Therefore, the anti-robbery and anti-fire security equipment demand increased dramatically. Against theft, looting, fires, accidents such as a gas leak detection and alarm system, their needs have become more sophisticated. A kind of intelligent alarm system for residential area is introduced. It has the function of theft-proof, performing automatic detection and automatic dial. Pyroelectric infrared sensor and Microwave sensor combined are used for theft-proof so as to realize automatic detection. Multi-sensors make the least false alarm and enhance the reliability of system. Automatic dial means that it can send help voice through public telephone switch network to the bureau. When the sensor of burglarproof detects any off normal signal, an interrupt request is sent to the MCU. Next the MCU control the interface module of telephone to accomplish off hook. According the kind of dangerous, the dialing module will automatically dial the right phone number such as 110.
