Smart false alarm filter
MotionCam Outdoor has two separate PIR sensors, and a two-step LISA algorithm is used to analyse their data. When both sensors detect motion, LISA correlates and analyses the signals to quickly discern between genuine threats and interference.
Correlational research
When MotionCam 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 correlational analysis fails to find enough similarities.
