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
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.
ª
