5.4 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 its creation. Watermarking

ensures that an image is not edited or damaged after it is recorded. To enable the watermark

function, see [Watermark], 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.

5.4.1 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 on the Live View window (No. 6, Figure 3-4) to start recording

on the local computer.

5.4.2 Running Watermark Proof

1. Install Watermark Proof from the Software DVD. After installation, a WMProof icon is

created on your desktop.

2. Double-click the created icon. The Water Mark Proof window appears.

3. Click File from the menu bar and select Open and locate the recording (.avi). The

selected recording is then listed on the window. Alternatively, you can drag the recording

directly from the storage folder to the window.

4. If the recording is unmodified, a check will appear in the Pass column. On the contrary, if

the recording is modified or does not contain watermark during recording, a check mark

will appear in the Failed column. To review the recording, double-click the listed file on

the window.
