∫ 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 an extremely bright place, the
screen may change colour or flicker. If so adjust the
shutter speed manually to [1/50] 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.
Manual shutter speed/aperture adjustment
Shutter Speed: Adjust it when recording fast-moving subjects.
Aperture: Adjust it when the screen is too bright or too dark.
