Ajax: Five Motion Detector Models
Manufacturer and Lineup
The "Motion Detectors" section presents five Ajax models — a company founded in 2011 in Kyiv by Aleksandr Konotopskyi, which over more than a decade has become Europe's largest security-system manufacturer, protecting more than 4.5 million people across over 180 countries.
Five Detection Principles
The base MotionProtect model is a wireless infrared detector for indoor installation: mounted on the ceiling of an office, shop, bank, or apartment, it registers an intrusion within seconds and instantly sends a push notification to the owner's app.
MotionProtect Curtain uses a different detection principle — a "curtain": instead of a wide viewing cone, the detector forms a narrow vertical sensitivity zone, ideal for guarding a specific opening — a window, doorway, or passage between rooms — where a wide viewing angle would cause unnecessary triggers from movement outside the controlled zone.
MotionProtect Outdoor is adapted for outdoor installation: protection against precipitation and direct sunlight, along with special filtering algorithms that distinguish human movement from swaying tree branches or cloud shadows — a common cause of false triggers in cheaper manufacturers' outdoor detectors.
DualCurtain Outdoor ("double curtain") is an exclusive solution for outdoor perimeter protection: two independent motion-detection beams allow precise monitoring of a narrow strip of territory, such as along a fence or building wall, with minimal risk of false alarms from objects outside the controlled zone.
MotionProtect Plus is the lineup's most advanced model, combining an infrared sensor with a K-band microwave sensor: the detector confirms an alarm only when both sensors register motion simultaneously, significantly reducing the chance of a false trigger from a draft, a pet, or direct sunlight, which can mislead purely infrared models.
Technology Advantages and Choosing a Model
Every wireless detector in the lineup runs on Ajax's own Jeweller protocol, developed in-house — a solution that optimizes power consumption to run on a single battery for years without replacement and ensures the connection resists jamming attempts by intruders.
Ajax systems built on these detectors became the world's first wireless security system certified to the European EN 50131 standard's highest tier, Grade 3 — a mandatory requirement for sites with elevated security standards, where every system component's reliability must be confirmed by independent certification.
Detection range and viewing angle vary by model, so before installation it's worth checking the specific detector's technical documentation against the actual geometry of the room or area — insufficient coverage of the viewing angle leaves a "blind zone," while excessive coverage catches territory beyond the controlled site.
The detectors' housings are designed with modern interior aesthetics in mind — MotionProtect's compact white housing blends unobtrusively into an office or apartment ceiling, while outdoor models have a more rugged, functional design oriented toward weather resistance rather than decoration.
Choosing a specific model mainly comes down to installation location and the controlled zone's geometry: MotionProtect for a standard room, MotionProtect Curtain for a narrow opening, MotionProtect Plus for rooms with elevated false-alarm risk, and the Outdoor models strictly for outdoor use.
Choosing specifically within the "Motion Detectors" section means comparing Ajax's products against other security-system manufacturers featured here on practical criteria: detection type (PIR, curtain, dual-technology), installation location (indoor or outdoor), and compatibility with an existing security-system hub.
