Overview
Keep your security network connected across blind spots and large facilities with the AJAX ReX 2 radio signal range extender. Designed as a control panel repeater for Ajax systems, ReX 2 strengthens wireless coverage and improves surveillance and monitoring reliability by relaying alarms, events and MotionCam photos to the hub via dual channels — Ethernet and radio — with automatic failover. The unit supports alarm photo verification, letting security teams or remote operators quickly validate incidents and reduce false alarms.
Built for indoor installation, ReX 2 provides up to 38 hours of backup battery life during outages and includes tamper protection and radio frequency hopping to resist jamming and tampering. It pairs quickly using a QR code and is configurable remotely through Ajax apps, making it ideal for commercial, retail, and multi-site deployments. Compatible with Hub 2 and Hub Hybrid models, ReX 2 integrates seamlessly into existing Ajax security setups.
Add the AJAX ReX 2 to your security architecture to extend range, improve monitoring accuracy and speed response — a smart upgrade for any surveillance or alarm system.
