ADPRO PRO E-PIR Perimeter intrusion detectors (PID) are engineered to provide extraordinary reliability and accuracy. This generation of PIRs evolved from the Xtralis defense-grade perimeter protection technology and the proven series of ADPRO PRO PIRs. They utilize passive infrared (PIR) technology, combined with precision mirror optics, and employ the latest digital signal processing (DSP) along with environmental adaptive circuitry to provide exceptional reliability in detection while minimizing nuisance alarms. ADPRO PRO E-Series detectors achieve unsurpassed performance even under precarious environmental conditions. The ADPRO PRO E-Series PIR detectors are available in a variety of models to optimally address your perimeter, performance, and budget needs.
