Abstract:
1. Apparatus for detecting intrusion into a space, said apparatus including, in combination: motion detection light structure for simultaneously producing a plurality of light beams having different lengths and solid conic configurations and for projecting said light beams into said space, said projected plurality of light beams including a conic first light beam configuration having a longitudinal axis and a conic second light beam completely surrounding said first light beam immediately adjacent to said motion detection light structure, said motion detection light structure including a light source and a reflector structure operatively associated with said light source to project said plurality of light beams into said space with the first light beam being an elongated light beam extending a first distance from said motion detection light structure into said space when not interrupted by an object in said space and the second light beam extending a second distance from said motion detection light structure into said space when not interrupted by an object in said space, said second distance being less than said first distance whereby said first light beam is completely embedded in said second light beam immediately adjacent to said motion detection light structure; and video motion detecting structure including a video camera having a field of view including at least some of said light beams produced by said motion detection light structure to detect intrusion into said space.
