Napco Security Technologies, Inc
A maker of electronic security equipment, from intrusion and fire alarm systems to electronic door locks and building access control, sold under brands like Alarm Lock, Continental Access, and Marks USA. Founded in 1969 by a 22-year-old Richard Soloway, who started the company in his garage in Amityville, New York, and still leads it today. The company later bought Marks USA, a lock maker located just a mile down the road from its own headquarters.
