Purpose
ULTRAVOX-TH24/110 belongs to the class of stationary devices for protecting negotiations from recording by voice recorders, smartphones and hidden microphones.
The distinctive features of the model are increased emission power, which provides effective suppression of recording devices in an extended zone. The device supports control by both wired and wireless remote controls, as well as the possibility of jointly using several devices to build a comprehensive protection system.
The camouflaged design mimicking standard interior elements and a large number of mounting options allow ULTRAVOX-TH24/110 to be integrated into meeting rooms of almost any type.
The device effectively counteracts unauthorized recording using:
- mobile, stationary and radio-frequency recording devices
- professional audio recording equipment
- hidden and external microphones
- mobile phones
Operating Principle
Ultrasonic Interference Generation
The device generates a complex signal in the ultrasonic range that is not perceived by the human ear.
24 ultrasonic emitters located on one side generate noise interference.
Effect on Microphones
The interference distorts the signal reaching the microphones, making voice recording unintelligible or completely impossible.
The interference acts directly on the microphone membrane, creating a “speech chorus” effect that renders the recording unusable.
Limitations
Ultrasound does not pass through solid obstacles (walls, furniture, partitions), so for effective protection the device should be placed within the protected area.
