Radio frequency bands
866.0–866.5 MHz
868.0–868.6 MHz
868.7–869.2 MHz
905.0–926.5 MHz
915.85–926.5 MHz

Depends on the region of sale.
Maximum effective radiated power (ERP)
up to 20 mW
Automatic power control to reduce power consumption and radio interference.
Radio signal modulation
GFSK
Radio communication range
up to 1,700 m
Between the detector and a hub (or radio signal range extender) in an open space.
Encrypted communication
All the data stored and transmitted are protected by block encryption with a floating key.
Frequency hopping
To prevent radio interference and jamming.
Detection
Sensitive elements
4 × IR sensor
Motion detection distance
4–15 m for each side
When installed at a height of 0.8 to 1.3 m. Adjusted separately for each side using sliders on the detector rear panel.
Viewing angles
horizontal — 4.5°
vertical — 90°
Motion detection speed
0.3 to 2.0 m/s
The direction of the detector lens should be perpendicular to the intended path of entry into the facility.
Near zone detection
When enabled, the detector’s upper IR sensor receives an additional sector of view, directed at an angle of 40° downward of the main sector.
This is necessary to detect motion near the detector and reduce blind spot.
Adjusted separately for each side using sliders on the detector rear panel.
Viewing angle shift
When enabled, the optical system viewing angle can be shifted by 3° in the horizontal plane.
Adjusted separately for each side using sliders on the detector rear panel.
Sensitivity
3 levels
Adjusted by a PRO or user with admin rights in the Ajax app.
Pet immunity
height:Â up to 80 cm
weight: irrelevant
Protection from false alarms
SmartDetect
ELSA
Software algorithms.
Temperature compensation
Effective motion detection at temperatures from -25°C to +60°C.
Recommendations
The detector is installed at a height of 0.8–1.3 meters from ground level when used to protect doors, arches, other passages, or the area in front of windows. Otherwise, if the detector is used to protect windows, it is installed at a height of 0.5–0.6 meters from the window sill.
