Dual Curtain Outdoor
Home Automation
Wireless bidirectional curtain IR motion detector
Principle of operation
The detector uses two narrow-angle PIR sensors to form two independent curtain-type detection zones. It detects movement by registering the temperature difference between a person and the background within these narrow sectors along the protected area.
Features
Allows simultaneous protection of both sides of windows, walls, passages, and facades. Curtain-type detection helps secure the perimeter without covering the entire area in front of the detector.
Installation and set up
The detector is ready to operate straight out of the box. The battery is pre-installed, and the device is mounted in a few minutes using the mounting bracket.

| Radio frequency band | 865.0–867.0 MHz |
| 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. Calculate radio communication range at the facility |
| Encrypted communication | All stored and transmitted data are protected by block encryption featuring a dynamic key. |
| Frequency hopping |
To prevent radio interference and jamming. Learn More |
| Detection | |
|---|---|
| Sensitive element |
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. Learn more |
| 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. Learn more |
| Sensitivity | 3 levels
Adjusted by a PRO or user with admin rights in the Ajax app. |
