A case study on smart surveillance application system using WSN and IP webcam

摘要

Surveillance is becoming a need in any public or private area to cope up with increasing number of threats starting from burglary, robbery to terrorist activities. The traditional methods for monitoring are commonly confined in the use of CCTV cameras or wireless sensor network (WSN). These two techniques serve the purpose in different ways. CCTV cameras help in visual monitoring of target area whereas WSN helps in acquiring physical information from the environment, like change in thermal, chemical, magnetic conditions. In this paper we incorporate advantages of both technologies to build up a smart surveillance system. We have proposed a centralized computer based application that identifies movement of human beings in target area and keep the visual evidence of the movement with the help of the camera. This is an event based system, thus, substitutes the need for continuous monitoring of the area. A prototype application is deployed in university laboratory room to evaluate some preliminary functionalities of the application.
