Abstract: The present invention provides systems, methods, and computer program products for use in monitoring, and/or surveillance applications. Generally, systems provided include embedded devices with integrated sensors, manager software capable of supporting the particular sensors and embedded devices used, and a hierarchical database structure for storage and retrieval of continuous or event-based data. Preferred embedded devices advantageously include integrated audio, video, and wireless technology to provide an array of sensory detection, analysis, and interactive controls. Preferred database structures advantageously incorporate a secure archiving scheme for retrieval and/or analysis in multiple formats.
