Validate Privacy Constraints in Surveillance Systems

The paper introduces a video surveillance and event detection framework and application for semi-supervised surveillance use. The system development follows the guidelines of national strategy for surveillance systems. The aim is to generalize the interoperability, compatibility and legality in camera surveillance systems in Hungary. The system’s intended use is in automatic mode on camera feeds that are not actively watched by surveillance personnel, and should raise alarms when unusual events occur. We present the current detector filters, and the extendable modular interface. Filters include local and global unusual motion detectors, left/stolen object detector, motion detector, tampering/failure detector, etc. It has been tested in real life situation for police street surveillance.
