PIRAMID XL2 is a dual technology volumetric intrusion detector which integrates a high-frequency proprietary technology (Doppler stereo) and passive infrared. These two technologies of the detector must be enabled simultaneously to generate an alarm. A proprietary integrated circuit offers advanced signal processing for each of the two technologies, thus offering immunity against disturbances caused by birds and small animals. PIRAMID XL2 detectors are unique in this respect; they offer a reliable volumetric protection, even in extremely difficult environmental conditions.
