A '''visual sensor network''' or '''smart camera network''' is a network of spatially distributed [[smart camera]] devices capable of processing, exchanging data and fusing images of a scene from a variety of viewpoints into some form more useful than the individual images.<ref>{{cite journal |last1=Tavli |first1=Bulent |last2=Bicakci |first2=Kemal |last3=Zilan |first3=Ruken |last4=Barcelo-Ordinas |first4=Jose M. |title=A survey of visual sensor network platforms |journal=Multimedia Tools and Applications |date=1 October 2012 |volume=60 |issue=3 |pages=689–726 |doi=10.1007/s11042-011-0840-z |url=https://link.springer.com/article/10.1007/s11042-011-0840-z |language=en |issn=1573-7721}}</ref><ref>{{cite journal |last1=Williams |first1=Adam |last2=Ganesan |first2=Deepak |last3=Hanson |first3=Allen |title=Aging in place |journal=Proceedings of the 15th international conference on Multimedia - MULTIMEDIA '07 |date=2007 |doi=10.1145/1291233.1291435 |url=https://dl.acm.org/doi/abs/10.1145/1291233.1291435 |publisher=ACM Press}}</ref> A visual sensor network may be a type of [[wireless sensor network]], and much of the theory and application of the latter applies to the former. The network generally consists of the cameras themselves, which have some local [[image processing]], communication and storage capabilities, and possibly one or more central computers, where image data from multiple cameras is further processed and [[sensor fusion|fused]] (this processing may, however, simply take place in a distributed fashion across the cameras and their local controllers). Visual sensor networks also provide some high-level services to the user so that the large amount of data can be distilled into information of interest using specific queries.<ref name="obraczka2002">{{cite book|first=K.|last=Obraczka|author2=Manduchi, R. |author3=Garcia-Luna-Aveces, J.
