IN PROGRESS
When high security meets high tech
Superior MotionProtect G3 Fibra is an indoor motion detector designed primarily for high-risk facilities. It offers precise motion detection at a distance of up to 49 ft and responds to both slow and fast movements. The blind zone is just 1.6 ft, ensuring that an intruder's attempt to crawl under the device will be detected immediately. The anti-masking system notifies of attempts to cover, obstruct, or paint the device’s lens. Superior MotionProtect G3 Fibra can be quickly installed at any site that requires accurate intrusion detection, reliable sabotage protection, and an effective false alarm filter.
In an Ajax system, you can combine devices of all product categories: Intrusion protection (both Superior and Baseline), Video surveillance, Fire and life safety, or Comfort and automation. Create the system to suit your needs and manage it in a single interface.
Only accredited partners who have passed specialized training can sell, install, and administer Superior devices.

PIR sensor
All Ajax motion detectors use PIR sensors made by Excelitas Technologies, a respected American company making high-quality optical and electronic components since 1931. Ajax Systems tests every single device produced to ensure it works perfectly. This testing helps guarantee that the detectors can accurately spot any intruders.

Thermal interference filter
SmartDetect is a software algorithm developed after analyzing thousands of thermal patterns from people and environmental objects. When the motion detector is in armed mode, it constantly monitors heat data from a PIR sensor. This includes details like the intensity of infrared radiation, the size of the warm object, how fast it’s moving, how long it stays in the detection area, and more. The algorithm uses this information to instantly and accurately filter out heat sources like headlights, lighting equipment, or warm air currents. As a result, the detector reacts to real movement while avoiding false alarms.

Temperature compensation
Temperature compensation is a software feature used in Superior MotionProtect G3 Fibra. It helps the device keep working accurately even when the surrounding (ambient) temperature is similar to the human body temperature. The detector constantly measures the ambient temperature and uses a built-in correction table to correct the PIR sensor data.

Professional installation
Superior MotionProtect G3 Fibra works best when it is installed and configured correctly. This involves mounting the device at the proper height and angle to ensure it monitors the intended area effectively. Correct positioning helps eliminate blind spots and improves detection accuracy. Proper installation also reduces false alarms, by avoiding areas with fluctuating temperatures or frequent non-threatening movements.




Masking detection
Even if the Ajax system is disarmed, an intruder cannot sabotage the device without being noticed. The detector’s anti-masking system notifies of attempts to cover, obstruct, or paint the lens. It detects all masking materials, including drapery, paper, metal, glass, plastic, aerosols, dyes, and more.

Superior MotionProtect G3 Fibra does not have a pet immunity feature.
Fibra
Unique wired technology
Fibra is Ajax’s proprietary technology for secure two-way communication between devices and a hub or module that extends the Fibra line. Fibra features encryption and device authentication to prevent sabotage, spoofing, and data theft. The Fibra line supports all types of devices, including sirens, keypads, and detectors with photo verification.

Communication range of up to 6,550 ft
One Fibra line for different device types
Photo delivery via Fibra line without interference
Protection against sabotage and spoofing
Energy efficiency as a priority
Fibra communication requires minimum power consumption. Even at its peak, Superior MotionProtect G3 Fibra uses only up to 0.23 W. Fibra operates on the TDMA principle, where each device is assigned a brief time slot to exchange data with the hub. Outside of this slot, the device’s communication module stays inactive. This approach greatly reduces energy use and prevents interference, even when many devices are operating at the same time.

Power consumption of up to 0.23 W

System supervision
Superior MotionProtect G3 Fibra has a self-test function that checks whether its sensors work properly. Specifically, it tests the PIR sensor and the masking sensor. Ajax runs the self-test automatically at regular intervals and sends an immediate notification if there's any problem or malfunction. Users can also manually start the self-test at any time using the Ajax apps.

PRO is king
Ajax busts the myth that wired systems are hard to install. Fibra technology transforms what was once an expensive, lengthy, and messy process into one that is easy and flexible — from project design to client support and system maintenance. Superior MotionProtect G3 Fibra doesn't need to be disassembled during installation, and the intuitive Ajax apps make it easy to add the detector to the system. It can be reconfigured remotely at any time — everything works straight out of the box.
Fibra power supply calculator
This online tool provides security engineers with detailed data on devices’ power consumption, enabling easy pre-installation assessment of a wired system project. The calculator helps design the project in real time, highlights problem spots, and offers solutions. Results can be downloaded as a PDF file.
An installer can easily mount Superior MotionProtect G3 Fibra on the wall using the SmartBracket panel. The installation kit includes all the necessary fasteners. There is no need to disassemble the device: the board with terminals is placed outside the enclosure under SmartBracket to eliminate hardware damage during installation. The board is removable, which makes the whole process more comfortable. For cable management, there are fasteners inside SmartBracket to secure the wires with ties.

The device is paired with a hub automatically via Fibra line scanning. This feature is available in the Ajax PRO Desktop app and Ajax PRO: Tool for Engineers mobile app. Also, there is an option to scan the device QR code or enter the ID to pair with a hub. After that, all the installer has to do is to assign a name, room, and security group to the device.

Accounts for companies and installers

An Ajax system transmits alarms to the Ajax PRO Desktop app or any third-party CMS. A monitoring company receives alarm notifications in less than a second. They include all the necessary information: the device name, event time, and the exact room where the device is installed. A monitoring company also receives photo or video verification of the alarm to understand what caused it.
