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.”
