Detecting Hidden Items in the Surrounding Environment
Contraband cell-phone use in correctional facilities can allow convicted offenders to continue their illegal activities from
behind bars. Detection technology that can help corrections officials locate contraband cell phones being used in prisons
could help prevent future crimes.
To further these capabilities, NIJ is funding Intelligent Automation, Inc., to develop an electronic detection system that
can detect and locate wireless communication devices inside or outside of buildings. NIJ-funded engineers are developing a
prototype to be tested and evaluated in a correctional facility. This technology pinpoints location by analyzing the arrival
of radio waves from a cell phone at different locations.
Detecting Substances Present in the Surrounding Environment
Law enforcement gathers investigative information by detecting chemical substances at crime scenes. Detection technology can
alert authorities to the possible presence of illegal drugs or chemicals used in their manufacture — for instance, in home-based
methamphetamine labs. This technology also may detect chemicals that could be used to make homemade bombs.
