Flickerless check box
Appears when you choose
Manual
from the Exposure mode drop-down menu.
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.
Exposure time slider
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.
