Bosch DS939 Panoramic PIR Motion Sensor Ceiling Mount, Range, 20' (6m)

Optimize your commercial security and surveillance with the Bosch DS939 Panoramic PIR motion sensor. This ceiling-mount PIR motion sensor delivers 360° panoramic coverage and effective detection out to 20' (6 m), providing consistent monitoring of lobbies, retail spaces, warehouses and corridors. Bosch engineered the DS939 with fully adjustable optics so integrators can customize detection zones and maintain coverage integrity at mounting heights up to 20' (6.1 m), reducing nuisance alarms and improving overall system reliability.

Installers benefit from a hinged chassis and base plate for faster mounting and wiring, plus a high-efficiency LED and light-pipe walk-test to speed commissioning. The detector’s wired connectivity and 9–15V DC power compatibility ensure a stable connection to alarm panels and access control systems. Patented First Step Processing (FSP) enhances detection sensitivity while minimizing false triggers — ideal for high-traffic commercial environments where accurate intrusion detection matters.

Add the Bosch DS939 to your next security upgrade for dependable motion detection and simplified installation — perfect for professional surveillance and monitoring projects.
