AXIS Q6054-E PTZ Dome Network Camera
Video
Increasing the
Color level
increases the color saturation. The value 100 gives maximum color saturation and the value 0 gives
minimum color saturation.
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
To change this setting go to
Setup > Video > Camera Settings
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
(WDR) processing balances the brightest and darkest sections of a scene to produce an image that is balanced
in lighting to provide more detail. Wide dynamic range can improve the exposure when there is a considerable contrast between light
and dark areas in the image. There are three different WDR modes:
WDR 1 -
contrast
WDR 2 -
double exposure
WDR 3 -
contrast and double exposure
The different WDR settings adjust for various amounts of contrast in the image. Use a higher WDR number for a higher contrast.
Enable WDR in intense backlight conditions. Disable WDR in low light conditions for optimal exposure.
Exposure Settings
Exposure control -
These settings is used to adapt to the amount of light used.
Automatic
is the default setting and it can be
used in most situations. The shutter speed is automatically set to produce optimum image quality. Use
Manual
if you have special
requirements for the exposure setting and wish to lock it. Select the desired exposure time from the drop-down list.
Max exposure time -
Shutter speed, also called ‘exposure time’ stands for the length of time the camera shutter is open, thereby
exposing the camera sensor to light. If shutter speed is fast it can freeze action effectively. If shutter speed is slow, it can cause
moving objects to appear blurred. Decreasing the exposure time will reduce motion blur.
Allow slow shutter -
Select
Allow slow shutter
to let the camera decrease the shutter speed in low light to improve image brightness.
Max gain -
Measured in decibels (dB), gain describes the amount of amplification applied to a signal, in this case the visual
information in the image. A high level of amplification may provide a better image in very low light situations. A high gain will also
increase the amount of image noise.
Exposure zones -
This setting determines which part of the image is used to calculate the exposure. For most situations, the
Auto
setting can be used. For particular requirements, select a predefined area.
IR cut filter -
The IR cut filter prevents infrared (IR) light from reaching the image sensor. In poor lighting conditions, or when
using an external IR lamp, set the IR cut filter 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 filter is off. Set the IR cut filter to
Auto
to automatically switch between
On
and
Off
according to the lighting conditions.
Day/Night shift priority -
Use the
Day/Night shift priority
bar to determine when the camera shifts into either day mode or night
mode. By default, the camera will automatically change from day to night mode at a pre-defined level which corresponds to light
conditions. By dragging the bar handle towards the sun, the camera will change to day mode earlier and change to night mode late.
