Integration of surveillance data with other sensor data

Integration of video surveillance with the recording of signals from other sensors into a single system will improve the effectiveness of safeguarding complex nuclear installations and reduce the effort required for data review. Sensors that could be combined with optical surveillance are radiation monitoring devices, electronic seals, and environmental and event sensors. The paper deals with some aspects of system integration that are related to the acquisition of data from different sensor types, their processing and the control between sensors. Several examples of technical solutions, already implemented or in development, are presented. (author). 4 refs, 3 figs
