Nomad Systems · Ajax Authorized Installer
Our preferred intrusion alarm for Texas properties, from a home or shop to a large commercial building. Encrypted two-way radio, devices that report when something is wrong, and sensors that belong in a finished room.
Why Nomad chooses Ajax
Ajax is our preferred intrusion line because of how the sensors and the hub protect their radio link, how the system watches its own devices, and how the hardware sits in a finished room.
On the air
Sensors and the hub speak both ways over Ajax’s Jeweller radio. Messages use block encryption with a key that changes, and the hub authenticates each device every time they communicate. A device that does not belong is not treated as part of the system.
When the air is noisy
Jeweller can switch channels when interference shows up. If jamming is detected, or the hub loses contact with a device, it sends an alert. With an active monitoring agreement, the monitoring company is alerted too. Interference can still happen. The system is built to say so.
Alerts for
Supervision
Sensors report in regularly, including battery, signal, and state. A tamper alert is sent if someone tries to pull a sensor or the hub off its mount, or open a sensor housing. You hear about a missing or disturbed device, not only about a door opening.
Off the property
Jeweller stays local, between the sensors and the hub. The Hub 2 Plus we install reaches the outside world over Ethernet, Wi-Fi, and two cellular SIMs, and it can switch among those paths. A built-in backup battery covers a power cut. Reporting to a monitoring center still needs an active monitoring agreement.
Optional
Compatible MotionCam detectors can provide photos when an alarm is triggered, so you can see what set it off. On-demand photos need a PhOD model.
In the room
Door and motion sensors come in glossy black or white. Low profile, meant for finished trim and walls.

Room to grow
A Hub 2 Plus system is the same line for a home, shop, office, or ranch and for a large commercial building. We design the sensors, the areas, and the wireless coverage around the property.
Those are Ajax’s published figures for one Hub 2 Plus. The groups let a large building run different areas, instead of one switch for the whole property. Compatible range extenders connect back to that hub and give farther devices a path. They do not add device slots past 200, and one extender does not simply double the distance.
Wireless range is how far a sensor can talk, not how far it can see motion. In open space, with no obstacles, Ajax rates the link to the hub or a compatible range extender at up to 3,900 ft for DoorProtect Jeweller, up to 5,600 ft for MotionProtect Jeweller, and up to 5,550 ft for MotionCam Jeweller. MotionProtect and MotionCam detect motion out to 39 ft when mounted at 7.9 ft. Walls, metal, layout, and interference change the radio path, so we confirm coverage at the site check.
ReX extends Jeweller sensors. ReX 2 also carries MotionCam photos on Wings, and it can use Ethernet. The two extenders are not interchangeable for every device. One Hub 2 Plus is one system. A property that needs more than these limits is designed as separate systems. Commercial monitoring follows that design and an active monitoring agreement.
About Ajax Systems
Ajax Systems states its mission as standing against evil with technology that is innovative and still intuitive.
Its range also includes video, fire and life safety, and comfort devices that can share one interface. Nomad designs and installs the intrusion line: hubs, sensors, keypads, sirens, and the modules that tie a system to an older alarm.
The Ajax range
We design your system around your home, shop, office or ranch, then install and support it under our Texas DPS license. The same Hub 2 Plus can take motion, openings, the outdoors, water, air, and life safety.
Wide rooms, a narrow curtain across a window or hall, and a photo when a MotionCam alarms. Pet-tolerant models are part of the line.
Opening detection on doors and windows. DoorProtect Plus adds shock and tilt. GlassProtect listens for breaking glass.
Motion at the yard or the face of a building, and a curtain along a gate or fence line. StreetSiren sounds outside.
LeaksProtect notices water where it should not be. A WaterStop valve can shut the supply off. LifeQuality tracks temperature, humidity, and CO₂.
FireProtect 2 can watch for smoke, heat, and carbon monoxide on the same hub and in the same app.
Keypads at the door and sirens in the room. The Ajax app can arm the system from a phone. Scenarios can switch lights, locks, or water. Hardwired zones can come in through a MultiTransmitter, and many existing wireless sensors through a takeover module.
