AE mode defines the priority of iris, shutter and gain when the speed dome adjusts the
brightness of the video.
The options in AE MODE are as follows:
AUTO: Auto iris, auto shutter and auto gain. The speed dome adjusts these values
automatically responding to the lighting conditions. It is the default mode.
HAUTO: You can adjust the video brightness with IRIS+ and IRIS- buttons when you select
this mode.
IRIS: It is the iris-priority mode. You need to adjust the iris value manually. The shutter and
gain values will be adjusted automatically according to the lighting conditions.
Please define the iris value according to related content in this section after you choose IRIS
mode.
SHUTTER: It is the shutter-priority mode. You need to adjust the shutter value manually. The
iris and gain values will be adjusted automatically according to the lighting conditions.
Please define the shutter speed value according to related content in this section after you
choose SHUTTER mode.
MANUAL: You need to adjust the shutter, iris and gain values manually when you select this
mode.
Please define the iris, gain and shutter speed according to related content in this section if
you choose MANUAL mode.
Setting the iris value
Purpose:
To adjust the iris size for light entering the lens, you can set IRIS value manually according to
light conditions. The iris value ranges from 0 to 17.
Note: Iris is fully closed at value 0 and fully open at value 17.
Setting the gain
The value of gain indicates the amplification degree of the original light signal. You can set the
value from 0 to 15.
Setting the shutter speed
Purpose:
The speed of the electronic shutter controls the amount of light entering the lens in a unit of
time (a second). You can manually configure the shutter speed for the speed dome, and you can
also enable the slow shutter function for low lighting circumstances.
(1) Shutter speed. If you set the SHUTTER value bigger (shutter speed is faster), the amount of
entering light per second is fewer, and the image is darker. You can set it as 1, 2, 4, 8, 15, 30,
50, 125, 180, 250, 500, 1000, 2000, 4000 or 10000.
Note: The value of X indicates that the shutter speed is 1/X second.
(2) Slow shutter. You can set the SLOW SHUTTER value as 0, 1, 2, 3, 4 and 5.
Task 3: Configure the zoom settings.
Setting the zoom limit
Purpose:
Zoom limit is a user-defined limitation of the zoom amount.
Steps:
(1) Move the cursor to ZOOM LIMIT using the direction buttons and click IRIS+ to enter.
