Recording
BIris/Gain value:
CLOSE # (F16 to F2.0) # OPEN # (0dB to 18dB)
≥Value closer to [CLOSE] darken the image. ≥Value closer to [18dB] brighten the image. ≥When the iris value is adjusted to brighter than
[OPEN], it changes to the gain value.
To restore to automatic adjustment
Set the AUTO/MANUAL/FOCUS switch to
AUTO.
≥When setting both the shutter speed and the iris/gain value, set the shutter speed and then set the iris/gain value.
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
gain value will increase automatically depending on how much the sensitivity lowers and the noise on the screen may increase.
≥When recording still pictures, we recommend setting the shutter speed to 1/500 or less for even more beautiful pictures.
≥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.
