Ajax ReX 2 | Signal Extender with Photo Verification & Ethernet | Jeweller/Wings
Summary
The ReX 2 Jeweller is an advanced radio signal range extender designed for Ajax security systems with integrated support for alarm photo verification. Building upon the original ReX Jeweller, this second-generation model introduces the Wings communication protocol alongside Jeweller, enabling it to transmit not only alarms and events but also photographs captured by MotionCam detectors throughout the facility.
Engineered for large and complex installations, ReX 2 Jeweller extends wireless communication range up to 1,700 meters in open space, allowing Ajax systems to protect expansive properties including office centers with underground parking, metal hangars, and multi-building warehouse complexes. The range extender features dual connectivity options—communicating with the hub via both radio protocols (Jeweller and Wings) and Ethernet cable—ensuring reliable data transmission even through steel and concrete structures where radio signals may be compromised.
With support for up to 5 range extenders per compatible hub and capacity for up to 199 devices per extender, ReX 2 Jeweller enables scalable security deployments. Photo delivery times are impressively fast, with images transmitted in as little as 6-10 seconds via Ethernet or 8-18 seconds via Wings radio protocol depending on detector type and resolution. The device features a built-in rechargeable Li-ion battery providing up to 38 hours of backup operation when mains power is disconnected, along with tamper protection and encrypted communication for enhanced security.

FAQs
What is the difference between ReX Jeweller and ReX 2 Jeweller?
ReX 2 Jeweller adds the Wings communication protocol for transmitting photos from MotionCam detectors, while the original ReX Jeweller only supports the Jeweller protocol for alarms and events. ReX 2 also features Ethernet connectivity with OS Malevich 2.13 or higher, dual-channel communication with automatic switching, and an extended battery life of up to 38 hours. Both models can be used together in the same Ajax system.
How fast are photos delivered through ReX 2 Jeweller?
Photo delivery speed depends on the communication channel, detector type, and image resolution. Via Ethernet, photos are delivered in 6-17 seconds depending on the detector and resolution. Via Wings radio protocol, delivery takes 8-53 seconds. For example, a MotionCam (PhOD) Jeweller photo at default 320×240 resolution is delivered in approximately 10 seconds via both Ethernet and Wings. Alarm delivery remains constant at 0.3 seconds regardless of the channel.
Can ReX 2 Jeweller work without Ethernet connectivity?
Yes, ReX 2 Jeweller can operate using only the Jeweller and Wings radio protocols without Ethernet. However, Ethernet provides several advantages including faster photo transmission, increased reliability through dual-channel redundancy, and the ability to penetrate metal structures and concrete where radio signals may be weak. Ethernet can serve as the sole communication channel or work alongside radio protocols for maximum fault tolerance.
How many ReX 2 Jeweller units can I connect to my Ajax hub?
You can connect up to 5 ReX 2 Jeweller range extenders to Hub 2 (2G), Hub 2 (4G), Hub 2 Plus, and Hub Hybrid (2G/4G) models. The original Hub supports only 1 ReX Jeweller. You can mix ReX Jeweller and ReX 2 Jeweller models in the same system within these limits. Note that ReX 2 Jeweller does not increase the total number of devices your hub can support—it only extends the wireless range.
How many devices can connect to a single ReX 2 Jeweller?
ReX 2 Jeweller can connect up to 99 or 199 devices depending on your hub model. Hub 2 (2G), Hub 2 (4G), and Hub Hybrid models support up to 99 devices per extender, while Hub 2 Plus supports up to 199 devices. The devices connected through ReX 2 count toward your hub’s total device capacity.
Which Ajax hubs are compatible with ReX 2 Jeweller?
ReX 2 Jeweller is compatible with Hub 2 (2G), Hub 2 (4G), Hub 2 Plus, Hub Hybrid (2G), and Hub Hybrid (4G). It requires OS Malevich 2.13 or higher for Ethernet connectivity. ReX 2 Jeweller is not compatible with the original Hub, Hub Plus, uartBridge, or ocBridge Plus. Connection to other range extenders is also not supported.
Does ReX 2 Jeweller work with all Ajax detectors?
ReX 2 Jeweller works with all Ajax wireless devices that use the Jeweller protocol. For photo verification, it supports all MotionCam detector models including MotionCam Jeweller, MotionCam (PhOD) Jeweller, MotionCam Outdoor Jeweller, MotionCam Outdoor (PhOD) Jeweller, MotionCam Outdoor HighMount (PhOD) Jeweller, Superior MotionCam (PhOD) Jeweller, Superior MotionCam HD (PhOD) Jeweller, and Superior MotionCam AM (PhOD) Jeweller.
How do I set up Ethernet connectivity on ReX 2 Jeweller?
Connect ReX 2 Jeweller and your Ajax hub to the same network through a router using standard Ethernet cables. In the Ajax app, go to ReX 2 Jeweller settings and enable “Connection via Ethernet.” You can choose between DHCP (automatic) or static IP address configuration. The hub and range extender must be on the same network, which must allow broadcast queries and have port 4269 open for all traffic. Direct Ethernet connection between hub and ReX 2 without a router is not supported.
What happens if ReX 2 Jeweller loses connection with the hub?
If ReX 2 Jeweller loses connection via both Ethernet and radio channels, devices connected through it will be unable to communicate with the hub until connection is restored. The LED indicator will turn red to show connection loss. When Ethernet is enabled and one communication channel fails, the system automatically switches to the other available channel. If a device loses connection with a range extender, it will not automatically reconnect to the hub or another extender.
How long does the ReX 2 Jeweller battery last during a power outage?
The built-in 2 Ah Li-ion battery provides up to 38 hours of backup operation when external power is disconnected and Ethernet is not in use. When connected via Ethernet, battery life is reduced to up to 12 hours. The battery recharges in up to 4 hours to 80% capacity when external power is restored. The device will flash every 10 seconds when operating on battery power.
Can I install ReX 2 Jeweller outdoors?
No, ReX 2 Jeweller is designed for indoor installation only and has an IP20 protection rating. It should be installed in locations with temperatures between -10°C and +40°C and humidity up to 75%. Installing it outdoors or in harsh environments may cause device malfunction and void the warranty.
Where should I install ReX 2 Jeweller for optimal performance?
Install ReX 2 Jeweller between the hub and devices with weak signal strength—ideally where both connections show 2-3 signal bars. Do not install near devices with only 1 bar or no signal, as the extender does not amplify signals. Avoid placement near metal objects, mirrors, or within 1 meter of routers and power cables. The device should be hidden from view to reduce tampering risk. Use the signal strength tests in the Ajax app to verify optimal placement before final installation.
