AXIS P5534 PTZ Dome Network Camera
Video and Audio
Image Appearance
Increasing the
Color level
increases the color saturation. The value 100 gives maximum color saturation. The value 0 gives a
black and white image.
The image
Brightness
can be adjusted in the range 0–100, where a higher value produces a brighter image.
Increasing the
Sharpness
can increase bandwidth usage. A sharper image might increase image noise especially in low light
conditions. A lower setting reduces image noise, but the whole image will appear less sharp.
White balance
White balance is used to make colors in the image appear the same regardless of the color temperature of the light source. The Axis
product can be set to automatically identify the light source and compensate for its color. Alternatively, select the type of light
source from the drop-down list. For a description of each available setting, see the online help
.
Wide Dynamic Range (Dynamic Contrast)
Wide dynamic range (Dynamic Contrast) can improve the exposure when there is a considerable contrast between light and dark
areas in the image. In intense backlight conditions, enable WDR. Disable WDR In low light conditions for optimal exposure.
Note
This setting is only possible when using automatic exposure control.
Exposure Settings
Con
fi
gure the exposure settings to suit the image quality requirements in relation to lighting, frame rate and bandwidth
considerations.
Exposure control -
These settings is used to adapt to the amount of light used.
Automatic
is the default settings can be used in most
situations. The shutter speed is automatically set to produce optimum image quality.
Max exposure time -
Select the maximum exposure time from the drop-down list. Increasing the exposure time will improve
image quality, but decrease the frame rate. There may also be an increase in motion blur. Checking
Allow slow shutter
decreases
the shutter speed in low light to improve image brightness.
Enable Backlight compensation -
Enable this option if a bright spot of light, for example a light bulb, causes other areas in
the image to appear too dark.
Exposure zones -
This settings determines which part of the image is used to calculate the exposure. For most situations, the
Auto
setting can be used. For particular requirement, select a prede
fi
ned area.
Max gain -
Measured in decibels (dB), gain describes the amount of ampli
fi
cation applied to a signal, in this case the visual
information in the image. A high level of ampli
fi
cation may provide a better image in very low light situations. A high gain will also
increase the amount of image noise.
Day/Night
The IR cut
fi
lter prevents infrared (IR) light from reaching the image sensor. In poor lighting conditions, for example at night, or
when using an IR lamp, set the IR cut
fi
lter to
Off
. This increases light sensitivity and allows the product to “see” infrared light. The
image is shown in black and white when the IR cut
fi
lter is off.
If using automatic
Exposure control
, set the IR cut
fi
lter to
Auto
to automatically switch between
On
and
Off
according to the
lighting conditions.
Image settings
Autofocus enabled -
Automatic focusing is enabled by default. If the focus position is changed manually using the focus bar,
autofocus will be disabled even if enabled here. In this case, use the PTZ control panel to enable autofocus, see
PTZ Controls, on page
10
. If required, the focus control can be disabled under
PTZ > Advanced > Controls
.
