PIR Sensor

All Ajax motion detectors use PIR sensors by Excelitas Technologies — a field-leading American manufacturer specializing in designing and producing optronic components since 1931. Ajax Systems constantly proves the sensor’s Superior quality at the production stage: we test 100% of manufactured devices. Wrapped into Ajax technologies, it brings the utmost accuracy of intrusion detection

Thermal interferences 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.

Unique wired technologies

Fibra is proprietary Ajax 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.

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.

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.

Sabotage-resistant

Tamper alarm
The detector can be installed sideways. Its enclosure has three tamper buttons. Two of these are positioned on the rear side of the device, and they are triggered if the detector is removed from its mounting panel. The third tamper button is located at the bottom of the device and is triggered if someone attempts to break the lock securing the detector to its SmartBracket.

Anti-masking system
The detector is equipped with a masking sensor that prevents it from being discreetly disabled, even when the security system is disarmed. This sensor is designed to detect attempts to cover or block the detector using materials such as fabric, paper, metal, or even aerosols. Calibration can occur automatically when anti-masking is enabled or when the device is tampered with. It can also be started manually via a command in Ajax apps.

Protection against short circuits
If someone tries to create a short circuit, the system immediately notifies the monitoring station and users about the problem. There's no need to replace any fuse — once the issue is resolved, the detector automatically returns to normal operation.

Data encryption
All data the system stores and transmits is protected by block encryption with a dynamic key. This encryption not only makes it extremely difficult for intruders to reprogram the device but also provides robust protection against data replacement and theft.he system will restore operation automatically.

Device authentication against spoofing
During each communication session, the hub authenticates the device by checking its unique parameters. If any parameter fails the check, the hub ignores device commands.

Regular polling
The device regularly exchanges data with the hub. The system controls each device state and reports if there is a malfunction or connection loss.

Data-rich notifications
The Ajax system instantly delivers informative notifications about alarms and events. Security companies and users receive precise details about the incident, including the triggered device, along with the time and location.

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.
