FPGA Based Security System

Security and power efficiency is the most important thing in present day situation. Need of security and saving of power is increasing rapidly. Security system becomes the best solution to overcome the intrusion problem. This project focuses on the security system which is controlled using FPGA programmed by VHDL language. Field Programmable Gate Array (FPGA) delivers breakout performance capacity and most power efficient system integration while optimizing to develop FPGA devices based on CAD tools in the Hardware Description Language (HDL). The overall project is divided into two parts. The first part is concerned with the hardware development. The second part is based on software programming to operate the hardware structure. PIR motion detectors are most frequently used for security devices. Surveillance is the monitoring of the location, behaviour or activities for the purpose of directing, managing and detecting intrusion by means of electronic equipment. Passive IR motion detectors are usually designed to provide an indication to an alarm panel in response to detecting IR that is indicative of motion of the object. The alarm panel is responsive to receipt of the breach indication to cause an alarm condition to occur. PIR motion detectors are commonly used in conjunction with indoor or outdoor to turn on a light in response to a person moving in the field of view monitored by the motion detector. PIR sensor is capable to detect motion while the programmed FPGA is capable to control the whole operation of the security system.
