The complete new portfolio of ADPRO PRO E-PIR Perimeter Intrusion Detectors (PID) was engineered to provide extraordinary reliability and accuracy. This new generation of PIRs evolved from the Xtralis defense-grade perimeter protection technology and our proven series of ADPRO PRO PIRs. Utilizing Passive Infrared (PIR) technology and combining it with precision mirror optics, employing the latest digital signal processing (DSP) and an environmental adaptive circuitry - this provides exceptional reliability of 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.
