Ajax ReX 2 Black Wireless Radio Signal Range Extender with Photo Verification

Ajax ReX 2 (Black) Radio Signal Range Extender

The Ajax ReX 2 is a smart wireless repeater built to stretch the coverage of an Ajax security system across large or physically complex sites. Rather than acting as a simple signal booster, it behaves like an additional mini-hub: it groups connected devices, manages their communication with the main control panel, and keeps alarms flowing even when a facility's layout would normally cause radio interference. This black-finish unit is the second-generation ReX, adding support for the Wings protocol so it can relay photo verification images from compatible motion detectors, not just standard alarm signals.

Key Features

• Extended coverage: ReX 2 expands the radio communication range between the Ajax devices and the hub up to 2 times.
• Large-site scalability: Up to 5 range extenders can operate within an Ajax system, expanding radio network coverage to as much as 35 km².
• Photo verification support: The repeater works with Ajax MotionCam and Ajax MotionCam Outdoor detectors, which support photo verification of alarms, marking the main difference from the original ReX.
• Dual communication paths: With the OS Malevich 2.13 firmware update, the ReX 2 connects to the hub not only via radio but also via Ethernet, using the wire as the only or prioritised channel.
• Standalone smart panel behaviour: ReX 2 can act as an additional smart panel, grouping sensors together and taking control of sirens and automation scenarios if communication with the main control panel is lost.
• Reliable, fast alarm delivery: It is a radio signal range extender with support for alarm photo verification, communicating with the hub via radio and Ethernet.
• Backup power built in: It has a built-in tamper for protection against tampering and is equipped with a backup battery offering up to 38 hours of battery life.
• Secure, encrypted protocols: The system uses two-way secure radio communication based on the proprietary Jeweller and Wings protocols, which work in parallel to guarantee reliable delivery even with a weak signal.
• Sleek indoor design: The body of the device is made of durable black or white plastic in a minimalist design.

Ideal Applications

The ReX 2 Black is designed for properties where a single hub can't reliably reach every sensor. Connecting all or part of a site's devices to a ReX 2 helps secure and automate a business centre, estate, warehouse complex, or large production facility. It's a practical fit for multi-storey offices, detached outbuildings, hangars, and campuses with thick walls or long distances between rooms, especially where photo-verified alarm response is required for faster, more informed dispatch decisions.

Frequently Asked Questions

Does the ReX 2 work with any Ajax hub?
No, the range extender only works with compatible Ajax hubs, so it's worth checking your specific hub model before purchase.

Can it connect via a network cable instead of radio?
Yes, with the OS Malevich 2.13 update the ReX 2 can connect to the hub via Ethernet, using the cable as either the sole or prioritised communication channel.

How is the ReX 2 added and configured?
The device is added to the system and configured using the iOS, Android, macOS, and Windows Ajax apps.
