Slow shutter mode
For
low light conditions
, turn on slow shutter mode.
Max AGC Gain
For
low light conditions
, set this value to a higher value such as 30dB.
DC-Iris Control
Disable the DC-Iris lens setting when focusing the lens.. Follow the instructions in
Chapter 2.3, and enable the DC-Iris when finished.
BLC Control (Back Light Compensation)
The BLC compensates the exposure of scenes with strong back light in the central bottom
part of the image.
When the image background is too bright, or the subject too dark, backlight compensation
makes the subject appear clearer. The settings for
low light behavior
determine how the
camera behaves at low light levels. These settings affect video image quality and it
basically measures how much noise is allowed in the video images.
5.2.2 Day & Night Control
Day & Night Mode
Auto/On/Off
- Set this filter to OFF to allow the camera to 'see' infrared light, removing the
IR cut filter, when using an infrared lamp. This makes the image clearer. If set to Auto,
the camera will automatically switch between IR cut filter On and Off, according to the
current lighting conditions.
5.2.3 White Balance Control
WB Mode
ON: ATW (Automatic White balance)
OFF: MWB (Manual White balance)
The White balance adjustment setting is used to make the colors in the image appear
consistent, compensating for the different colors present in different light sources.
The GANZ ZN-Cx Network Camera could be set automatically to identify the light source
used and compensate for its color. If necessary, the type of light source could be set
manually.
The configuration of the video image would affect the camera’s overall performance,
depending on how it is used and on the available bandwidth. Setting a higher resolution
and lower compression improves video image quality but increases the amount of
bandwidth used.
