Black zones (or privacy zones) are designed to protect critical parts of a frame from video surveillance. These critical parts may be, for example, a door access panel or a computer keyboard. To prevent then video surveillance operator from seeing the password or any other protected information, you can "black out" the desired area, thus preventing leaks of confidential information.
Warning
Black zones cannot be used on all devices.
If a device supports black zones, then in the channel settings window the Setup Black Zones... button will be enabled. Click on the button to open the zone editor.
To create a zone, left-click with the mouse and drag to define the size of the black zone. There can be several zones. You can arbitrarily move them, change their size, and delete them.
Tip
Black zones are shown over the video in both real time mode as well as in archive recording.
