INTRODUCTIONSurveillance is one of the promising applications to which smart Distributed smart cameras have received increased focus in the camera motes forming a vision-enabled network can add research community over the past several months. The notion of increasing levels of intelligence. We see a high degree of in-node cameras combined with embedded computation power and processing in combination with distributed reasoning algorithms interconnected through radio links opens up a new realm of as the key enablers for such intelligent surveillance systems. To intelligent vision-enabled applications. Real-time image put these systems into practice still requires a considerable processing and distributed reasoning made possible by smart amount of research ranging from mote architectures, pixelcameras can not only enhance existing applications but also processing algorithms, up to distributed reasoning engines. This motivate new applications. Potential application areas range from paper introduces MeshEye, an energy-efficient smart camera home monitoring, elderly care, and smart environments to mote architecture that has been designed with intelligent security and surveillance in public or corporate buildings. Critical surveillance as the target application in mind. Special attention is issues influencing the success of smart camera deployments for given to MeshEye's unique vision system: a low-resolution stereo such applications include reliable and robust operation with as vision system continuously determines position, range, and size of little maintenance as possible. moving objects entering its field of view.
