This paper describes a system for the mining of surveillance video. Our main contributions are: providing a high level query language for submitting queries about spatial and temporal relations of background regions and moving entities, and about human activities; providing a compiler to map high level queries into a set of novel Petri net filters that utilize computer vision algorithms to answer components of the queries; and providing a powerful graphical interface where users have the ability to formulate the query visually.
