Overlay/Mask Settings
Overlay image
Text, date and
time overlays
Text Overlay
These settings enable you to place text at
the top or bottom of an image, e.g. date,
time or some other text.
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.
• Configurable areas as privacy masks - up to 3 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 VAPIX 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.
