Zoom Factor
Normally, a privacy mask will be repositioned and resized to cover the masked area
whenever pan/tilt/zoom functions are used. the zoom factor allows users to hide the mask if
the zoom ratio is set lower than the original ratio.
For example, when the privacy mask is set at a certain zoom ratio (e.g. 5x), the privacy mask
will be resized when the camera is zoomed in (e.g. from 5x to 20x); however, when the cam-
era zooms out (e.g. from 5x to 2x), the privacy mask will be hidden. Select On or Off to activ-
ate or disable the Zoom Factor function. Follow the steps below to set up a privacy mask.
1. Set Switch to On and click the Set button to turn on the Privacy Mask function.
2. Select a color for the mask from the Color drop-down list and click the Set button to apply the
color setting.
3. Specify the mask a number, e.g. 17. If Zoom Factor is needed, select On to enable this function.
Then, click the Add button and a privacy mask will be displayed on the Live Video Pane on the
right.
4. To shift the mask to the intended location, move the mouse cursor to the center of the mask
and click and drag.
5. To change the shape and the size of the mask, click any edge of the mask and draw it out-
ward/inward.
6. If needed, set up Zoom/Focus/Iris.
7. Click Set button to save and apply the setting. The privacy mask will be displayed in the color
set previously.
If you want to edit the previously-set mask, input the mask number in the Mask(1~20) entry field
and click the Edit button. The camera will go to the set location and display the mask. You can then
follow Steps 4 to 6 to edit the mask.
To cancel mask editing, just click the Return button to exit the editing.
