About Cypress Computer Systems, Inc.
Cypress Computer Systems Inc. is the industry leader in the design and manufacture of access control and security (AC/S) related products. Founded in 1983, in Ft. Lauderdale, Florida, the company founders first used their extensive technical experience in the industrial data communications industry to develop a wide-area proprietary alarm monitoring system known as Cypress AMS.

Since the installation of the first AMS system at General Motors in 1985, Cypress's product line has evolved to encompass many aspects of security and access control. By the early 90's, the product line consisted of Alarm Monitoring, Access Control, and Fuel Management systems. Cypress also developed a variety of ancillary products which are sold as add-ons to other security manufacturers' equipment. In 1992, Cypress relocated to Michigan to better service major customers in that region such as GM, Chrysler, Ford, and EDS.

Today, Cypress products are used worldwide for a variety of AS/C functions, including parking lot gate controllers, remote buildings, crossing open building complexes, elevator shafts, and more.

Cypress remains wholly owned by the founders, Anthony J. Diodato and Jeffrey J. Roberts, and remains committed to developing state-of-the-art solutions for the access control and security industry.
