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 the 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
≥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.
