visual sensor network


Also found in: Dictionary, Wikipedia.

visual sensor network

A network of wired or wireless video cameras distributed throughout a building or outdoor area that provides a continuous surveillance of the environment. A visual sensor network (VSN) presents a coherent picture of the environment to the user rather than just a collection of individual video clips. Preprocessing often takes place within the "smart" cameras before sending the data to a central computer that performs additional processing. See computer vision.

Following the development of these inexpensive, powerful, and easily-deployable visual sensors, wireless visual sensor networks (WVSN) consisting of wireless, battery-powered, and field-of-view (FoV) overlapping and stationary visual sensors have been widely employed for surveillance in public places [1,2].
