Factsphere Sensor

A Factsphere Sensor is essentially an advanced camera that relays thermographic images and data to the pilot. They are usually protected under a retractable layer of armor. When retracted it allows for greater system sensitivity. Earlier generation Knightmare frames typically place a single factsphere sensor on the head of the unit, while later models place one on each shoulder. Lelouch's Shinkirō, has a single factsphere sensor mounted on its forehead without retractable armor, due to its absolute defense system.
