Appendix #3 - DC Auto Iris Lens Installation
Lenses for this IP product are sold separately. DC Auto Iris and CS-Mount lenses are compatible
with this product. Please note that:
• Use of an auto iris lens is recommended to achieve the best results for operating this product
effectively under a wide range of lighting conditions. 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.
• Please keep the lens clean.
• Any foreign objects and finger marks on the lens will cause inferior image quality in low light
level conditions.
