11.3 Watermark Viewer
The GV-System can embed digital watermarks in video streams for the purpose of authentication. The
watermarks are encrypted and digital signatures embedded in video streams during the compression
stage, protecting videos from the moment of creation. Watermarking ensures that images are not
edited or damaged after they are recorded.
The Watermark Proof is a watermark-checking program. It can verify the authenticity of the recording
before you present it in court.
11.3.1 Activating Watermark Protection
Click the Configure button on the main screen, click System Configure, click General Setting and

recorded.
