Wired curtain detector from the QTech series, featuring dual infrared and microwave technology, anti-masking function, 3-meter coverage and 70° detection angle for indoor applications
Advanced perimeter protection
The QDT500H wired curtain detector from the QTech line uses dual infrared and microwave technology to deliver precise protection for indoor environments. With a 3-meter curtain detection range and a 70° angle, it is ideal for monitoring access points such as doors and windows, ensuring targeted intrusion detection.
Reliable performance and smart functionality
The QDT500H offers advanced features such as digital signal analysis, programmable sensitivity, and automatic temperature compensation. The “AND” and “Smart-OR” operating modes ensure accurate alarm reporting: the former requires simultaneous detection by both sensors, while the latter triggers an alarm even in the case of prolonged detection by a single sensor.
