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.

Hi Lee,
Yes, just connect the drive to the other client and navigate to the folder with the local settings menu.
