AJAX REX 2 White

Ajax REX 2 White

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 devices2 to ReX 2, you will ensure the security and automation
of a business centre, estate, warehouse complex, or a large production facility

Repeater 220VAC or 12VDC with 12V PSU Module

Radio signal range extender supporting photo verification of alarms
5 range extenders can operate within the Ajax system to expand the coverage of the radio network up to 35
km3
. Events and alarms are transmitted instantly, and the first photo verification snapshot is delivered to a
monitoring station and users in just 18 seconds.
More supported devices
● Intrusion detectors with photo verification
● Control devices
● Fire detectors
● Panic buttons
● Leak detectors
● Automation devices
● Sirens
● Integration modules
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.
Privacy first
The detector activates its camera when the security system is armed and the motion is detected. Shots are
encrypted at every stage of transmission. While stored on the Ajax Cloud server, no pictures are processed or
analyzed. Visual alarm verifications can only be seen by users with access rights to the events feed with push
notifications enabled and by employees of the security company if the security system is connected to a
monitoring station.
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.
● Alarm in 0.3 seconds
● The first photo in 18 seconds4
Radio communication through steel and concrete
The next major OS Malevich update will allow to cover office centers 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
Ethernet5 — using the wire as a single or second communication channel.
● Transmission of events and visual alarm verifications via cable
● Encryption of transmitted data
● Automatic change of communication channel in case of break
● Connecting via router
Enhanced security system
ReX 2 integrates detectors into an autonomous group within the system. If for some reason radio
communication with the hub is interrupted, ReX 2 will take over: receive an alarm from the detector and
activate 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.
● Up to 38 hours of backup battery life
● Informs about interferences and jamming
● Detects attempts to dismantle and open the enclosure
● Immunity against viruses
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.
● Connection ▸ Connecting via a QR code
● Installation ▸ Installing on the SmartBracket mounting panel without disassembling the enclosure
● Setup ▸ Setting up in the Ajax app
