Manual shutter speed adjustment
≥Avoid recording under fluorescent light, mercury
light or sodium light because the colour 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 the extremely bright place,
the colour of the screen may change or flickers.
If so adjust the shutter speed manually to 1/50
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.
