The old desire of human beings in protecting their life and property from the harms of earthquakes led to development of scientific ambitions in realms of seismography and seismic detecting.
Out of anti-earthquake endeavors, the seismic sensors found their way in protecting sensitive areas like banks, military bases, borderlines, and pipelines from illegal intrusions or diggings.
The growing popularity of the new technology in safeguarding civilian and military hotspots drove an Iranian science-based company to design and manufacture the first Iranian version of the device, dubbed as 'Hafez' which in Farsi means protector or guardian.
The system which is comprised of seismic sensor, signal convertor and power source, has benefits like being passive, not changing site aesthetics, and having a covert presence as it does not need direct sighting of the area.
The system also allows authorized activity in the vicinity of the protected area defining personal signals for each user.
