Factsphere Sensor

A Factsphere Sensor is essentially an advanced camera that relays live 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. A similar scaled down system can be seen on some special infantry (like Private Kururugi) as a HUD like system used to relay video feeds, enhance low light visibility, and identify objectives. This infantry system is helmet based and is located on the brow, using two periscope like eyepieces that cover the eyes to allow viewing.
