Ajax is smart, reliable, and lightning fast. It reacts to real dangers only, not to false alarms. If an event occurs, Ajax will notify you in a heartbeat.

Ajax has been designed and built from scratch by combining functional design, the latest technology and the best components available. This uncompromising approach made it possible to create a user friendly security system that provides top level reliability and functionality to security professionals.

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.

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.

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.
