ReX2 is the Ajax security system radio signal range extender, that expands the boundaries of the protected area. It controls the system devices connected to it enabling the user to place them at a considerable distance from the Hub2/Hub2 Plus - in a multi-storey office, in a detached garage or in a large production plant. ReX doubles the signal range which potentially extends the Ajax radio coverage area up to 35 km².

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.
