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: 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.

Anti-sabotage protection

Tampering alarm

Alerts of attempts to detach the detector from the surface or remove the mounting panel.

Protection against spoofing

device authentication

Anti-masking system

DualCurtain Outdoor Jeweller detects the following types of masking:

Obstacles in front of the detector's lenses at a distance of up to 10 centimeters (depends on the material).
Painting over the detector's lenses.
Taping the lenses or the detector's sides.

Lost connection detection

from 36 s

The time to detect the communication loss depends on the Jeweller (or Jeweller/Fibra) settings.

Power supply
