More applications of a security system
Range extenders expand the boundaries of the protected area and give even more freedom to place security system devices. By connecting all or part of the devices¹ to ReX 2, you will ensure the security and automation of a business centre, big estate, warehouse complex, or a large production facility. 5 range extenders can operate within the Ajax system to expand the radio network coverage up to 35 km² ². Events and alarms are transmitted instantly, and the first photo verification snapshot is delivered to a monitoring station and users in just 10 seconds³.

Verification of alarms with snapshots
ReX 2 works with MotionCam and MotionCam Outdoor motion detectors. When triggered, they take a series of animated pictures, helping to assess the situation at the facility. This reduces unnecessary patrol dispatches and saves the clients' nerves.

Guaranteed delivery of alarms and photo verifications
To ensure reliable communications, we have equipped ReX 2 with four antennas and support for two proprietary radio protocols: Jeweller and Wings. Jeweller provides the transmission of commands, events, and alarms, while Wings ensures the transmission of visual data packages. Ajax two-way radio communication uses frames to synchronize device communication sessions, authentication to prevent spoofing, and encryption to protect against data theft.

Radio communication through steel and concrete
With the OS Malevich 2.13 operating system update, the ReX 2 range extender will connect to the hub not only via radio but also via Ethernet using the wire as the only or additional communication channel. A single Ajax system can cover the facility like an office centre with underground parking, or a sectional metal hangar, or a warehouse complex of several large buildings.

Enhanced security system
ReX 2 works as an extra intelligent control panel: it connects devices into an autonomous group and takes over control at the right time. Thanks to automatic adjustment of signal power and frame synchronization, any number of system devices can be connected to ReX 2 — the reliability of communication will not be affected by this. If, for some reason, radio communication with the hub is interrupted, ReX 2 will continue to operate via Ethernet. If a connection via Ethernet is lost, ReX 2 receives an alarm from a detector and activates a siren to draw attention to the incident and deter the burglar.

Ready to resist intruder attacks
ReX 2 is protected from attacks at the software and hardware levels. It runs on the OS Malevich operating system, which is immune to viruses. All data transmitted by the range extender is encrypted. Thanks to the built-in backup battery, a sudden blackout at a facility will not be a problem.

Evolving, not outdated

ReX 2 runs on OS Malevich, a real-time operating system developed by Ajax Systems. The OS Malevich modular architecture allows its regular updates. The operating system updates over the air. The process does not need the installer or user involvement and takes minutes when the security system is disarmed.

Hassle-free installation
ReX 2 connection and configuration process greatly saves the installer time. To add a range extender to a system, simply scan a QR code with the Ajax app and assign it a name and a room. The device is also configured in real time in the app. If necessary, ReX 2 can be disabled or reconfigured without site visits.

¹ReX 2 cannot be connected to another range extender.

²When using five radio signal range extenders in the system.

³When transmitting images from MotionCam (default settings) through the ReX 2 range extender and the hub. The hub should be connected to the internet via Ethernet, Wi-Fi, or LTE.
