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.
