There is provided a method of detecting and synchronizing audio/video signals. At least one audio signal is detected by means of at least one microphone unit. Timestamps are generated and stored together with the detected audio signal in the microphone unit. An optical synchronization signal is output by the microphone unit, wherein the optical synchronization signal contains optical timestamps which are respectively associated with one of the generated timestamps. At least one video signal is detected by means of at least one camera unit. The video signal at least partially has the optical synchronization signal output by the microphone unit. The optical timestamps contained in the optical synchronization signal are extracted. The video signal and the audio signal are synchronized on the basis of the timestamps in the audio signal and the optical timestamps extracted from the detected optical synchronization signal.
