congurable since the sensor library will automatically adjust the value according to the ambient

light. Then you can congure iris mode as “indoor” or “outdoor” to reach the best image quality.

■ Iris mode (When the Auto Exposure mode is selected):

Select Indoor or Outdoor iris mode to

adapt to the installation� The preset iris aperture setting will apply�

■ Iris sensitivity (When the Auto Exposure mode is selected): This option tunes how quickly the

P-iris adapts to changes in environments for controlling image quality and depth of eld. 10 is the

most sensitive, and 1 the least�

■

Iris Adjustment (this option is available when the Manual mode is selected):

The camera comes with a P-iris lens, which controls the iris opening with extreme precision by

its built-in stepping motor� Via software controls, the lens maintains the iris opening at an optimal

level at all times, resulting in superior sharpness and depth of eld as well as image quality.

You can manually tune the value of iris opening (aperture size), which can range from 1 to 100

(long depth of eld).

• The smallest number, 1, means the iris is narrowed down as much as possible (smallest

amount of light received with longest depth of eld)�

• The largest number, 100, means the iris is open as wide as possible (largest amount of

light received with shortest depth of eld).

Once set, the iris will stay at current position as long as the lighting condition allows� When

external lighting conditions exceed an acceptable range, the P-iris mechanism adjusts itself�
