Northrop Grumman [NOC] has introduced a new security management solution called Airtight that uses data from existing airport sensors and infrastructure to create a common operating picture that can be shared with emergency services and first responders. The sensor fusion capabilities of the system include integrating traditional motion sensors, cameras and access control systems as well as the installed base of Northrop Grumman technologies such as surveillance radar and surface movement guidance and control systems. The company says Airtight is scalable and offers a flexible growth path for upgrades and the introduction of new technologies.
