configurable since the sensor library will automatically adjust the value according to the ambient light. Then you can configure 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 field. 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 field 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 field).

•The smallest number, 1, means the iris is narrowed down as much as possible (smallest amount of light received with longest depth of field).

•The largest number, 100, means the iris is open as wide as possible (largest amount of light received with shortest depth of field).

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.
