Active infrared sensor for monitoring protected areas

摘要

The analysis of typical ways to build tools of control of the security perimeter and intrusion into the protected area. The method of compensation of the effect of ambient light, the block diagram and measuring information processing algorithm of active infrared sensor of reflecting type, allowing to use it to register movement, is reviewed. The results of experimental studies of the device to control the intrusion into the protected area on the basis of active infrared sensor of reflecting type are considered.
