ajax devices at a considerable distance from the hub for protecting multi-story offices, detached buildings, and even production plants.
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.
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.
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.
To connect ReX to the system, scan the QR code, name it, and switch it on. Then, select the devices which should operate via the range extender from the list. Proceed by installing ReX in a safe spot. No disassembling required. Just use the SmartBracket mount.
