ULTRAS this is Advanced Recorder Suppression Ultrasound System in form factor of a built-in speaker
An increased power ultrasonic suppressor located in the body of the ceiling speaker, which is built into the suspended ceiling directly above the negotiating table. Designed to prevent unauthorized audio recordings to any recorded devices in offices or other rooms
ULTRAS is a powerful and effective device for suppressing microphones in voice recorders, mobile phones and other means of audio recording by emitting complex structured interference in the ultrasonic range, inaudible to the human ear, but acting directly on the microphone membrane with its sound pressure.
Advantages and features
Structurally, the ULTRAS suppressor with 24 ultrasonic emitters is made in the form of a cylindrical module with a thickness of only 40 mm; it is easily mounted in the cases of various mortise ceiling speakers used in emergency warning systems and music broadcasting.
For even greater power of ultrasonic interference generated by the ULTRAS suppressor, it is possible to install a module with 48 ultrasonic emitters into the ceiling speaker housing.
Due to the ceiling arrangement of the emitters and the resulting effect of repeated reflections of ultrasonic interference from interior objects, the area and effectiveness of suppressing recorder's microphones and other audio recording means introduced into the room increase
The microprocessor control system, automatic continuous self-diagnosis of the operation of each ultrasonic channel maintain a constant highest level of ultrasonic interference power throughout the entire operating time, ensuring high reliability of the product and ease of use.
The ULTRAS suppressor turns on automatically when power is supplied (+12 V) or can be remotely controlled using a radio keychain.
