What is Signal Defense and Why Do I Need It?

Signals Defenses® Technology (SD) is a patented, optically clear, Radio Frequency (RF), Infrared (IR) and Ultraviolet (UV) blocking window film, glass or polycarbonate (PC).  Deploying SD Technology to fenestrations will provide privacy/eavesdropping protection, additional security for wireless networks/devices, and RF sheltering for equipment and humans with very HIGH solar energy/UV blocking.

The SD2500 Film provides the HIGHEST levels of RF and IR attenuation, meeting and exceeings the requirements of various US Government organizations’ specifications for optically clear RF/IR/UV attenuating film/optical coatings, especially with respect to IR. It is listed by DoD as an RF/IR Attenuation film tested to be “beneficial” as Alternative Shielding including TEMPEST Countermeasures.
