AXIS P5532 PTZ Dome Network Camera
Video and Audio
Noise reduction - Set to On to enable noise reduction. Noise reduction may increase the amount of motion blur.
Stabilizer - When monitoring environments that are subject to vibrations (e.g. traffic control), images may appear to be unsteady. Select the frequency, High or Low, that gives the best improvement in image quality. Enabling the stabilizer will limit the digital
zoom. See the online help 
for more information.
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.

The Privacy Mask List, Video & Audio > Privacy Mask, shows all the masks that are currently configured in the Axis product and indicates if they are enabled.
The Pan/Tilt/Zoom coordinates of the privacy mask are locked in their position. This means that regardless of the angle and zoom of the lens, the same place or object will be hidden. To define at what magnification the mask should be displayed, zoom to the desired level and click Set level.
