Thirty cameras are spread throughout the level, mounted on walls 2-3 meters above floor level. All can be accessed in the process of unlocking the major parts of the level during the mission Science and Violence, although one is hidden on a lower level (part of the challenge Leap of Faith II). All of the cameras are very easy to kill; even explosive damage nearby can knock them down. If approached, their normally green activity lights will turn red and they will track the vault hunter; this does not invalidate the challenge.
