Radionix DS936 Low-Profile Ceiling-Mount PIR Detector

Mount PIR motion detection at the ceiling with a low-profile sensor housing suited to physical security installations. Passive infrared sensing detects changes in infrared energy associated with movement, making the detector appropriate for monitored interior areas where an overhead detection point is required. The ceiling-mount format keeps the sensing device positioned above the protected space rather than on a wall surface. The DS936 fits security system designs that call for a ceiling-installed PIR detector without a prominent wall-mounted enclosure. Its low-profile construction helps maintain a less conspicuous installed appearance in offices, corridors, reception spaces, and other interior environments where detector visibility matters. Ceiling placement can also support layouts where wall space is occupied by doors, windows, equipment, displays, or architectural finishes. This specific model is defined by its combination of PIR sensing, low-profile construction, and ceiling-mount orientation. Those attributes distinguish it from detectors intended for wall installation or applications that require another sensing method. Specify the detector where the system design calls for overhead passive infrared motion detection and where the mounting surface and finished appearance support a low-profile ceiling device.
