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
. If required, the focus
control can be disabled under
PTZ > Advanced > Controls
.
Defog -
Select this feature to counter the effects of foggy weather and get a clear image.
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.
About overlays
Overlays are superimposed over the video stream. They are used to provide extra information during recordings, such as a timestamp,
or during product installation and configuration.
About overlay text
An overlay text can include the current date and time, or a text string. When using a text string, so-called modifiers can be used to
display, for example, the current bit rate or the current frame rate.
You can choose between the following text overlay sizes:
