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 enhanced precision and superior energy efficiency. This results in minimal impact on battery life and significantly fewer false alarms. Additionally, the sensor is entirely safe, posing 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.

Motion sensor for security alarm Ajax MotionProtect Plus with microwave sensor
The presence detector is often installed to turn on the lighting when a person enters the controlled area and turn it off when they leave. The device helps to save electricity and eliminates the need to turn on the light mechanically. Motion sensors are also used for installation in burglar alarm systems. The device detects intruders' attempts to enter the premises. In addition, motion sensors are also used on production lines to automate the execution of technological tasks.Types of presence detectorsPresence sensors are distinguished by the principle of operation on which their accuracy of the process and the features of use and installation depend. The price of motion sensors depends on the design and type of element used.
Contact motion sensors for signallingThe essence of this type of motion sensor is to install a reed switch on the door. A reed switch (sealed contact) is a switch that work when a magnetic field appears. When a person opens the door and enters the room, the contacts will close. The alarm control panel will receive the incident signal, and the lighting or siren will be activated.
Infrared motion detectorsInfrared motion sensors are triggered by thermal radiation and react to changes in the temperature in the room. When an object enters the field of view of such a detector, it will respond to the thermal radiation that comes from the body. A PIR sensor is used as a sensitive element of the device, which creates an electric field proportional to thermal radiation.
Ultrasonic presence sensorsThe ultrasonic motion sensor operates at high frequencies from 20 kHz to 60 kHz. The negative feature of this sensor is its irritation with the frequencies of animals that are sensitive to them. Ultrasonic presence sensors work on the Doppler effect. The sensor wave reflected from the moving object is returned and received by the receiver. In this case, the frequency of the wave changes slightly. This is detected, and the detector sends a signal to the control panel.
Photosensors or laser motion sensorsLaser motion sensors have an emitter, an infrared LED, and a receiver, a photodiode of the same spectrum. This is a simple detector, the implementation of which is possible in two versions:
- The emitter and the photodiode are installed next to each other. When the object is in the detector's coverage area, its radiation is reflected and falls on the photodiode. Such a device is also called an obstacle sensor and is often used in robotics.
- The photodiode and the emitter are installed in the protected area opposite each other. When an object passes through it, it obscures the radiation, and it does not reach the receiver, after which the motion sensor is triggered, and the relay is turned on — used in alarm systems.
Microwave presence detector
The microwave motion sensor consists of a transmitter and a receiver. The first generates high-frequency signals, and the second receives them. When an object passes nearby, the frequency changes. When the frequency changes, the signal is amplified and transmitted to the alarm relay, and the load is turned on. Microwave sensors are susceptible and allow you to detect movements even behind a door or behind glass. They react even to the most accurate movements and are often used in burglar alarm systems.ConclusionThe use of motion detectors helps save energy and resources for lighting devices. This is a step towards the smart home and routine automation. Also, a motion sensor is an indispensable element of a security system that will help prevent intrusion into a protected area, theft and damage to property, respectively.
