Overlay/Mask Settings
Overlay/Mask Type
When using an image overlay, select from the
following options the type to use:
• Uploaded image as overlay - usually used to
provide extra information in the video image.
• Uploaded image as privacy mask - conceals
part of the video image.
• Configurable areas as privacy masks - up to 3
black areas are used to conceal parts of the
video image.
The difference between an overlay and a privacy
mask is that a privacy mask cannot be bypassed
by accessing the video stream with the help of the
AXIS HTTP API, whereas an overlay can.
Selecting the overlay/mask type will display
further settings available for the selected type. See the online help for further information.
