One important goal of surveillance systems is to collect information about the behavior and position of interested targets in the sensing environment. Traditional video surveillance systems usually cannot provide complete information of interested targets since they are limited by single and fixed monitoring directions. Recently, surveillance systems combining wireless sensor networks with video cameras have become more and more popular. In this demonstration 1 , we show a multi-view
