Passive Infrared (PIR) sensors are a type of motion sensor that detects movement by measuring changes in the infrared (heat) levels emitted by objects. A Curtain PIR is a specialized PIR which is designed to create a narrow, vertical detection zone, resembling an invisible "curtain" or plane.
OPTEX PIRs have advanced features that offer superior detection with analytics that eliminate nuisance alarms to further improve their accuracy and reliability.
