Spirit-DUAL is a motion detector that uses a dual passive pyroelement and k-band microwave to detect an intruder. The infrared detector features 3D Fresnel lens technology. The 3D lens has 52 detection zones, thanks to which it provides full coverage with no dead angle and no possibility of approaching from below. The maximum detection range is 12 m. Thanks to the use of advanced IFT technology, the detector automatically adjusts the alarm triggering thresholds when electromagnetic or electrical interference is detected, minimizing the risk of false alarms. The functions of digital temperature compensation and automatic sensitivity make the detector adapt itself to changing environmental conditions to maintain stability and effective detection of intruders.
The combination of two detection technologies, i.e. infrared and microwave, allows you to minimize the number of false alarms, even in unstable operating conditions. The Spirit-DUAL detector is perfect for rooms with additional heat sources, for example rooms equipped with a fireplace, sources of ventilation, air conditioning, etc.
