ReX 2

Radio signal range extender supporting photo verification of alarms
Rex 2
ReX 2 is compatible with Hub 2 and Hub 2 Plus control panels

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 devices 1 to ReX 2, you will ensure the security and automation of a business centre, estate, warehouse complex, or a large production facility.

5 range extenders can operate within the Ajax system to expand the coverage of the radio network 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 13 seconds 3.

Verification of alarms with snapshots

ReX 2 works with MotionCam and MotionCam Outdoor motion detectors. When triggered, they take a series of shots, helping to evaluate the events at a facility. Visual verification helps to instantly ascertain the situation, saving users from concerns and security companies from unnecessary patrol dispatches.

Guaranteed delivery of alarms and visual alarm verifications

To ensure reliable communications, we have equipped ReX 2 with four antennas and support of two proprietary radio protocols: Jeweller and Wings. Jeweller is responsible for the transmission of commands, events, and alarms, while Wings provides batch transmission of images. Ajax two-way radio communication uses frames to synchronize device communication sessions, authentication to prevent fraud, and encryption to protect against data theft.

Radio communication through steel and concrete

The next major OS Malevich update allows covering office centres with underground parking lots, sectional metal hangars, and warehouse complexes of several large buildings with a single Ajax system. Once the operating system is updated, ReX 2 will be able to connect to a hub both via radio communication and via Ethernet 4 — using the wire as a single or second communication channel.

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 strength 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 receive an alarm from a sensor and activate a siren to draw attention to the incident and deter the burglar.
Enhanced security system

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.

Hassle-free installation

ReX 2 connection and configuration process saves the installation engineer time as much as possible. 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.
