Room monitor for counting and treasury rooms e.g. in bank - combines TV monitoring with acoustic monitoring using microphones in room and sound records associated with them

摘要

The room surveying system includes at least one microphone (4) and a sound recorder (6). The latter is connected to the TV surveying system (5) in an emergency and records ensuing events via at least one microphone (4). The emergency signal generator, the microphone and the recorder are connected by cables or by radio connection. The microphone is built into the room, e.g., in the floor, a wall or the furniture. If several microphones are used, different channels of a multi-channel recorder are allocated to each. The sound recorder may be installed in a special locked room (3). The acoustic surveillance can be carried out without the TV surveillance. ADVANTAGE - Improves security and is further possibility in effectively combating crime.
