TSS

The combination of growing threats and increasing security awareness is driving the design of large and larger perimeter protection systems at nuclear facilities worldwide. This paper reports on the Tactical Security System (TSS) which is a modular, solid-state video system that adds Pre-Alarm Image Recall (PAIR) assessment capabilities to existing fixed-site surveillance systems. PAIR allows guard forces to view video images taken prior to perimeter sensor alarms. The system can be configured to show from 8 to 64 such images for each alarm and can display multiple cameras and multiple zones simultaneous. The TSS hardware architecture can be configured to include capabilities for digital image storage, image transmission, image printing, video loss detection, video motion detection and security force training. The incorporation of all of these video-based functions into one system give guard focuses and integrated workstation for video detection, assessment, documentation and communication. It reduces the number of responses to nuisance alarms and increases confidence in guard force decisions
