安(an)(an)防是(shi)(shi)個比較籠統(tong)(tong)的概念。從廣義(yi)上(shang)來說，安(an)(an)防就是(shi)(shi)為保(bao)護人的人身和財產安(an)(an)全而(er)采取手段與工具，也屬于安(an)(an)防的基本(ben)內涵。從狹(xia)義(yi)上(shang)來說，安(an)(an)防則是(shi)(shi)由(you)多個監測、檢測和預防的系(xi)統(tong)(tong)組成，其中(zhong)包括閉路監控系(xi)統(tong)(tong)、防盜報警(jing)系(xi)統(tong)(tong)、樓宇對講系(xi)統(tong)(tong)、停車廠管理系(xi)統(tong)(tong)、小區(qu)一(yi)卡通系(xi)統(tong)(tong)、紅(hong)外(wai)周界報警(jing)系(xi)統(tong)(tong)等共12個系(xi)統(tong)(tong)。可以說，我們沒(mei)有過多接觸有關(guan)安(an)(an)防的信息，但它卻(que)無時無刻(ke)不在我們身邊。因此，了解和掌(zhang)握相關(guan)的安(an)(an)防品牌知識也是(shi)(shi)很(hen)有必要的。

安防(fang)(fang)系統比較復雜，所(suo)以(yi)安裝同樣也是(shi)個大工(gong)(gong)程。有的安防(fang)(fang)工(gong)(gong)程造(zao)價甚至(zhi)高昂，一(yi)般(ban)多是(shi)博(bo)物館、展覽館等，當然所(suo)使用的科技也是(shi)最先進的。不(bu)同的安防(fang)(fang)工(gong)(gong)程師所(suo)設計和安裝的方案和效果都有所(suo)不(bu)同，所(suo)以(yi)不(bu)同工(gong)(gong)程師或公(gong)司的報價也會有所(suo)不(bu)同，所(suo)以(yi)選(xuan)擇安防(fang)(fang)工(gong)(gong)程安裝公(gong)司時(shi)一(yi)定(ding)需要(yao)貨比三家，仔細研究(jiu)效果和方案的好(hao)壞再(zai)決議(yi)，萬(wan)不(bu)可只看(kan)品牌了事(shi)。當然，好(hao)品牌自然也不(bu)容易(yi)作假，安防(fang)(fang)設備的質量也是(shi)很(hen)有保(bao)障(zhang)的。
