ABSTRACT:
The decorative fixtures of the present invention enable azimuthal directivity of the infrared detector in order to adjust the directivity of the infrared detector about a vertical axis in a manner which is aesthetically compatible with the decorative nature of the fixture. In one embodiment, a hexagonal fixture is turnable about a horizontal axis to pivot not only the infrared detector, but the motion detection circuitry as well. In another embodiment, the motion detection circuitry and the infrared detector are physically separate within the decorative fixture, enabling the infrared detector to pivot within a circular portion of the decorative fixture.
