This rugged and reliable DVR provides the ability to record RS-170 video sources using MPEG-2 compression with transport stream (.ts) files on portable memory devices for security, ease of storage, and video analysis once your mission is accomplished. A video output allows users to selectively loop-thru any of the three video inputs. User interface with the DVR is facilitated through action buttons on the front face of the unit and an intuitive on-screen menu and encoder knob. Avalex Technologies sets the industry standard for digital video recording technology and user interface.
