A video-based surveillance solution for protecting the air-intakes of buildings from chem-bio attacks

We propose a layered security concept for the protection of buildings' air-intakes from chemical and biological attacks. The concept is focused on prevention, early warning, and effective evacuation. One of the pillars of our concept is the inclusion of a video-based surveillance subsystem that improves the early warning capability of the protection system. Our video-based surveillance subsystem features a motion detection and tracking module based on DETER - an algorithm that we described previously. We have tested our video surveillance system on various possible attack scenarios with perfect detection results. The current weak point of our solution is that it cannot differentiate between benign and malicious human activities. We are working on incorporating a human activity recognition module, which will endow the video surveillance subsystem with threat assessment capabilities.
