A Mask List
This displays a list of the masks configured for the device
selected in the tree structure.
B Freeze image during PTZ movement
Select this check box when you want to stop mask
rendering during pan, tilt, and zoom movement.
If you pan, tilt, or zoom the camera while configuring a
mask area, the mask moves accordingly, but the movement
of the mask may lag somewhat behind the pan, tilt, or
zoom movement. Selecting this check box to stop mask
rendering during pan, tilt, and zoom movement allows you
to accurately configure the mask area.
C Mask Type
Select how the mask will be displayed.
Masks can be filled with a single color or a pattern.
• If you selected [Single Color], specify a fill color for the
mask in the dialog box that appears.
• If you selected a pattern, such as [Random Noise], you
can also specify a masking level.
Caution
For [Gaussian Blur] and [Mosaic], because the blur size (in
pixels) does not shift as the image is zoomed, zoom out as
far as possible before setting a mask with these patterns.
Otherwise, the mask will not be visible until the image is
zoomed in.
D Pan, Tilt, and Zoom Toolbar
This is available when the camera is equipped with
pan, tilt, and zoom functions.
Use the buttons to control the pan, tilt, and zoom of the
camera, and check whether or not the camera moves
correctly to hide a configured area.
You can also select a preset, and move the camera to
the preset position.
