Shutter Priority Mode
In this mode, the shutter speed takes main control of exposure. The range of shutter speed is
from 1/10000 to 1/30.
P-Iris Mode
In this mode, the exposure is automatically adjusted but the aperture will not exceed the
value selected (F4.8 to F9.6). If the IP Speed Dome is exposed to bright light at times, setting
a maximum iris value (minimum aperture size) will prevent blurring when the aperture size is
too small.
Iris Priority Mode
In this mode, the iris setting has priority in control of exposure and the aperture will be fixed
at the value selected. The value of iris is adjustable from F1.6 to F28.
