Developing Closed Circuit Television

Abstract

This thesis is about development of Closed circuit television (CCTV) which places an important role in building operations and the protection of property and people. The main function of the CCTV system is to allow remote viewing (typically from several cameras back to one location within the same building) and surveillance. It is typically part of an overall integrated package operated by security personnel that includes access control, alarms, intrusion detection, and communications. A typical CCTV system will include, cameras, a transmission medium (i.e. coaxial, fiber-optic, twisted-pair), video switcher, multiplexer, display monitors and DVR. The CCTV systems are widespread all over the world, especially at the airports, hospitals and banks. The thesis cover all the parts of the CCTV system, giving a detailed information, and at last including a practical control circuit with a program in C language controlling a camera through the parallel port of a PC.
