Аnnotation: The main goal of the study is an experimental verification of the possibilities of using seismic systems for autonomous monitoring and protection of land and sea boundaries. The use of seismic systems as an integral part of signal-guarding complexes, especially in water areas, makes high demands on the characteristics of seismic equipment. The primary task in the experimental studies was the development of appropriate domestic equipment and methodological support, which allow study in terrestrial conditions and water areas. Therefore, the primary task was to prepare for the study the relevant domestic equipment and methodological support, which should provide work in terrestrial conditions and water areas. Production of domestic broadband equipment with such characteristics, and especially bottom ones, at the time of setting the task was practically absent. Fundamentally new technical solutions made it possible to create a number of modern models of seismic modules of the type SM-5, SM-6, SM-3M. On their basis, one-component and three-component short-period and broadband prototype seismic sensors of SM-5M, SM-6, TS-5, TS-6MSH and others were used. These models were used to develop a mockup of a digital bottom seismic station for large depths. In addition, a ground station for transit zones was developed and tested based on molecular-electronic sensors, which have recently developed significantly. The article contains the materials of the development and the results of tests of mockups of digital bottom seismic station ZDSS-M for large depths and small-sized bottom module MDM for transit zones on the basis of a new generation of electrodynamic and molecular-electronic sensors. The test carried out in the lake Seliger water area. The results of the analysis of registration materials in various conditions according to the developed methods have confirmed the specified characteristics and reliable operation of the mockups and methodological support in shallow water areas. An important result of the work is organization of industrial production of TS-5 seismic modules, which solves some problems of import substitution.
