Configure the electronic shutter or electronic iris settings according to the movement and luminance level of the subject.
OFF: |
Disables the electronic shutter or electronic iris function. |
---|---|
SHORT: |
Enables the fast shutter mode. |
LONG: |
Enables the long exposure shutter mode. |
EI: |
Electronic iris |
The configured settings will be applied to “CAM1” or “CAM2”, whichever you selected under [VIEW].
The fast shutter mode has a shorter exposure time than the field storage time.
Configuring the fast shutter mode enables you to capture quick motion in the subject.
You cannot select “SHORT” to configure the fast shutter mode if the electronic sensitivity boosting ([SENSE UP] in [IRIS]) is enabled.
The available options vary depending on the model used.
VCC-HD2300P/VCC-HD2100P: |
25, 50, 120, 250, 500, 1000, 2000, 4000, 10000 |
---|---|
VCC-HD2300/VCC-HD2100: |
30, 60, 100, 250, 500, 1000, 2000, 4000, 10000 |
Each of the above shutter speed values represents the denominator “n” of the fraction 1/n. For example, selecting “500” means to set a shutter speed of 1/500 second.
The long exposure shutter mode has a longer exposure time than the field storage time.
The long exposure shutter mode increases the sensitivity of the camera to make the subject brighter.
You cannot select “LONG” to configure the long exposure shutter mode if the electronic sensitivity boosting ([SENSE UP] in [IRIS]) is enabled.
x1, x2, x4, x8, x16, x32
Each of the above shutter speed values represents a multiple of the field storage time. The higher the value, the longer the exposure time.
Setting an excessively long exposure time may result in ghosts, blurs and white spots if the subject includes any moving object.
The electronic iris controls both the AGC and the shutter speed to adjust the exposure.
If you are using an auto iris lens, the electronic iris will activate automatically at the open end of the aperture to adjust the exposure even when [SHUTTER] is set to “OFF”.
