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, at night for
example, and/or 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.
Use backlight compensation
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.
5.2.3 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 the
same, compensating for the different colors present in different light sources.
