IRIS CONTROL Fixed Iris
In indoor environments where light levels may be constant the iris opening cannot be adjusted and is fixed at a certain f-number
f-stop that cannot be varied.
Manual iris
iris can be adjusted by turning a ring on the lens to open or close the iris.
This is not convenient in environments with changing light conditions
Auto Iris It's motor-driven, automatically adjustable iris opening that responds to
changes in light levels
The ability to adjust automatically to lighting conditions.

Iris-based biometric devices analyze the features found in the colored ring of tissue that
surrounds the pupil.
recognition solutions analyze-facial characteristics with geometric point algorithms. It
requires a digital camera to develop a facial image of the user for authentication andcompares the image to a database
