Auto Iris Lenses are perfect for locations, where light is constantly changing, such as outside parking lot, and building entrances. Auto Iris Lenses are powered through cameras power supply. The iris for these lenses automatically opens and closes according to the changes of the light conditions. If the light level is low, the lens iris opens up to allow enough light for optimum picture quality, and when the light level is high, it closes the iris so that incoming light does not overwhelm the camera and blur out the picture.
Hope this helps.
