Traditional centralized approaches have several drawbacks due to limited communication bandwidth computational requirements and thus limited spatial camera resolution and frame rate. In this article we present network-enabled smart cameras for probabilistic tracking. They are capable of tracking objects adaptively in real time and offer a very bandwidthconservative approach as the whole computation is performed embedded in each smart camera and only the tracking results are transmitted which are on a higher level of abstraction. Based on this we present a distributed surveillance system. The smart cameras tracking results are embedded in an integrated 3D environment as live textures and can be viewed from arbitrary perspectives. Also a georeferenced live visualization embedded in Google Earth is presented. Copyright 2007 Sven Fleck et al.

INTRODUCTION In typical computer vision systems today cameras are seen only as simple sensors. The processing is performed after transmitting the complete raw sensor stream via a costly and often distance-limited connection to a centralized .
