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 unit is the Digital Signature Verification program.
This program can be installed on any computer and loads an image in question.
Installing the Digital Verifier
1. Insert the Software Installation CD into the CD-ROM. (Do not install on the DVR unit.)
2. Select the Digital Verifier option to begin installation. When the Welcome screen appears, click Next.
3. When the Setup Complete window appears click Finish. Installation is complete.

originally extracted from. (The Site Code is specified in the

window without verifying.
If the image has not been tampered with, a blue square will
