Manual shutter speed adjustment
Avoid recording under fluorescent light, mercury
light or sodium light because the color and
brightness of the playback image may change.
If you increase the shutter speed manually, the
sensitivity lowers and accordingly the gain value
increases automatically, which may increase
the noises on the screen.
You may see vertical lines of light in the
playback image of a brightly shining subject or
highly reflective subject, but this is not a
malfunction.
During normal playback, image movement may
not look smooth.
When recording in an extremely bright place,
the color of the screen may change or flicker. If
this happens adjust the shutter speed manually
to 1/60 or 1/100.
Manual iris/gain adjustment
Set the shutter speed before setting the
aperture (iris/gain) when manually adjusting
both settings.
If the value does not become “OPEN”, you
cannot adjust the gain value.
If the gain value is increased, the noise on the
screen increases.
Depending on the zoom magnification, there are
iris values that are not displayed.
