The PNG-2000 is designed as a portable acoustic noise-generating unit that
can be used in a variety of ways. The noise generating circuitry has been optimized
for voiceband noise masking against listening devices and is designed to reduce
the effectiveness of eavesdropping devices such as microphones and tape recorders.
When multiple units are used in concert, a complete environment masking system
can be easily installed in any environment. The PNG-200 can be mounted to smooth
surfaces using suctions cups or simply placed in an area that potential eavesdropping
devices may be present.
Optimized voiceband noise masking for acoustic interference against listening
devices. (Acoustic noise is tailored to voice frequencies). Mounts easily
to windows using suction cup (included) to defeat the high tech laser threats.
Mounts easily to walls for protection against listening devices that rely on
acoustic leakage (ie. contact mics, spike mics, human ear). Portable: Can be
carried easily in coat pocket. Multiple units fit easily in a briefcase. Stylish
anodized aluminum construction designed for ruggedness and portability.
