摘要

Since the 1980s, in-car video cameras have been used in police vehicles to improve officer safety, enhance agency accountability, and assist in securing prosecutions. Boosted by more than $21 million in grants from the U.S. Department of Justice's Office of Community Oriented Policing Services (COPS) between 1994 and 2004, the number of in-car cameras deployed by state police and highway patrols has increased significantly over the past fifteen years.rnWith video cameras becoming a standard feature in law enforcement vehicles across the United States, breakthroughs in digital technology have resulted in important advancements in the ability to record, store, and even search video evidence. The entire video product market, from professional broadcast camcorders to consumer point-and-shoot cameras, has made the transition from analog to digital, and the trend has extended to in-car video systems.rnThe benefits of switching to digital in-car video systems are evident in the recent experience of the Lewisville, Texas, Police Department. Lewisville, a city of 94,000 people located 15 miles north of Dallas, used analog video cameras in their vehicles for years. But the video evidence obtained from these cameras came at the expense of demands on manpower and time for the department's 139 officers.
