Free Compound Eyes (フリーコンパウンドアイズ Free Compound Eyes?) or the FCE was an internet service that was provided by the Blueshake Media Network. It was used as an easy way for users to setup cameras, and remotely access them through the internet. The FCE becomes a key component in the success of the invasion of Hawaii, as Olay Blueshake used it to gain valuable information against the defending American forces. In fact, the entire volume the 3rd Shinyaku Toaru Majutsu no Index shows the pervasiveness of the technology via cameras that are accessed through it showing all the scenes that occur.
