Abstract: A method and system with means for preventing unauthorized monitoring of a local conference room (1) in which a local conferencing system (2) is located comprising generation of a deterministic sound signal (300), and loading the deterministic sound signal on a first loudspeaker (5) connected to, or integrated in the conferencing system (2), detecting the deterministic signal (600) by analyzing a microphone signal picked up by a microphone (4) connected to, or integrated in the conferencing system (2), and transferring the conference system (2) into a security mode (1100), if the deterministic signal is not detected.
