Blocking Audio Surveillance.
Signal defence security film has applications beyond simply blocking Wi-Fi signals which are transmitted in the same unregulated 2.4-gigahertz band that is used by many cordless handsets.
Since new laser microphone technology can now easily pick up voice data through a window, by shielding against signals across a wide swath of the electromagnetic spectrum, including the near-infrared, signal defence security film can block eavesdropping technology that depends on transmissions in the near-infrared, or terahertz range.
Keeping Signals In or Outs
Signal defence security film can keep signals in (preventing attempts to spy on electronic communications) or out, minimizing radio interference and even the fabled electronics-destroying electromagnetic pulse (EMP) generated by a nuclear blast.
