The PIRAMID XL2 outdoor intrusion sensor combines Stereo Doppler Microwave and Passive Infrared technologies whereby both technologies must activate simultaneously to create an alarm. The Stereo Doppler Microwave portion activates upon the movement of an intruder and the Passive Infrared portion activates on the change in infrared radiation caused by the intruder.

The PIRAMID XL2 outdoor sensor was designed to satisfy medium level security requirements as well as environmentally challenging applications. Using the unique combination of Stereo Doppler Microwave and Passive Infrared increases detection sensitivity while providing unequalled false-alarm-free performance.
