AXIS P1346 Network Camera
Video and Audio
White balance
White balance is used to make colors in the image a ppe ar 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 ea ch available setting, see the online help
.
Wide Dynamic Range (Dynamic Contrast)
Wide dynamic range (D ynamic 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
Configure the exposure settings to suit the image quality req uirements in relation to lighting, frame rate and bandwidth
considerations.
Exposure value - Click in the bar to fine-tune the exposure.
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 prod uce optimum image qua lity. Flicker-free 50 or 60 Hz is used to remove
flicker which can be caused by fluorescent a nd other light sources. The Hold current option locks the current exposure settings.
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 predefined area.
Exposure priority - When Motion is prioritized and maximum Shutter time is set to a small value, motion blur in the image is
minimized. This can be useful for recognition of moving objects such as people and vehic
les. However, pr ioritizing motion may cause
an increase in image noise, especially in low light situations. When Low noise is pr ioritized and Gain is set to a small value, image
noise is minimized. The file size is reduced, which can be useful if storage space or bandwidth is limited. However, prioritizing low
noise ma y result in a very dark image, especially in low light situations.
IR cut filter
The IR cut filter 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 filte r to Off. This increases light sensitivity and allows the product to “see” infrared light. The
image is shown in black and white w hen the IR cut fi
lter is off.
If using automatic Exposure control,set
the IR cut filter to Auto to automatically switch between On and Off accordingtothe
lighting conditions.
Iris configuration
Iris configuration shows the current configured iris type. Do not change the iris configuration unless the lens has been changed,
see Replacing the lens,
on page 8 .
Iris adjustment
Select Enable automatic iris adjustment to automatically compensate for changing light conditions. This option is not available
if a fixed iris is used.
Use the Iris adjustment slider to set the preferred F-value. The scale rep resents the amount the iris is open. If set to 0, the iris
is open
edasmuchaspossible. Ifsetto100,theirisisclosedasmuch as possible. The actual F-value is shown b elow the
slider. If automatic iris adjustment is ena bled, the iris will stay at this position as long as light conditions are favorable. If light
conditions change, the iris will adjust itself to the best iris settings. If automatic iris adjustment is disabled, the iris will lock on
th
e set position regardless of light conditions
