DIGITAL VERIFIER OVERVIEW

JPG images and AVI video files that are exported from the 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 recorder, is the Digital Signature Verification
program. This program can be installed on any Windows XP, Windows Vista or Windows 7
computer.
