LISA intelligent algorithm for false alarm prevention.
LISA turns MotionProtect Outdoor into a formidable barrier for intruders. The digital algorithm accurately identifies the movement of a person while ignoring animals, swaying of trees and plants as well as birds and insects that land on the detector.
LISA analyses the similarity of signals originating from two sensors in two stages. If the signals appear similar during the first stage but the detected similarity is insufficient to trigger an alarm, the comparison of the spectral components is initiated. It helps to ignore trees swaying in the detector’s field of vision.
* The detector ignores bushes up to 80 cm high and trees whose crowns cross only the upper beam
