Watermarking

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 (System Administration > Security > Display watermark with username over video), it is not possible to view and/or export video without the watermark for any user except an Administrator or Owner. You can adjust the opacity (0 – 100%) and the number of times the username is overlayed (1x1 array – 6x10 array) on the image via the Watermark Preview button.

Additionally, all exported video from an Nx Witness System contains a system-generated internal Watermark which can be used for analyzing video authenticity.
