A variety of high-grade household electrical appliances and the valuables have for many families. However, some lawless elements are also more and more. This is seen most security awareness isnot strong enough. Causing steal phenomenon it is often seen. Therefore, more and more households in property safety is concerned about. Security has e an important topic. Infrared anti-theft alarm isa kind of intelligent alarm system, can greatly improve the safety degree of the households, effectively guarantee the residents' personal and property safety. Because infrared is not exposed to light, has strong confidentiality and secrecy, therefore in security, alert security device has been widely used, through the infrared transmitting and receiving system for sensing whether someone is breaking into, if the detected someone broke in, then the system will send out alarm sound and light alarm circuit sounds to the people to remind. The system based on singlechip AT89S52 series as the core, using the infrared emission tube and the infrared receiving tube for transmitting and receiving device, by an inverter inverting indirect control CPU chip.
