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
Wide dynamic range can improve the exposure when there is a considerable contrast between light and dark are as in the image.
Exposure Settings
Configure 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. T he shutter speed is automatically set to produce optimum image quality.
Maxexposuretime-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 incr ease 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, f or example a light bulb, causes other a reas in
the image to appear too dark.
Exposure zones - This settings determines w hich 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 a rea.
Max gain - Measured in decibels (dB), gain describes the amount of amplification applie d to a signal, in this case the visual
information in the ima ge. A high level of amplifica tion may provide a bette r image in very low light situations. A high gain will also
increasetheamountofimagenoise.
IR cut filter
The IR cut filter prevents infrared (IR) light from reaching the image sensor. In poor lighting conditions, for example a t night, o r
when using an IR lamp, set the IR cut filter to Off. This increases light sensitivity and al lows the product to “see” infrared light. The
image is shown in black and white when the IR cut filter is off.
If using automatic Exposure control,settheIRcutfilter to Auto to automatically switch between On and Off accordingtothe
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, o n page
9
. If required, the focus control can be disabled under PTZ > Advanced > Controls.
Noise reduction - Set to On to enable noise reduction. Noise reduction may increase the amount of motion blur.
ImagefreezeonPTZ-Select All movements to freeze the image while the camera is moving during a pan, tilt or zoom opera t ion.
Once the camera reaches its new position, the view from that position is shown. Presets freezes the image only when the camera
moves between preset positions.
Overlay
Overlays can be used to provide extra information and are superimposed over the video image. With overlay text it is p ossible to
incl
ude date and time or view the current bit rate as overlay text.
To include the current bit rate as overlay text go to Video > Video Stream > Overlay Settings, select the Include text check box
option, and enter the code #b in the field. See the online help
for supported formats.
