About the Iris F-number
Blurry effects due to “small aperture diffraction”
may occur when the diameter of the iris becomes
too small. You are therefore recommended to use
the camera in an environment that does not require
you to narrow the iris excessively.
Setting the Gain
This function electrically boosts the light sensitivity
when there is insufficient illumination on the object.
You can set the gain of the video amplifier
according to the brightness of the object. Select the
setting mode according to your shooting
