Research On Intrusion Alarm And Image-Recording System

With the development of science and technology, the level of automation improves continually. Intelligent video surveillance is taking the place of human local surveillance. In recent years, video technology has been developed rapidly, and it is widely used in industry, national defense, commerce, traffic, finance, office automation and home security. In this paper, a intrusion alarm and image-record system is described, the Flash memory technology has been applied, it records the images of some certain locale and provides information for postmortem. This system has little volume and because has it's own memory chip, it can be installed and used independently.The proposed system is composed of four parts which contain human body detection module,infrared lighting source,centre control module,Wireless Communication module,alarm module. Using human body detect system based on pyroelectric infrared sensor developing digital image record and memory system, detecting the invaded people, alarm by the telephone with the Embedded CPU, the system can detect the an invader , record and storage the images of some certain locale and telephone alarm. Use CPLD to control the CMOS image sensor and the flash storage memory to record the image in the image record part. In order to enhance image gathering facility as well as the image data transmission speed, the camera has used the USB connection.
