Secure and interoperable observation data and information management services using open standards shall be deployed in ZONeSEC with the aim of cost-effectively reusing them in the surveillance of many other European WideZones. These services are part of an advanced Knowledge Base (KB) and primarily focused on large-scale surveillance with high-performance detection of localized abnormal activities and alerts. Semantically enriched domain knowledge representations shall be stored in the KB for supporting high-level data fusion and reasoning with reduced uncertainties and false alerts. Surveillance professionals will securely subscribe to the scalable KB services of the ZONeSEC system of systems with customizable visualization features. Several pilots specializing in the detection of illegal unauthorized entrances to or trespassing premises; or actions to damage to or deployment of harmful devices on installations shall be fully demonstrated. These concern Water, Oil, and Transnational Gas Pipelines; Highways, and Rail tracks conveyed in six European countries.
