The Tactical Automated Security System (TASS) is a U.S. Air Force intrusion detection and surveillance system used for security monitoring around fixed site airbases, semi-permanent Forward Operating Bases (FOBs), and other mobile tactical deployments. The system consists of thermal imagers, sensors, communications, power and annunciation components. The system provides for wide-area and perimeter intrusion detection, assessment, and surveillance via both hardwire and UHF/VHF communications.
