Simulation of a video surveillance network using remote intelligent security cameras

Abstract

The high continuous bit-rates carried by digital fiber-based video surveillance networks have prompted demands for intelligent sensor devices to reduce bandwidth requirements. These devices detect and report only significant events, thus optimizing the use of recording and transmission hardware. The Remote Intelligent Security Camera (R.I.S.C.) concept devolves local autonomy to geographically distant cameras, enabling them to switch between tasks in response to external events and produce output streams of varying bandwidth and priority. This paper presents an investigation of the behavior of such a network in a simulation environment, with a view to designing suitable algorithms and network topologies to achieve maximum quality of service and efficient bandwidth utilization.
