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
screen may change color or flicker. If so adjust the
shutter speed manually to [1/60] or [1/100].
∫
Manual iris/gain adjustment
≥
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.
