The Vicon Net Video Intelligence Module from Vicon Industries Inc. of Hauppauge, New York, is a video intelligence system used for detection of unusual events or behaviors. Users can monitor and analyze events, set event-detection criteria, and control parameters by applying rule-based algorithms to captured video. They can detect motion, absence of motion, theft, and behavior changes, among other events. The system is designed to compensate for light changes, shadows, reflections, car headlights, and other outdoor environmental events. It offers low false alarm rates and nuisance alarm rates without compromising on high probability of detection levels. The system uses video analytics software from Agent Vi of New York City.
