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 12. 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.

Overlay Image
An overlay image is a static image superimposed over the video stream. The image, for example a company logo, is used to provide extra information or to mask a part of the image.
Since it is static, the position and size of an overlay image will remain the same regardless of resolution and Pan/Tilt/Zoom movements. Use a privacy mask to set up a dynamic mask which will always mask the specified part of monitored area.
For more information about privacy masks, see Privacy Mask on page 23.
To use an overlay image, the image must first be uploaded to the Axis product. The uploaded image should be a Windows
