Tape Recorder Blocker


Availability: In stock

This counter surveillance device is specifically designed to block digital or tape recorders, and all microphones associated with transmitters/listening devices, by emitting a sub-audible tone which cannot be detected by the human ear but will drown out any recordings when played back.

The unit's suppression range for digital records is 0.5-2metres and 3-8metres for tape recorders on a suppression beamwidth of 100 degrees vertical and 80 degrees horizontal. This counter-surveillance device is supplied with a remote control that can activate and de-activate the unit from within a 7 metre range.

The unit has a built-in clock and can be used as a desktop item by simply placing a telephone on top of it. It also comes with a smart document holder so that it can be carried around to provide counter-surveillance protection wherever you may be. The in-built re-chargeable batteries provide 2.5 hours of uninterrupted use.


Not to be used in hospitals or near medical equipment, including pacemakers or hearing aids.
Not to be used in aircraft.
Not to be used in potentially explosive atmospheres, including petrol stations, fuel depots, chemical plants or any area where blasting operations are in progress.
This unit can interfere with the operation of technical installations and cause fire or explosion.
