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.
6.4.1 Accessing AVI Files
To verify watermark, first you have to access the recorded AVI files by one
of these methods:
1. Use
the
File Save
function (No.6, Figure 3-3) to start recording on the
local computer.
2. Use
the
Act as FTP Server
function to download AVI files from the
camera. See
4.4.2 FTP
.
3. Use the files recorded on the memory card. Since the files saved on
the memory card are of Linux file system, remember to run
Ext2Fsd
program
for Windows-based system to read and access Linux-based
files. For the instructions, see
5.2.1 Playback from the Memory Card
.
