With terrorist threats continuing to be a top concern at critical infrastructure sites, a complete detection, management, and control system is imperative for providing the confidence that the site has put all possible measures in place to prevent unthinkable disasters from occurring. When used together, powerful technologies provide complementary services from image detection through to control room decision making and can be thought of as stepping blocks in creating a highly-effective security system. By integrating the highest standard technologies at each step, the complete system is the most powerful addition to security systems: Thermal imaging is unsurpassed at detecting intruders in the dark of night and in challenging weather conditions at the sensor imaging level; Automated software detection creates an initial alert; Immersive 3D visual assessment is used for situational awareness and to manage the reaction process; Wide area command and control capabilities allow control from a remote location.
