Ajax Wireless IR indoor motion detector

A key element for intelligent security

Motion detectors form the core of security systems. Recognizing their pivotal role, we created MotionProtect Jeweller — a misleadingly simple yet powerful motion detector for optimal reliability and ease of use. Its cutting-edge hardware and software algorithms reduce the amount of false alarms to almost zero. With a sleek design, detectors are seamlessly integrated into any space. Installation is simplified with wireless capabilities and the SmartBracket mounting panel, while remote configuration eliminates the need for on-site visits to solve minor requests.

No intruder goes unnoticed

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.

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.

SmartDetect

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.

 

Thermal spot size		Movement speed		IR radiation intensity
False alarm	Real alarm	False alarm	Real alarm	False alarm	Real alarm

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 object, 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.

Wire-free flexibility and reliable performance

Baseline devices operate without any wires, offering maximum flexibility during installation. The pre-installed CR123A batteries from proven manufacturers ensure hassle-free setup, requiring no additional steps to start operating the devices. In addition to real-time testing during battery production, Ajax Systems inspects every unit to ensure the accuracy of the batteries’ characteristics. The batteries are easily replaceable, allowing one to swap them out after approximately five years of autonomous operation. The battery status is always accessible via the Ajax app. Users and security companies receive low battery level warnings months in advance, allowing for timely replacement without rushing.

 

• Real-time testing during battery production
• Up to 5 years of autonomous operation
• Low battery level notification in advance

 

Jeweller

Unique wireless technology

The Ajax system uses secure two-way radio communication based on the Jeweller proprietary protocol. It supports block encryption and device authentication on every session with the hub to prevent sabotage, spoofing, and data theft.

The Ajax wireless technology has a radio communication range of up to 1,700 m in an open space, which is, on average, longer than that of competing solutions. Automatic power adjustment ensures energy efficiency by avoiding constant use of maximum power in system devices’ radio transmitters. Also, the Jeweller technology is more stable due to using less noisy radio frequencies. Ajax hubs use frequency hopping to protect against radio interference and signal interception. The system automatically changes frequency within a band and notifies the security company and users about jamming.

 

Jeweller uses polling to display the real-time device status and transmits alarms, events, and all measured readings into Ajax apps. Features encryption and authentication to prevent spoofing.

 

• Up to 1,700 m of radio communication with a hub or range extender¹
• Encrypted two-way radio communication
• Notifications about jamming and connection loss

 

Scaled and comprehensive

ReX 2 Jeweller boosts the radio communication range of all Ajax devices via Jeweller. It guarantees stable communication even through steel and concrete via Ethernet using the wire as the additional communication channel. Up to 5 range extenders can operate within one Ajax system to expand the network twice as big, covering areas like underground parking, basement, or metal hangar.

 

• Up to 5 range extenders within one system
• Ethernet as an alternative communication channel
• Big estate and large facilities
• Business center with underground parking
• Warehouse or industrial complex
• Sectional metal hangar

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.

 

• Automatic device self-diagnosis with a state report
• Regular polling to display the current device state on apps
• Instant maintenance notifications

 

Sabotage resistance

 

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.	Data encryption   All data the system stores and transmits are 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.	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.
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 any malfunction or communication loss.	Communication loss detection   At minimal polling interval settings (3 data packages every 12 seconds), it takes only 36 seconds to detect communication loss and notify the security company and users about the incident.

 

Effortless installation and setup

MotionProtect Jeweller is ready to operate straight out of the box. Using the SmartBracket mounting panel, an installer can effortlessly mount the device on the wall, eliminating the need to disassemble the enclosure. Ajax apps facilitate quick integration into the ecosystem: simply pair the device with the hub by scanning the QR code. It can always be reconfigured remotely without the need for on-site visits.
