If you want to use your video evidence in court, you can enable video watermarking on the Archiver to protect the video against tampering and prove that it was not altered.

What you should know

Video watermarking adds a digital signature (watermark) to each recorded video frame to ensure its authenticity. If the video is later changed by adding, deleting or modifying a frame, the signatures for the modified content will no longer match, showing that the video has been tampered with.


  1. Open the System task and click the Roles view.
  2. Select the Archiver role, click the Resources tab, and click Advanced settings.
  3. Set Video watermarking to ON, and click OK > Apply.
  4. Set up an encryption key for the watermarking fingerprint.
