    • A method of determining an intrusion into a monitored area comprises the evaluation of images of specific optical pattern (40) arranged behind said monitored area. The system comprises at least two imaging devices (20) spaced from the plane of said monitored area; a predetermined optical pattern (40) positioned outside and behind said monitored area; at least two mirror (30) directing the images of said optical patterns (40) to said imaging devices (20); a processor receiving and processing image data provided by said at least two imaging devices (20) to detect any optical change and to determine the position of an intrusion causing optical change within said predetermined area; an output signal generator for generating an output signal depending on the relative position of said intrusion.
    • 确定入侵到被监视区域的方法包括评估布置在所述被监视区域之后的特定光学图案(40)的图像。 该系统包括与所述被监测区域的平面间隔开的至少两个成像装置(20); 位于所述监视区域的外部和后面的预定光学图案(40); 将所述光学图案(40)的图像引导到所述成像装置(20)的至少两个反射镜(30); 接收和处理由所述至少两个成像装置(20)提供的图像数据以检测任何光学变化并确定在所述预定区域内造成光学变化的入侵位置的处理器; 输出信号发生器,用于根据所述入侵的相对位置产生输出信号。
