A Shutter speed:
1/60 to 1/8000
VDR-D300 1/30 to 1/2000
VDR-D250 1/30 to 1/500
≥ The shutter speed closer to 1/8000 is faster.
B Iris/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
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.
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.
