【Camera Settings】
Lens (IRIS Control): Select DC or Manual for IRIS control. This function is only available for
EDN3260 Plus.
Exposure Settings (AE): This setting is used to adapt to the amount or type of light used by the
camera. The functions vary among models.
Mode:
 ALC: Selecting Automatic Light Control to allow the camera circuitry to either take bright
spots more into consideration (peak), bringing out detail in bright areas, or less into
consideration (average) bringing out detail in shadows.
 AES: Selecting Auto Electronic Shutter to enable the Slow Shutter setting below this setting.
In this mode, the camera measures the light level and decides whether it needs more or less
light and then automatically adjusts the shutter speed accordingly.
 Manual: Select this option to manually set up the Shutter (Manual) and AGC (Manual)
values.
Iris (P-Iris): Specify the size of the Iris opening here. For P-Iris setting, you have to select AES
mode and then adjust the Iris level to enable greater depth of field, and improve image
sharpness and clarity. The lower the level, the wider the Iris is opened, which allows the camera
to receive larger amount of light with shorten depth of field.
Without P-Iris Set Up With P-Iris Set Up
The object in the front is vague. Both objects in the front and back are clear.
Shutter: If enabled, this setting lets you set the shutter speed yourself (measured in fractions of
a second).
AGC: Set the Auto Gain Control limit here. The lower the AGC level, the lower the video signal
and the noise. However, the image will be darker under low-light condition with IR-off if you set
up the Iris to the maximum level.
