Actual task in development of seismic systems is recognition of objects in difficult conditions. One of options of algorithm of recognition of the person, group of people and equipment on their seismic signals is offered. As a classification sign the factor of filling of a temporary window is chosen as a useful signal. The analysis of a sign showed that for the person and group of people sharp reduction of values of a sign with object approach to a beam is characteristic. In the presence of an equipment signal, the sign practically doesn\'t change. Check of algorithm was carried out on representative volume of records of the signals which have been written down in difficult orography of the country and various climatic conditions. As a result, it is established that the expected probability of recognition can make not less than 0,9.
