Seismic detection tools are widely used in the system-max security from the beginning of the 70-ies of the XX century. Despite the efforts of designers, immunity seismic systems remains low. The difficult task is detection and accurate differentiation of people and vehicles on the background of biological interference. In article on the basis of patent information the analysis of the most important technical solutions in the field of seismic detection systems. On the basis of the analysis of technical decisions of the given classification of methods of processing of signals and systematized space of features to work seismic detectors and classifiers. The article reflects the current state of practice of seismic detection systems.
