Exposure
Figure 3 - 7: Exposure Settings
 Type
Exposure modes control the light intensity of picture. There are four modes, Manual, AES (Automatic
Electronic Shutter), ALC, and Flickerless, for adjustment depending on conditions. When in Manual
mode, Shutter Speed is adjustable.

EV Compensation
Available only in Full Automatic mode, EV adjustment is the exposure compensation telling the unit by
setting the value from -2 to 2 with intervals of 0.5 for
scenes to be either darker or brighter.
 Day &Night
Set DAY/NIGHT function. Move the cursor to select Auto/Color/BW mode. If selected Color mode, the
unit is forced the unit to stay in DAY(COLOR) mode all day; if BW, in BW (NIGHT) mode all day.

Switching Sensitivity
Switching Sensitivity: To determine the sensitivity of the day/night mode switching mechanism. High
represents camera is prone to auto switch between day/night mode for minor light intensity change. On
the other hand, Low indicates camera is going to switch between day/night mode on the basis of major
changes of surrounding light intensity.
 Delay Time
To set the delay (buffered) time for switching between day/night mode. Fast means camera instantly
switch with nearly no delay time between day/night mode. And Slow stands for camera has a longer
delay buffered time prior to switching between day/night modes.

Slow Shutter
Slow Shutter can be enabled if the sensitivity is still not good enough under “High” gain condition in the
dark. Optimal image level can be maintained by appropriate gain and shutter combination that
determined automatically inside the unit system. Slow Shutter can be selected from OFF, 1/30, 1/15, and
1/7.5 when camera type is set to NTSC, and 1/25, 1/12.5, and 1/6.25, when PAL. As slow shutter
activates, the exposure time becomes longer and frame rate becomes smaller, and moving objects may
result in blurred images.
