The StarWitness Array allows users to electronically steer 16 or more microphones so the audio surveillance can be directed at a target of interest - without physically moving the array. This capability is invaluable in situations where targets are in motion, such as outdoors or in large rooms, or in crowded areas such as a restaurant. It's also more subtle than larger "shotgun" microphones, making it the tool of choice for serious covert operations. From Signalscape, StarWitness Array can be guided two ways toward a target: from a video camera inetgrated with the array or audio waterfall steering.
