SEL-151 SHKATULKA-LUX acoustic noise generator for cellular phones
DESCRIPTION
SHKATULKA-LUX device is designed for protection of voice information that can be eavesdropped by a cell phone, remotely activated in secret. The device configuration makes it possible to place several cell phones in it.
The built-in RF analyzer detects when phone transmitter turns on and and automatically activates noise generator of the device. The noise level reliably provides supression of phone's microphone.
Distinctive features:
• The detector of the device recognizes not only speech mobile traffic, but also mobile data traffic.
• The acoustic noise generator produces 2 types of signals: "acoustic white noise" and pseudorandom signal "speech chorus".
• The device has an internal operational time counter with LCD display and indicators of operation modes and battery status.
• The device is made out of natural stone.
