Nx Witness User Manual

To deter unauthorized or unwanted distribution of video recordings, it is possible to add a watermark to video playback. The watermark consists of the User login as a semi-transparent overlay repeated across the entire image. When enabled, only users with administrator or power user permissions can export video without the watermark.

To Enable Watermark on Exported Video

1.Open System Administration.

2.In the Security tab, enable the Display watermark with username over video checkbox.

3.Click on the Watermark Preview button to adjust the opacity (0 – 100%) and the number of times the username is overlayed (1x1 array – 6x10 array) on the image.

4.Click OK to accept or Cancel.

Note: Video still can be exported without a watermark via the Web Admin, for example. However, the Audit Trail of User Actions can be used to trace the recording event and the responsible user.
