Active Infrared Sensor vs Passive Infrared Sensor in Perimeter Intrusion Detection Systems
Perimeter intrusion detection systems (PIDS) protect properties and sensitive areas from unauthorized access using various sensors. Infrared (IR) sensors, including Active Infrared Sensors (AIS) and Passive Infrared Sensors (PIS), are key in detecting motion and environmental changes. The distinctions, benefits, and applications of each kind in perimeter security are examined in this article.
