A two-step approach for preventing false alarms
A street is constantly in motion: birds and animals move around, plants and bushes are warmed by the sun or sway in the wind, and numerous insects fall on the detector's body. Because of the variety of plants and animals present, outdoor motion detectors have a difficult time identifying the true threat, which is human activity. By integrating two PIR sensors and creating the unique two-step signal analysis method LISA, we were able to tackle this issue on both the software and hardware levels.
Correlational research
When MotionProtect Outdoor senses motion, LISA instantly examines and contrasts the data patterns from two different sensors. The alarm is set off if the forms are similar.
Spectral evaluation
LISA examines frequency components in the signals of the two sensors when they both detect motion, but the comparative analysis must find enough similarities to trigger an alarm.
