Method of intruder detection and device thereof
First Claim
1. A method of intruder detection, comprising of usage of more than 1 sensor, represented by cameras that are arranged with fixed spatial orientation to form a stereo detector of 2D distributions of light intensity of a surveillance zone, that form stereo images registered by said stereo detector, transmitting the stereo images to processing blocks, for performing processing of a sequence of stereo images with different frequencies (high and low), for determining the presence of an intruder, a position of said intruder and a speed of transference of said intruder.

Abstract
Disclosed is a method of intruder'"'"'s detection, comprising of using of more than 1 sensor, represented, for example, by video cameras that are arranged with fixed spatial orientation for stereo detector formation at that 2D distributions of light intensity that form stereo images registered by stereo detector are transmitting to blocks of processing, for example, blocks of digital processing at that mentioned blocks of digital processing perform processing of sequence of stereo images with different frequencies (high and low), to determine the presence of intruder, it'"'"'s position and speed of transference.
