WatchGuard Video has completed and release a major software upgrade for its DV-1. The WatchGuard DV-1 is a digital police in-car video system that records directly to rewritable DVD-video discs that play in regular DVD players. WatchGuard DV-1 customers will receive the new, third generation firmware in the form of a CD that will completely upgrade existing installed systems. The third generation DV-1 includes a new DVD authoring system that allows compatibility with older DVD players not designed to support rewritable media. In addition to a dozen new features, detection and automatic handling of DVD write errors have been added, and the overall system speed has increased.
