Effectively suppresses microphones with ultrasound at the distance of several meters The device is equipped with 5 ultrasonic transducers. They generate interference signal using unique algorithm, specially designed for maximum impact on any eavesdropping devices. Interference signal affects the recording paths of electronic devices causing sound distortion. As a result, the record contains only unintelligible noise thus it is impossible to understand what is the conversation about. The device is capable of suppressing recording devices at the distance of several meters. That is one of the highest results for equivalents. |

Perfect solution for concealed use Ultrasound interference suppresses any recording, but it remains unheard for people and it does not interrupt the conversation. Operating device does not reveal itself that allows you to use inconspicuously. Compact sizes of the device and quick start allow using it in any circumstances. |

The device has a jack for connecting an external acoustic speaker for transmitting speech-like interference through it. Therefore, eavesdropping devices record only unintelligible mumbling and it is physically impossible to restore the conversation. |
The interference signal is spread not only in front of the transducers, but also sidewise thus suppressing dictaphones which the device is not directed to. |
The device operates autonomously for several hours thanks to the battery with 2500 mAh capacity. |
