Automatic Threat Assessment: Tracking System Tells Friend from Foe

August 1, 2013 - By

Ongoing threats from terrorist activities at critical facilities require early detection before the threats can reach their target and complete their mission. This has produced the need for advanced security systems to effectively detect terrorist activity, while reducing alarms caused by normal friendly activity. Automatic Threat Assessment, also referred to as Identify Friend or Foe (IFF), is the ability to automatically acknowledge alarms created by friendly assets. It can be achieved with a security system that uses GPS and geospatial data to go beyond the typical intrusion-sensor-only configuration. read more
