Description
Flickering can occur when a combination of indoor and outdoor light get to the
IP camera, due to a difference in capture frequency and actual indoor lighting
frequency. Check this check box to limit the range of exposure time, which
prevents flickering.
Appears when you choose Manual from the Exposure mode drop-down menu.
To control the minimum length of time in seconds that the IP camera keeps its
iris open for each frame, drag the left slider box. To control the maximum
length of time in seconds that the IP camera keeps its iris open for each frame,
drag the right slider box.
When capturing video, the IP camera automatically selects the optimum value
between the minimum and maximum values that you configure.
If the Flickerless check box is not checked, the minimum exposure value is
1/32000 and the maximum value is 1/5. If the Flickerless check box is checked,
the minimum exposure value is 1/120 and the maximum value is 1/5.
Appears when you choose Manual from the Exposure mode drop-down menu.
To control the minimum gain of the IP camera, drag the left slider box. To
control the maximum gain, drag the right slider box. A value of 0 does not
boost the gain, so the image may appear darker in a darker environment. A
higher value increases the exposure of the image, which can cause the image
to look brighter, but can also cause the image to appear more noisy.
When capturing video, the IP camera automatically selects the optimum value
between the minimum and maximum values that you configure.
Appears only when you choose Auto from the Exposure mode drop-down
menu. Choose one of these options for the IP camera iris:
Indoor—Suitable for indoor conditions
•
Outdoor—Suitable for outdoor conditions
