AXIS Q6042-S PTZ Dome Network Camera
Video
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.
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 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.
Image Settings
Important
The autofocus behavior is affected by factors such as light conditions, contrasts in the scene, and objects moving in and out. In
these conditions or scenes, a manual focus could be preferable to enhance performance and allow the camera to focus faster.
Autofocus enabled -
Autofocus enables the camera to focus although the distance to different objects of interest is constantly
changing. Whenever the camera’s pan/tilt/zoom position is changed, the autofocus performs a search to find the ideal focus point.
Automatic focusing is enabled by default. If the focus position is changed manually using the focus bar, autofocus will be disabled
even if enabled in
Image Settings
. In this case, use the PTZ control panel to enable autofocus, see
page 14
. 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.
Image freeze on PTZ -
Select
All movements
to freeze the image while the camera is moving during a pan, tilt or zoom operation.
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.
