KOL 15FC is a combination of two technologies: The first one can simultaneously neutralize the microphones of up to 15 mobile phones and two tablets by generating ultrasonic sound. The second one is embedded in the box itself. This technology includes copper fibers that form a Faraday cage that neutralizes any type of radio frequency within the box.

The combination of the two technologies neutralizes any possibility of recording, broadcasting and remotely listening to the cellular devices that are placed inside the KOL15FC and makes it ideal for use inside a conference room. The system works by connecting to 220v electricity as well as an internal battery that allows it to operate for 10 hours continuously.

The system blocks the microphones of any type of phones / tablets.
