Server based Privacy mask


This feature is introduced in VDG Sense 2.7.3


The server based Privacy Mask feature allows the user to configure up to 64 privacy zones over the videostream of the camera.

By design, the privacy masks are not shown in a layout when a administrator user is logged in. Administrator users are privileged to see the video data without privacy masking. Normal users can have an additional privilege function called ‘Lift Privacy Mask’ to be able to lift the privacy mask. This functionality can be added in the Usermanagement->Functions tab.

To enable the Privacy Mask check the ‘Enabled’ checkbox in the upper right corner. Once enabled, the buttons to create and remove the zones will become visible on the left side of the screen. When enabling the privacy mask for the first time, automatically the first zone will be added.

Additionally, the privacy mask can be enabled/disabled per zone via a macro. For this, you can use the Device->{DeviceName}->EnablePrivacyMask action.


Use ‘Enable’ to turn the feature on or off

For serverside privacy mask, you can use the ‘Preview privacy mask’ checkbox to see the effects of the privacy zone in the video.

If the camera supports camera based privacy masks as well, then a dropdownlist will be shown here where you can choose between camera based and server based privacy masks. If camera based is selected, there will be no possibility for an admin user to lift the privacy mask.

Possible blurring types:

  • Opaque color

  • Pixelized

  • Haze

For both Pixelized and Haze a amount of blurness can be increased or reduced by moving the ‘Radius’ slider.
