Defentect Group, Inc. [DFTC] says the first of several installations of its GammaTect radiation detection sensors have been completed at National Naval Medical Center in Maryland. The sensors were installed with Defentect’s DM3 sensor agnostic messaging platform that allows customers to add various sensors to their security systems, as well as controlling video surveillance cameras. The sensor system was installed by Exigent Security Products and marks Defentect’s entry into the government facilities market. Several other locations across the medical center campus are expected to be equipped with the solution in the coming months.
