Ultrasonic Voice Recorder Suppressor
«Ultrasonic-Sektor-24-GSM»
255º suppression angle, mobile communication jamming

Area of use

«Ultrasonic-Sektor-24-GSM» suppressor is intended for use in office and meeting rooms and is installed under the negotiation table. With proper installation, you will be able to make recording, while recording by interlocutors will be impossible. The ultrasonic effect on microphones and voice recorders, as well as the operation of the built-in communication suppressor, will protect the room as much as possible from information leakage.

Features Operation invisible to others. The suppressor is installed under the table and operates silently, so your interlocutors will not be aware of its use.   You can record a conversation, but the rest can not! Ultrasonic emitters are arranged in such a way that you are the only one able to record.   Ultrasonic Sound Suppression. The suppressor is equipped with 24 ultrasonic emitters impacting the microphone membranes of any recording devices, thereby making sound recording impossible.   Data transfer block. The built-in communication suppressor blocks communication in the GSM, Wi-Fi, 3G, 4G, LTE, GPS bands, making it impossible to transmit information.   The remote control allows for the remote control of suppressor’s operation, without attracting the unwanted attention.   Ability to operate using battery (optional). Allows you to use the suppressor autonomously for up to 2 hours, which will be useful in the absence of a 220V network in the place of use of the device.   Protection against laser microphones (optional). At your request, this device can be equipped with special vibro-acoustic emitters that interfere with the remote reading of information off the window glass of the meeting room and provide reliable protection from laser microphones.
