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.

Guaranteed delivery of
alarms and photos
ReX 2 is equipped with four antennas and supports two
radio protocols: Jeweller and Wings. The maximum radio
communication range of each protocol is 1,700 meters in
an open space.
Jeweller transmits commands, events and alarms. Wings
provides packet transmission of images, even when the
signal strength is unstable and the communication fails.
This is possible due to the built-in algorithms for checking
and uploading 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.
