(NAPCO), incorporated on December 3, 1971, is a diversified manufacturer of security products, including access control systems, door-locking products, intrusion and fire alarm systems and video surveillance products. The Company's products are used for commercial, residential, institutional, industrial and governmental applications, and are sold worldwide principally to independent distributors, dealers and installers of security equipment. The Company's access control systems consist of a range of identification readers, including card readers, hand scanners; a control panel; a personal computer (PC)-based computer, and electronically activated door-locking devices. When an identification card or other identifying information is entered into the reader, the information is transmitted to the control panel/PC, which then validates the data and determines whether to grant access by electronically deactivating the door-locking device.
