WatchGuard Video releases Version 5.0 programming for the WatchGuard DV-1 digital in-car video system. The new system firmware is being provided free of charge to every WatchGuard customer by CD. Upgrading the WatchGuard DV-1 is done by simply loading the CD and the new programming applies to both first and second generation DV-1 camera systems. 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 new 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 adds many other features including a new fully-automatic Night Mode, a Covert Recording Mode, and Event Tags that support the new WatchGuard Critical Event Server software.
