近年来，随着改革开放的深入发展，电子电器的飞速发展.人民的生活水平有了很大提高。各种高档家电产品和贵重物品为许多家庭所拥有。然而一些不法分子也是越来越多。这点就是看到了大部分人防盗意识还不够强.造成偷盗现象屡见不鲜。因此，越来越多的居民家庭对财产安全问题十分担忧。

报警器这时正为人们解决了不少问题.但是市场上的报警器大部分都是用于一些大公司财政机构。价格高昂,一般人们难以接受。如果再设计和生产一种价廉、性能灵敏可靠的防盗报警器，必将在防盗和保证财产安全方面发挥更加有效的作用。由于红外线是不见光，有很强的隐蔽性和保密性，因此在防盗、警戒等安保装置中得到了广泛的应用，此外，在电子防盗、人体探测等领域中，被动式热释电红外探测器也以其价格低廉、技术性能稳定等特点而受到广大用户和专业人士的欢迎。  

 recent years, along with reform and open policy thoroughdevelopment, electronic electric appliance's swift development.People's living standard had the very big enhancement. Each kind ofupscale electrical appliances product and the valuables have formany families. However some unlawful elements are also more andmore. This sees majority of person security consciousness alsoinsufficient. Creates steals the phenomenon to be common.Therefore, more and more resident families worried to the propertysecurity problem. the alarm apparatus had been solving manyproblems by now for the people. But in the market alarm apparatusmajority of use in some big company fiscal institution. The priceis soaring, generally the people accept with difficulty. Ifredesigns and produces one kind moderately-priced, the performancekeen reliable burglar alarm, will certainly plays a more effectiverole in security and the guarantee property security aspect.Because infrared is unexposed, has the very strong confidentialityand the secrecy, therefore in security, security installments andso on security obtained the widespread application, in addition, inelectron security, domains and so on human body survey, the passiveformpyroelectric infrared acquisition aid also by its low inprice, the technical performance stable and so on characteristicsreceives the user community and professional's welcome. 
