Download of Uniden WDVR 1.13.1 for Mac was on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The program lies within System Tools, more precisely Device Assistants. This free software for Mac OS X is an intellectual property of Uniden.
From the developer:
Uniden WDVR is designed to give you full control and live viewing of your Uniden WDVR system cameras. All four cameras can be viewed simultaneously in quad view. However, you can double-tap on the camera you would like to view in full screen mode. You have full control of system settings, including recording parameters and video resolution and quality.
