System and method for two-level protection for accessing closed and semi-closed enclosures

摘要

The system is constituted by physical and electrical barriers, with components of sensing and alarm of the first and of connection and activation of the last, all connected to the internal source constituted by set of batteries or conventional electrical system, the last one provided of batteries pack, for coverage of eventual electrical supply failures, for the length of time considered more convenient by the user. The system prevents access to closed or semi-closed enclosures, so that the detection by the sensing and alarm component of the simple approach of intrusion agent at a distance below that established activates the electrical barrier connection and activation component fed by its own sources or conventional, substitutable by the own sources in case of external supply drop, making the entire energized electric barrier practically impregnable to burglary, due to the discharge of high voltage and low amperage, as appropriate.
