Sensor Preset—A grouping of low-level parameters related to luminosity and level
of detail in the video image. The presets are:
Normal—For interior or exterior scenes, with a lot of details and low contrasts.
Indoor—Less luminosity and details than Normal.
Outdoor—More luminosity and details than Normal.
Fluorescent—For interior scenes lit with tungsten fluorescents.
White Balance Bias—An offset (in degrees Kelvin) to adjust the colors based on
the lighting situation; possible values range from -2000 to 2000. A negative offset
adds a blue tint to the image, whereas a positive value adds redness.
Lens Type—The way the lens handles its iris aperture. The available types are
Manual and Auto Iris (DC); video-type auto-iris lenses are not supported.
Metering Zone—The area the camera uses to take its measurements. Two zones
are available: normal and backlight.
Gamma Mode—The way the IP camera changes the mid-tone contrast and
brightness of an image. The available modes are:
Auto—The camera automatically chooses the best gamma setting.
Manual—You set the gamma correction in the Gamma Manual Value box.
Off—No gamma correction is performed.
Gamma Manual Value—The value (in the 25–100 range) to correct the mid-tone
contrast and brightness of the image. The lower the value, the more brightness
and contrast is added to the image.
Normal and Backlight Metering Zones
A metering zone is the area on the image where the camera takes its measurements
for brightness and white balance. You can create two metering zones: normal and
backlight. You can specify which one to use in the Metering Zone parameter of the
Video Sensor page.
A metering zone is defined as a set of four even-numbered pixel coordinates
representing a rectangle:
In both metering zones, the following presets are available:
Coordinate Description Range
X The x coordinate of the upper right corner 0–704
Y The y coordinate of the upper right corner 0–524
W The width of the rectangle 16–720
H The height of the rectangle 16–540
