Watermark on video

Eocortex has the ability to overlay a watermark on live and archived video. This will help to identify the source of video content leakage occurred when viewing and exporting video, as well as saving and printing a frame in the Eocortex Client application. When the watermark is enabled, the information about the user who has downloaded the video or frame will be displayed on the video and frame.

Description

Watermark option allows overlaying the camera image with information about the user who is accessing the camera. The watermark can be applied both when viewing the video in the Eocortex Client application and when exporting archive fragments and saving or printing individual frames.

Note

Overlay and display settings can be configured by the surveillance system administrator in the Eocortex Configurator application. By default, both the overlay and display options are disabled.

The watermark applies to an image as text composed as follows:

• Date and time of the device where the Eocortex Client application is running

• Name of computer

• Username of Eocortex user

Watermark can be composed of all attributes at once, or only some of them.

For the applied watermark it is possible to set the color and transparency, as well as to choose the method of text arrangement on the image as one of the following options:

• One watermark on the diagonal

• Multiple watermarks on the diagonal

• One watermark on the horizontal

• Multiple watermarks on the horizontal

Individual watermark overlay settings can be set for each camera.

The overlay settings are consistent for the camera, so the watermark will have the same appearance and structure both when viewing the video in the Eocortex Client application and when exporting the video or frames. So, even when exporting an archive for a group of cameras at once, each camera will have its own watermark according to the specified settings.

Note

If the Date and time attribute is enabled, its behavior will be different when viewing video and frames in the Eocortex Client application and exporting. So, when viewing video in the application, this attribute displays the current computer time, while in the exported video and on the saved frame it will display the time when the export process started.

Watermark overlay settings are set for the camera, so the watermark will have the same appearance and structure for all users who are defined to see it. At the same time, different groups of users can be provided with different watermark display settings in the Eocortex Client application by selecting one of the following display options:

• Only on live view

• Only on archive view

• Always

Note

If the Only on live view option is selected, the watermark will not be applied to exported archive fragments and frames saved or printed from the archive.

Watermark is compatible with the option of overlaying an image from a file.

Using in the Eocortex Client application

If the camera is set to display a watermark and the user has been given the Display watermark on video permission, the Eocortex Client application will display the watermark in the cell with the video stream from that camera both during live viewing and archive playback.

Warning

In Eocortex systems running with Enterprise and ULTRA licenses, the watermark is not visible in the Eocortex Client application and is not overlaid on exported content for users with Senior administrator access rights.

The watermark is not visible in the preview section of the Fragments mode.

When saving or printing a frame, the watermark that is currently displayed in the camera cell will be applied to an image with all lines and columns unchanged.

To watermark the exported video, go to the Archive export window and click Start export. When selecting a camera from the list of cameras, the watermark configured for that camera will be displayed on the preview.

Warning

For cameras with applied watermark, exporting the archive in the formats MCM and MP4 without time stamps, high speed is not available. If at least one camera with enabled watermark is selected when exporting an archive for a group of cameras, exporting to the specified formats will be blocked for the entire group.

The same information is available in the tooltip next to the format selection menu.

In addition to the text watermark, when exporting videos it is possible to overlay an image from a file to the lower right corner of the frame. These options are compatible with each other and can be used simultaneously. The image from the file will overlay the watermark text.
