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.

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, pet, 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, pets, 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 motion without false alarms.

Temperature compensation

Temperature compensation is a software mechanism that keeps 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 motion in the detection zone.

Professional installation

With the correct installation at a 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 pets weighing up to 20 kg and below 50 cm in height.

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

The Fibra communication requires minimum power consumption, with the detector consuming only up to 0.045 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 for exchanging 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.

System supervision

All Ajax devices perform automatic self-diagnosis and report their states to the hub. Essential parameters, such as a tamper state, 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.

Tamper alarm
The enclosure is hardwired with a tamper button, which notifies the security company and users once the detector is dismantled from the mounting panel or when it is detached from the surface.

Short circuit protection
The system instantly detects a short circuit on the line and notifies the security company and users. And when the problem is fixed, there is no need to replace fuses: the system will restore operation automatically.

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

The myth about wired systems being difficult to install is busted. Ajax minimized an expensive, long, and dusty experience for PROs by developing an ultimate set of tools to make the process easy and flexible, from project design to client support and system maintenance. There is no need to disassemble the device for installation. Intuitive Ajax apps help quickly make the device a part of the system, and each device can be reconfigured remotely at any moment. No programming required — everything is available out of the box.
