Description
The Ajax ReX 2 Jeweller is the most capable range extender in the Ajax ecosystem, extending your alarm system’s wireless coverage across larger buildings, outbuildings, and complex multi-floor premises where a single hub cannot reach every device. Unlike the original ReX, the ReX 2 supports both the Jeweller protocol for alarms and events and the Wings protocol for photo verification, meaning your Ajax MotionCam detectors can send visual alarm images through the range extender just as they would through the hub itself.
This listing is for the Ajax ReX 2 (Range Extender) in White, professionally supplied and installed by CCTV Aware, Ajax Certified Specialists based in Chelmsford, Essex.
Extends coverage to up to 1,700 metres
The ReX 2 communicates with the hub over Jeweller radio at ranges of up to 1,700 metres in open space, and relays signals from connected detectors and devices across the same distance again. Up to five ReX 2 units can be added to a single Ajax hub, and each extender supports up to 199 connected devices, depending on the hub model. For a large warehouse, a sprawling farmhouse, or a business with separate buildings on the same site, this gives the flexibility to build a single unified Ajax system without running cables between structures.
Wings protocol: photo verification through the extender
The ReX 2 is the only Ajax range extender that relays photo streams from Ajax MotionCam and MotionCam Outdoor detectors. When a MotionCam triggers in an area covered by the ReX 2, the alarm images travel via the Wings channel through the extender to the hub and on to your monitoring centre or the Ajax app. Photo delivery takes around 18 seconds via Wings or as little as 10 seconds when the ReX 2 is connected via Ethernet, giving your team the visual context they need to respond appropriately.
Ethernet connection for added resilience
As well as its radio link, the ReX 2 features a built-in 8P8C Ethernet port. When connected to your local network, the Ethernet channel acts as a primary or backup path for all alarms, events, and photos, reducing reliance on the radio link in environments with heavy RF interference. This dual-path architecture is particularly valuable in commercial and industrial settings where radio conditions can be unpredictable.
24-hour battery backup and tamper protection
Mains powered from any standard 110–240V socket, the ReX 2 carries a built-in 2Ah Li-ion rechargeable battery that provides up to 24 hours of backup when the mains supply is interrupted and Ethernet is disabled. A tamper alarm is triggered immediately if anyone attempts to detach the device from its SmartBracket mounting panel. The unit is designed for indoor installation and is compatible with the Ajax Hub 2 and all other compatible Ajax hubs.

Yes. We can install CCTV as discreetly as possible, depending on your property and coverage requirements.
Options can include:
- Compact camera styles
- Higher mounting positions where appropriate
- Tidy cable routes and minimal visible trunking
- Recorder installed out of sight in a secure location
If your priority is a low profile install, tell us at quotation stage so we can recommend the best approach for your layout.
The recorder (DVR or NVR) is normally installed indoors in a secure, sensible location with good ventilation.
Common locations include:
- A cupboard or utility area
- An office
- A comms cabinet or rack
We typically install it near your internet router if you want remote viewing on your phone, as it needs a network connection.
If you have a preferred location, let us know during the quote stage and we will advise if it is suitable.
In many cases, yes.
Whether you can add cameras later depends on:
- How many spare channels your recorder has
- Whether the recorder has spare capacity on the hard drive
- Whether cable routes and power options are available
If you think you might expand in future, we can design the system with this in mind, for example fitting an 8 channel recorder for a 4 camera install, or leaving suitable cable routes.
Yes. Your CCTV system records locally to the recorder (DVR or NVR). If your broadband drops out, it will still continue recording as normal.
What you will lose during an internet outage is:
- Remote viewing from your phone or PC
- Push notifications and alerts to your phone
- Remote playback access
Once the internet comes back online, remote viewing and notifications will resume.
Recording time, also known as retention, depends on a few things:
- Number of cameras
- Camera resolution (for example 6MP, 8MP)
- Recording mode (continuous 24/7, motion only, or a mix)
- Frame rate and bitrate settings
- The hard drive size fitted to your recorder
As a rough guide, higher resolution and 24/7 recording will reduce retention. Motion based recording can greatly increase retention, but it depends on how busy the scene is.
We generally specify our systems to give you a retention period of 21 days.
Hikvision CCTV systems can support a multitude of notifications that can be configured to perform various actions from alerting your mobile phone to activating a parking barrier.
That being said, this guide talks about the three main notification options.
Motion Detection
In its simplest form, this is when an object enters the camera view area and a motion is triggered.
Line Crossing
An invisible line can be drawn on a particular area of your camera view area, for example the driveway threshold or the garden boundary. Once an object crosses over that line (from either way) - a line crossing is triggered.
Intrusion Detection
This is similar to Motion Detection but more specific. With Intrusion Detection an invisible quadrilateral shape can be drawn on a particular area of your camera view, for example directly outside your front door. Once an object then enters that area - an intrusion detection is triggered.
With all of the options above, the system is unable to detect the difference between a human, pet or other object. This can often result in false notifications being triggered to the user. In addition to this, if the system generates the notification - it is then down to your broadband provider (router) to push the notification out to your mobile device. This will often fail if your provider is not quite up to scratch or your mobile phone is currently in an area with poor coverage.
Because of this, we do not provide support on notifications that are sent to your mobile device.
Unfortunately, no.
We are authorised and Certified by Hikvision UK to supply and install their products.
We are unable to provide you with an installation only service if you have purchased your own equipment as we are not insured to do so.

Our prices are fixed, so the cost of your installation will really depend on the amount of cameras you require and the type of system.
