EV Adjustment
19 steps of offset level from -9 to +9 are available to adjust the internal
reference brightness level. The higher the level the brighter the
images, and the lower the level the darker the images.

Auto Gain Control
The circuit gain is adjusted automatically between Min. and the
selected value, "Low," "Mid" and "High” where the sensitivity
characteristic increases in the order of "Low," "Mid" and "High”. Noise
at dark will be more noticeable when Auto Gain Control is near "High".

at dark will be more noticeable when Auto Gain Control is near "High".
NOTE:
If sensitivity is still too low after setting Auto Gain control, set the high
limit value of the slow shutter, to further increase sensitivity.

Shutter Speed
Default is: 1/25 s. The shutter speed is set at automatic, 1/25 s, 1/50 s,
1/120 s, 1/250 s, 1/1000 s and 1/10000 s. The network camera will
adjust the aperture according to the amount of ambient light.

adjust the aperture according to the amount of ambient light.
Slow Speed Shutter
The Slow shutter can be turned “ON” if the sensitivity is still not so
good under “High” gain condition at dark. The optimum image level can
be maintained by appropriate gain and shutter combination which are
determined automatically inside camera system.
As slow shutter activates, the exposure time becomes longer and
frame rate becomes smaller. Blurred images sometimes are prominent
with moving objects.

Back Light Compensation
Set an area for backlight compensation. If backlight compensation is
activated, the camera performs the exposure control only within the
specified area.
Backlight compensation is a function that achieves the brightness of a
selected area to an optimum image level. This function is necessary
when an auto iris lens tends to close due to an intense light coming
from the back of the object in the area to be viewed so that areas
become dark and visibility deteriorates. In this case, set the area so
that the portion to be viewed is within the selected area. The area size
is roughly as shown in Fig. 2 below.
