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.
a. Shutter speed . 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.
b.
Slow shutter
. If the SLOW SHUTTER is set to ON, the shutter speed will automatically slow down to extend exposure
time during low lighting conditions to obtain clearer image.

the scene illumination.
