An apparatus for testing infrared cameras includes: a front plate which has holes arranged in line, and which is adapted to emit an amount of infrared light; and a back plate which is disposed in parallel to and behind the front plate as viewed from infrared cameras to be tested, and which is adapted to emit a different amount of infrared light when compared with the front plate. The back plate is disposed at lower portions of pillars. On the other hand, the front plate is made vertically movable in front of the back plate and along the pillars. By being controlled by a controller, the front plate is movable from the ground height to a level corresponding to approximately two times the height of the back plate.
