proper light levels on the face-plate of the camera pickup device.
Video Type Auto

voltage and a video signal from the camera to adjust the iris.
DC Type Auto
Iris Lens An auto iris lens without an internal circuit to control
the iris. All iris control voltages come from a circuit located within
the camera.
Manual Iris

stop) in a fixed position. Generally used for fixed lighting applications.
Angle of View

lengths give a wide angle of view and large focal lengths give a narrow
field of view.

the greater is the amount of light passing through the lens.
