COMPOUND-EYE CRIME PREVENTION SENSOR SYSTEM

摘要

A compound-eye crime prevention sensor system which can securely discriminate a human being from a small animal regardless of the distance from a detector. The system includes a zone-to-zone distance changing means such that the distance theta L between a detection zone A and a detection zone B of a detector 1 when the zones A, B are at the furthest position L in the invading object detection range is smaller than the distance theta S between the zones A, B when the optical unit in the detector 1 is rotated and the zones A, B are shifted to the position S under the detector 1.
