A system for detecting intrusion into a space which includes motion detection light structure for producing and projecting a light pattern formed by a plurality of light beams of a certain character into a space and video motion detecting structure including a video camera having a field of view including at least some of the light pattern to detect intrusion into the light pattern. When motion is detected, images of the video camera are transmitted for threat assessment, and a scene illumination light is activated to improve visibility during nighttime operation.
