Raw Events

Composite Events

• Elaborates video streams coming from distributed cameras and forward them to the monitoring station

• Publishes raw events like motion_detection and object_recognition

• Receives configuration and PTZ commands

• Elaborates and publishes data retrieved from the corresponding WSN

• Publishes periodical report and alerts for anomalous measurement

• Receives configuration command

• Receives video from CCTV server

• Allows “first-level operator” to visualize all the events and alerts exchanged through the UMVS middleware, generate new alerts, and send configuration commands to the WSN managers and the CCTV server

• Allows “second-level operators” to receive a subset of the events/alerts generated by the system and to generate a subset of alerts addressed to other operators

• Subscribes to a specific set of composite events

• Changes the public/ commercial displays to inform users of exceptional events (e.g. evacuation order) by switching to a pre-programmed alternative content that leads passengers prominently to the emergency exits.

• Subscribes to a specific set of composite events

• Informs passengers provided with legacy personal mobile devices of general interest events (e.g. evacuation order) by sending a broadcast message (e.g. RSS feed)

is an entity contributing to (insert/remove) and/or consuming query/subscribe) SIB content. It operates only on the portion of the ontology graph relevant to its tasks
