Optex AP-20NB(C) Indoor Recessed Mount Wired Curtain PIR Detector

Keep critical indoor zones monitored with the Optex AP-20NB(C) indoor recessed curtain PIR detector — engineered to deliver targeted, reliable motion detection without drawing attention. This Optex PIR motion sensor provides a 20 ft (6 m) curtain detection pattern ideal for narrow aisles, storefront windows, server room access points and perimeter corridors. The compact recessed housing supports both ceiling and wall mounting (typical ceiling coverage at 14'9" and wall mounting at 4'11"), allowing integrators to tailor coverage to the space while maintaining a low visual profile. Wired connectivity delivers stable, tamper-resistant performance and straightforward integration into security panels, access control and surveillance monitoring systems. By focusing detection into a narrow plane, the AP-20NB(C) minimizes false alarms from peripheral activity and improves event accuracy for surveillance and alarm workflows. Choose this detector when you need precise, professional-grade motion sensing for retail, commercial and institutional applications. Contact sales or add the AP-20NB(C) to your next security deployment for dependable curtain detection and seamless system integration.
