Digital Verifier Overview

JPG images and AVI video files that are exported from the Digital Video
Recorder are automatically embedded with a digital signature. Digital
signatures are a way to verify the authenticity of the images to ensure that they

have not been tampered with or edited in any way. Included on the Software
Installation DVD, supplied with the DVR, is the Digital Signature Verification
program. This program can be installed on any Windows XP or Windows Vista
computer.

Using the Digital Verifier

1.

Open the Digital Verification program by selecting Start > Programs >
HRDP > Digital Verifier > Digital Signature Verifier.

2.

Click the Browse button to load the JPG image.

3.

Enter the Site Code of the DVR that the image was originally extracted

from. (The Site Code is specified in the System Configuration Menu)

4.

Click Verify to continue or Close to close the window without verifying.

If the image has not been tampered
with, a blue square will appear around
the image with the message “Original

image file.”

If the image has been tampered with,
a red square will appear around the
image with the message “Entire

image changed or wrong SITE
CODE.”
