6.4 Verifying Watermark
The watermark is an encrypted and digital signature embedded in the
video stream during the compression stage, protecting the video from the
moment of creation. Watermarking ensures that an image is not edited or
damaged after it is recorded. To enable the watermark function, see
[Watermark Setting],
4.1.1
Video Settings
.
The
Watermark Proof
is a watermark-checking program. It can verify the
authenticity of the recording before you present it in court.

To verify watermark, first you have to access the recorded AVI files by one
of these methods:
1. Use
the
File Save

local computer.
2. Use
the

camera. See

files. For the instructions, see
5.2.1 Playback from the Memory Card
