Perimeter intrusion detection system and method

Abstract

The invention relates to a perimeter intrusion detection system. The perimeter intrusion detection system comprises: two detection devices which are arranged independently, wherein each detection device comprises a camera, a light source and a back board for fixing a light source; the two cameras are arranged in a direct facing manner and each of the two cameras is used for imaging the light source in the opposite other detection device; at least one detection device is further internally provided with an image analysis and data processing module; the two cameras are connected with the image analysis and data processing module respectively. According to the perimeter intrusion detection system, bidirectional imaging is adopted, and the size of an intruder can be judged through an imaging height of the intruder in the two cameras under the condition that the height of the light source and a distance between the two cameras are known, so that false alarm caused by the fact that tree leaves or small animals shield light beams of infrared emission is effectively eliminated. The perimeter intrusion detection system has the characteristics of high alarming accuracy, high environment adaptability, easiness of installation, convenience for utilization, low cost, integration of video functions and the like.

Description

technical field [0001] The invention relates to the technical field of perimeter security protection, in particular to a perimeter intrusion detection system and method, which are mainly used for perimeter protection around buildings, and also for protection of doors, windows, and aisles inside buildings. Background technique [0002] Perimeter security refers to important areas, such as national defense borders, military bases, key government departments, oil depots and coal fields, nuclear power plants, solar power plants, power plant substations, banks, prisons, museums, airports, ports, villa communities, data centers, water treatment Factories, chemical plants, schools and other major infrastructures, in order to prevent illegal intrusion and sabotage activities, form security precautions along the perimeter of the site to block intruders outside the perimeter. [0003] Traditional safety precautions are to set some physical protection (such as iron fences, walls, wire ...
