In this paper, a block diagram of a microelectro-optical intelligent passive infrared motion detector is proposed. On the basis of the proposed structural scheme and analytically conducted synthetic processing of information from primary sources [5-17], boundary conditions for the directivity diagram of such a detector are determined. The analytical information collected in this article will be necessary for further modeling in computer-aided design with a view to new developments and improvements to existing motion detectors

The principle of work of modern passive infrared motion detectors of the known world manufacturers is considered; their peculiarities and fields of use are indicated. Both the typical structural and schematic diagrams are given. The basic parameters of modern passive infrared motion detectors and their boundary conditions have been determined based on the principle of operation of the detector and the synthetic processing of information from primary sources. The boundary conditions for the number of rays of the near middle and far zones of the pattern of motion detectors are given.
