What is an auto iris and how does it work?

Like the digital camera, security cameras use a cmos (Complementary metal–oxide–semiconductor) to capture and translate the image the camera sees to data which is translated back into am image that can be viewed on a monitor . An auto iris like the iris of your eye adjusts the light level to maintain a reasonable amount of brightness. The brighter the light the smaller the iris. There are two types of irises – auto (automatic) and manual. 

Manual irises are set to a single level of light while automatic use sensors to adjust exposure. 

Yes, even in technology the iris serves the same purpose and functions much the same as the human eye's iris.
