Applied to both gerneration 1 and 2 DV-1 camera systems, upgrading the WatchGuard DV-1 with Version 5.0 programming is done by simply loading provided CD. After the upgrade, DVD-Video discs recorded by the WatchGuard DV-1 camera system will contain 128-bit encrypted information that is embedded into the video stream. The WatchGuard DVD Manager Utility 3.0 software program can reveal if the video on the DVD has been modified since it was originally recorded. Encrypted discs will still play on regular DVD players, but the scheme makes re-writable media absolutely secure, and provides a tool to prove in a court of law that the video recorded is original and unaltered. Version 5.0 also includes a fully-automatic Night Mode, a Covert Recording Mode, and Event Tags that support the WatchGuard Critical Event Server software. Event tags allow officers to identify recordings by the type of event, suspect gender, race, license number, case numbers and more which allows users to organize, search, and report on all video events checked in to the server. In addition to improved system performance, Version 5.0 more efficiently manages system memory and files, and improves DVD-Video authoring to increase playback reliability.
