areas appear simultaneously in the field of view, the WDR function can balance the brightness level of the entire image and provide
clear images with details.
4.3.7 TASK 7. Configure iris, gain and shutter speed
Setting the AE mode. AE mode defines the priority of the iris, shutter and gain when the camera adjusts the brightness of
•
the video. The options in AE MODE are as follows:
AUTO: Auto iris, auto shutter and auto gain. The camera adjusts these values automatically responding to the lighting
conditions. This is the default mode.
MANUAL: In MANUAL mode, you can adjust the shutter, iris and gain values.
Setting the iris value. To adjust the iris size for light entering the lens, you can set the IRIS value manually according to light
•
conditions. The iris value ranges from 0 (closed) to 17 (fully open).
Setting the gain. The value of gain indicates the degree of amplification of the original light signal. You can set the value
•
from 0 to 15.
Setting the shutter speed. 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 camera, and you can also enable the slow shutter
function for low lighting circumstances.
If you set the SHUTTER value larger, the shutter speed is faster. The value indicates the inverse of the shutter speed (1/value
seconds). At faster speeds, the amount of light entering the lens is less causing the image to be darker. You can set the shutter
value to 1, 2, 4, 8, 15, 30, 50, 125, 180, 250, 500, 1000, 2000, 4000 or 10000.
