Among his 500 patents are one for AC bias (1941), and U.S. #2,351,007 (filed 1942) for a recording head. He designed a wire recorder that played 30 minutes, at five feet per second, or 60 minutes at 2.5 feet per second, on 0.004 diameter stainless steel wire. General Electric manufactured it for use by the American and British military during World War II. Camras continued his influential research in video recording technology through the 1980s.
