The present invention refers to an audio module for a video surveillance system, a video surveillance system and a method for keeping a plurality of locations under surveillance. Video surveillance systems are widely used to monitor critical locations of public or private buildings or institutes like private homes, museums, prisons, factories, hazardous areas and so on from one or more central surveillance rooms. Commonly, the surveillance rooms are equipped with a plurality of monitors each displaying one of the critical locations or a mosaic display, which is divided in a plurality of cameos, whereby each cameo displays one of the critical locations. Additionally audio signals corresponding to the images displayed on the single monitors or cameos can be played. An audio module (1) for a video surveillance system (8) with a display screen (10) which is organized in a plurality of cameos (14, 15) is proposed, the audio module (1) comprising input channels (2) for audio-in-signals individually referring to the cameos (14, 15), an allocation table allocating the audio-in-signals to the cameos (14, 15) and output channels (3) for audio-out-signals whereby audio positioning means which are realized to generate the audio-out-signals as stereophonic and/or surround sound signals on the basis of the audio-in-signals and the allocation table.
