Abstract

A wireless camera fixture adapted to mount on a track, such as a track normally used for overhead lighting fixtures, is described. Embodiments include the use of IEEE 802.11 wireless protocol, the use of a standard track-mount power supply; the use of a two-axis tilt and pan mechanical mount; hardware to permit horizon correction; modifications to a camera enclosure to support an antenna inside the enclosure and access to camera controls; use of multiple antennas; use of a cover plate at the front of the enclosure; use of visible light or infrared light LEDs on the cover plate; configuration to use dual-circuit tracks; use of separate circuits in the track to power the visible light and infrared light LEDs separately. A method of manufacturing the fixture is described.

Claims

1. A wireless camera fixture comprising:

a mechanical base adapted to mount in a track, wherein the track is adapted to provide power and mechanical support for at least one track-mounted lighting fixture;

a mechanical enclosure, attached movably to the base;

a video camera, located in the enclosure, powered via the base; and

a wireless module, electrically connected to the video camera, adapted to transmit video data from the camera via a wireless protocol;

wherein the base is a regulatory agency approved power supply for use with a track and a track-mountable light fixture;

one or more visible light LEDs that project light generally along the optical axis of the video camera;

one or more infrared (IR) light LEDs that project light generally along the optical axis of the video camera; and

wherein the visible light LEDs are adapted to be powered from a first track circuit and the IR LEDs are adapted to be powered from a second track circuit.

2. The wireless camera fixture of claim 1 wherein:

the enclosure is adapted to accept one of a plurality of removable cover plates and wherein at least one cover plate provides illumination elements suitable to illuminate a scene visible by the video camera.

4. The wireless camera fixture of claim 1, further comprising:

a second power supply, located inside the enclosure, whose input power comes from the base and whose output power goes to the video camera.

3. A wireless camera fixture comprising:

a mechanical base adapted to mount in a track, wherein the track is adapted to provide power and mechanical support for at least one track-mounted lighting fixture;

a mechanical enclosure, attached movably to the base;

a video camera, located in the enclosure, powered via the base; and

a wireless module, electrically connected to the video camera, adapted to transmit video data from the camera via a wireless protocol;

a rotatable mechanical joint such that the video camera may be rotated around its optical axis;

wherein the rotatable mechanical joint also mounts the video camera in the enclosure;

wherein one or more visible light LEDs that project light generally along the optical axis of the video camera;

one or more infrared (IR) light LEDs that project light generally along the optical axis of the video camera; and

wherein the visible light LEDs are adapted to be powered from a first track circuit and the IR LEDs are adapted to be powered from a second track circuit.
