Sentinel-a technology for practical automatic monitoring of busy and complex scenes

The author reviews the problems which surveillance missions present to automation and includes examples that cause conventional systems to fail. Sentinel is an automated scene monitoring system specifically designed to overcome these problems. The technological approach used in the Sentinel system is presented, the advantages this gives and how they may best be exploited are discussed. A practical example is shown and the way that Sentinel is deployed, including the necessary setting up, is illustrated. Surveillance performance results are discussed
