• PTL (push-to-lock) white balance. WB is fixed at the moment the
DIP switch it set to ON.
Backlight compensation (BLC)
The backlight compensation function improves image quality when the
background illumination is high. It prevents the object in the center
from appearing too dark.
AI/AE exposure
Use this setting to select the method the camera uses to adjust to
different light levels. Use the Automatic Iris (AI) setting to fix the iris
value at F1.6. Use Auto Exposure (AE) setting to automatically set the
proper exposure according to the existing light conditions.
Day/Night
This function controls whether the camera is in automatic day/night
mode or forced into night mode. When set to Auto Day/Night mode,
the camera produces high-quality color video during the day or when
light levels are high. It then switches to monochrome and removes the
infrared filter to improve IR sensitivity at night or when light levels are
low. Black and white mode forces the infrared filter to stay removed
therefore the camera stays in black and white mode.
Resolution
High resolution produces higher quality images but also increases the
file size of the video images.
Flickerless control
Flickerless control eliminates the flicker caused by the differences
between the frequencies (60 Hz) of the ionization of the gas in a
fluorescent light bulb with that of the vertical frequency (59.95 Hz) in
the camera. Although the difference is very small, it results in a slight
flicker at the top of the monitor scene or, in video over IP applications,
it would be interpreted as motion. Flickerless control helps reduce the
file size and transfer bit rates of compressed video images.
