PIR sensor
All Ajax motion detectors use PIR sensors by Excelitas Technologies — a field-leading American manufacturer which specializes 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, the sensors bring the utmost accuracy of intrusion detection.
K-band microwave sensor
The K-band microwave sensor scans a room to minimize false alarms triggered by thermal interferences. Operating in conjunction with the PIR sensor, it uses microwave technology only for PIR sensor alarm verification. Unlike traditional X-band sensors, the K-band sensor offers superior energy efficiency and enhanced precision, resulting in significantly fewer false alarms. Additionally, the sensor is entirely safe and poses no harm to human health.

Special lens
The pattern of the Fresnel lens sections is designed to differentiate between the IR diagrams of a human, animal, and thermal noise. Large lens sections capture radiation at an adult's head and torso level. Smaller sections make the diagram more detailed. The lens provides the detector with accurate information about the thermal object in the detection zone and the nature of its movement.
Thermal interferences filter
We processed thousands of thermal patterns caused by humans, animals, and the environment to develop the SmartDetect software algorithm. In armed mode, the detector constantly analyzes the thermal diagram from the PIR sensor, including the IR radiation intensity, thermal spot size, movement speed, time spent in the detection zone, and other parameters. The algorithm identifies false alarm markers instantly and with high accuracy. As a result, the detector accurately responds to human movement without false alarms.

Temperature compensation
Temperature compensation is a software mechanism keeping the thermal diagram contrast even if the ambient temperature is close to the temperature of the human body. With each ambient temperature measurement, the detector corrects the PIR sensor data according to the coefficient table stored in its memory. The detector is effective over the entire operating temperature range.
Sensitivity level
The detector can adapt to the conditions of a particular facility, considering possible thermal interference or pets. The sensitivity setting changes the set of markers by which false alarms are filtered. Low sensitivity makes the detector less likely to respond to an active pet. A high sensitivity will raise the alarm in case of any movement in the detection zone.
Professional installation
With the correct installation at the height of 2.4 m and lens direction perpendicular to an alleged intrusion path, the detector provides an accurate thermal diagram and pet immunity. It instantly responds to a real threat, minimizing false alarms caused by animals weighing up to 20 kg and below 50 cm in height.
Fibra
Unique wired technologies
The Ajax system uses secure two-way communication based on the Fibra proprietary protocol. It features block encryption and device authentication to prevent sabotage, spoofing, or data theft. Fibra lines are multifunctional and support connecting different types of devices to one line: sirens, keypads, and detectors with photo verification.
Up to 2,000 m of wired communication with a hub or a module that extends the Fibra line2
One line for different types of devices
Photo delivery by the Fibra line without interference
Protection against sabotage and spoofing
Energy efficiency as a priority
Fibra communication requires minimum power consumption, with the detector consuming only up to 0.086 W at its peak. This low power consumption allows installers to connect multiple devices to a single Fibra line, extending wired connectivity.
Fibra operates on the TDMA principle. Each device has a short time frame to exchange data with a hub, and its communication module remains inactive the rest of the time. This significantly reduces power consumption and helps avoid interferences even when multiple devices communicate simultaneously.
TDMA and power-saving modes
Power consumption of up to 0.086 W
System supervision
All Ajax devices perform automatic self-diagnosis and report their states to the hub. Essential parameters, including tamper, communication, power supply, and sensor statuses, are continuously monitored. The Ajax Cloud server controls communication between the hub and Ajax apps, ensuring instant notifications for ARCs, security companies, and users. In case of any malfunction or communication failure, an engineer is informed immediately to provide necessary services.

Technical information
MotionProtect Plus Fibra
Ajax product lines
Superior, Fibra, and Baseline product lines are mutually compatible. This opens up numerous possibilities for building systems of any configuration.
Security wired motion sensors for the premises
To protect the building from intrusions, motion sensors are used. Motion detectors differ in the way a person's movement is detected, which is based on the principles:- infrared radiation;
- radio wave action;
- ultrasonic and sonic action.
- Temperature characteristics determine the scope and performance of the sensor in ambient conditions. It is necessary to pay attention to the ability of the sensor to work at an air temperature close to the temperature of the human body to avoid false positives.
- Supply voltage.
- Consumed current.
- Type of relay contacts used (normally closed NC, normally open NO).
- Immunity to animal movements.
Features and applications of infrared motion sensors
The principle of operation of IR motion sensors is to receive infrared radiation from objects in the protected area. All material objects (humans, animals, furniture) radiate heat. The motion sensor receiver detects the change in thermal radiation, and the detector decides on the appearance of a foreign object. Features of mounting IR motion sensors:- Avoid pointing the detector at sources of sunlight and heat to avoid false alarms.
- For volumetric characteristics, the installation of IR motion sensors should be carried out in the same way as radio wave ones.
Features and application of radio wave motion sensors
The principle of operation of radio wave motion sensors is to reflect electromagnetic waves from an object. The device's sensor is equipped with an electrical oscillation generator that constantly emits energy. When a person appears in the detection field, the electrical oscillations change, and the receiving part captures the change in the waves. After that, the presence of a person is confirmed. Installation of radio wave motion sensors is carried out following the parameters of the field of action:- Sensors with a field of action of 90° or less are mounted in the corner of the room or on the wall, depending on the direction of the object of protection.
- Motion sensors with a field of 180° are mounted on the wall.
- Detectors with a 360° field of action are installed in the center of the room on the ceiling.
Features and Applications of Ultrasonic Motion Sensors
The principle of operation of ultrasonic type motion sensors is based on changing the oscillations of ultrasonic waves that a person does not perceive, reflected from objects, and their registration using the Doppler effect. When the reflected wavelength changes, the motion detector is triggered. Ultrasonic motion sensors are insensitive to thermal changes and have a narrow field of view up to 60°. Installation of ultrasonic motion sensors is reasonable in the corner of the room or on the wall. Such detectors are often used in small, narrow spaces.MotionProtect Plus Fibra — indoor wired motion sensor
The MotionProtect Plus Fibra wired motion sensor detects motion at a distance of up to 12 meters and is designed for indoor installation under guard. MotionProtect Plus Fibra communicates with the control panel using the secure Fibra protocol at a distance of up to 2000 meters when connected via a U/UTP cat. 5 twisted pair cable. After detecting motion in the armed mode, the motion sensor immediately transmits an alarm signal to the alarm control panel. The control panel, in turn, launches scenarios, notifies users and the security company about the incident, and activates the security sirens. MotionProtect Plus Fibra from Ajax is compatible with Hub Hybrid alarm control panel. Connection to other control panels, radio signal repeaters, ocBridge Plus and uartBridge is not provided. The MotionProtect Plus Fibra wired motion sensor is available in two colours: white and black. Due to the variability of colours and laconic design, the device is easy to integrate into any kind of interior.How the MotionProtect Plus wired motion sensor works
Indoor wired motion sensor MotionProtect Plus Fibra is equipped with an additional microwave sensor. With the help of an IR sensor, it detects an intrusion when it notices the movements of objects with a temperature close to the temperature of the human body. When the MotionProtect Plus Fibra wired motion detector detects motion, it performs an RF scan of the guarded area to eliminate false alarms due to thermal noise. This principle of operation of the device helps distinguish between thermal interference created by fans, air conditioning, air flow, etc.Features of MotionProtect Plus wired motion sensor
MotionProtect Plus Fibra wired motion detector with microwave sensor is used indoors for perimeter protection and has several advantages:- Thanks to its advanced detection system, the motion sensor provides accurate motion detection even under challenging environments. The MotionProtect Plus microwave sensor is only activated when the infrared sensor detects movement. It is possible to provide reliable protection in rooms with thermal interference: fireplaces, drafts, and air conditioners.
- The MotionProtect Plus Fibra, a wired motion sensor, ignores the movements of animals weighing up to 20 kilograms and high up to 50 centimetres.
- Each event recorded by the MotionProtect Plus Fibra wired motion sensor is recorded in the notification feed of the Ajax application. And also, the owner always knows exactly where the movement of an outsider was noticed, thanks to the targeting of motion detectors. The alarm message contains the name of the activated device, the name of the protected object and the virtual room to which the sensor is assigned.
- MotionProtect Plus Fibra is a wired device from Ajax that requires professional installation. The installer must be trained and accredited for acquisition, installation, and administration.
