Free Compound Eyes

Free Compound Eyes (フリーコンパウンドアイズ) 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.

Use and Operation
The FCE is used to easily setup cameras, connect to the internet, and construct a secure camera network without purchasing an expensive plan with a security company. This applies to any Wi-Fi ready electronic equipment that has camera's already pre-installed. The service is hosted by the major search engines and is provided by the three major internet service providers in America.

Background
The technology was brought upon after Olay Blueshake bought three of the United State's three major internet service providers, as well as the major internet search engines. However, after it was revealed by white hat Hackers that anyone could see the images produced by a third party's camera by only entering its registration number, and that the major search engines could see through the cameras all over the country.

This would later reveal Olay Blueshake's personal life, regarding her abuse of her husband and daughter. More importantly, the Fair Trade Committee advised them to correct the issue and the service ended. Of course, the software still remained within the servers, and the underlying fear that the level of control over the cameras it gives may become heightened is not unfounded, as it came to frution. With the FCE still existent, all camears that are connected to the networks of the the internet service providers, Olay could ontrol all cameras that are connected to their network. Olay would later used the advancement of the FCE as a way to search for her daughter, the sole heir to her empire.

The FCE is used extensively during the arc, with cameras recording every movement Kamijou Touma and company make. The presence of cameras being used to monitor them comes up briefly durin their first encounter with Saronia A. Irivika, believing that she is monitoring their actions.

It is not until deep into the invasion that the true nature of the invasion is revealed that the FCE is probably used by Olay. Although at that point, Touma and everyone else were too preoccupied with the invasion and rescuing Lindy Blueshake than to deal with the FCE. This would later complicate things, as footage of Touma, Accelerator, Hamazura Shiage, Misaka Mikoto, Misaka Worst, and Kuroyoru Umidori, would be found on the laps of the 27 Cooperative Institutions via Leivinia Birdway's manipulation in order to force GREMLIN to move in a favorable position for her, ending their cooperation with Academy City, after worries that the "agents" (Touma and company) of Academy City were deliberately trying to involve in the affairs of other nations. This strained Touma's relationship with Leivinia, forcing him to go out on his own.
