Outdoor curtain detector Ajax 101441 — wireless, white, curtain-type motion sensor for outdoor perimeter protection

Ajax Outdoor Curtain Detector 101441 is a wireless, white curtain-type motion sensor designed for outdoor perimeter protection. The detector creates a narrow, elongated detection zone to monitor fences, windows, gates and other boundary lines. Intended for integration with Ajax security systems, it delivers targeted motion detection for outdoor installation and helps reduce false alarms by focusing on intrusion paths.

Advantages

The curtain-type design provides a focused detection beam up to 8–12 m, allowing precise monitoring of property boundaries. Wireless operation with two pre-installed CR123A batteries simplifies installation and eliminates the need for external power. Robust operating temperature range from −25 °C to +60 °C ensures reliable performance in varied climates. The compact white housing and included mounting accessories support flexible placement and quick commissioning.

How to use

Mount the detector on a stable surface oriented along the boundary to form a narrow detection beam. Use the SmartBracket and included angle mount or hood as needed to adjust coverage and protect the detector from direct exposure. Inserted batteries are pre-installed, so power is available immediately; verify connection with the Ajax system and perform a detection zone test. Adjust the detector position and angle to avoid vegetation or objects within the beam that may cause false triggers.

Recommendations

Install the detector at a consistent height and ensure the detection zone is free from obstructions. Regularly check battery status and perform periodic tests within the Ajax system to maintain reliable perimeter protection.
