The WG 1000 Recorder Blocker has been specifically designed to prevent the effective use of recorders (digital or tape) as a means of covert surveillance by omitting a sub-audible sound that is only picked up by microphones associated with recorders, transmitters, bugs and similar.
When recordings of conversations where this has been used, are played back a tone will be heard over and above any speech.
This unit suppresses the operation of the recorders by radiating noise interference; the parameters of the noise interference are specially adapted for suppression of many types of recorders.
In addition, this unit will protect against being listened to by many types of the eavesdropping devices such as audio transmitters.
It can be used as a desktop device in the office or as a standalone device in a briefcase.
It is specially designed to disguise its actual function.
You can put any office item on top of it (such as phone set, penholder, etc.).
