They start to pay attention to the safety of living environment. However, comfortable environment is not the only one requirement of the houses because people prefer a safer one.??Yet, the fast economic growth of China has adverse effects on the society, such as the widening income gap between city and countryside as well as the larger number of floating population. Consequently, people hope they can own a safer accommodation as thievery and burglary increasingly happened. They prefer houses with alarm system which can send alarms to the owner?and?scare the burglaries away when they intrude into houses?which?are detected.?The alarm system guarantees residents’ property safety so that they can live a more?safer life. Some domestic?manufacturers in security industry think highly of the alarm system and they start to develop automatic alarm system.?Thus many kinds of the alarm systems begin to entrance the market. However, many alarm systems are in poor reliability and in low cost performance.??This article mainly introduces the design process of the pyroelectric infrared burglar alarm, which helps people to know the alarm system, and proposes?some?present-stage development strategies and?reveal itsapplication prospect of?the?alarm system.
