Sentry Industries is a privately owned business that started in 1963. Sentry's original product line consisted of film, photo accessories and blank reel-to-reel, as well as prerecorded reel-toreel. As Sentry grew, the company began to market new products, such as it own line of four and eight track prerecorded tapes and tape players. When Philips first introduced the cassette format, Sentry Industries was the second company in the United States to sell cassettes.
In 1965, Sentry was bought by Berkey Photo and operated within the Keystone Camera Group, supplying electronics, photo and music industries throughout the United States .
In 1970, Sentry was re-acquired. At that time the company primarily sold pre-recorded tapes, tape player and car audio stereos. The Sentry brand of tape accessories was sold throughout the United States and export sales were successful worldwide.
In 1984, the company moved into other product lines. The first group of headphones brought into the line were three promotional models. At this time the accessories line was greatly expanded.
Since then Sentry has become one of the most recognized suppliers in the United States , marketing over twenty different types of promotional and mid-priced headphones, as well as numerous accessories. Outstanding packaging and our exclusive product design has become Sentry's trademark
In 1991, Sentry began developing a highly successful line of calculators that grew from three to twenty-five models. Sentry calculators are now sold through various types of retail outlets and generate strong back to school sales.
