Title:
COMPOUND-EYE TYPE CRIME PREVENTION SENSOR SYSTEM
Document Type and Number:
Japanese Patent JP2016001424
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a compound-eye type crime prevention sensor system, in which detection zones arranged along an entry direction of an object to be detected are disposed on two lower and upper stages, capable of arranging expansion between the detection zones on a position where prefer balance of identification for detecting human being and not detecting small animals is achieved at respective installation height and alert distance, with high reliability.SOLUTION: A compound-eye type crime prevention sensor system comprises: detection zone interval change means for changing an interval between detection zones on upper and lower stages to become larger, following to change of a direction where the detection zones extend, downward from a state which is set for detecting human being who passes through a farthest point of an entry object detection range, and the detection zone interval change means changes the interval between the detection zones on upper and lower stages to become smaller when the installation height of the sensor is set to a high position.
