WatchGuard Video has redesigned its in-car video system with a second generation of the WatchGuard DV-1, a digital police in-car video system that records onto rewritable DVD-Video discs that play in regular DVD players. The 2nd Generation WatchGuard DV-1 features a rubber-padded, welded aluminum overhead housing designed to meet Federal Motor Vehicle head impact standards, and the enclosure is streamlined, increasing external visibility. A new motherboard has been incorporated to improve reliability in extreme environments and to expand the operational temperature range from zero to 158 degrees Fahrenheit. Automatic Crash Detection has also been included which allows the system to sense a vehicle collision and automatically activate recording, including buffered pre-event video.
