安(an)(an)防是(shi)個比較籠統(tong)(tong)(tong)的(de)概念。從廣義上來說，安(an)(an)防就是(shi)為保(bao)護人的(de)人身(shen)和(he)財產安(an)(an)全而采取手段與工具，也(ye)屬于(yu)安(an)(an)防的(de)基本內涵。從狹義上來說，安(an)(an)防則是(shi)由多(duo)(duo)個監測、檢測和(he)預防的(de)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)組成(cheng)，其中(zhong)包括(kuo)閉路監控(kong)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)、防盜報警系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)、樓宇(yu)對講系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)、停車廠管(guan)理系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)、小區一卡通系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)、紅(hong)外周界報警系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)等共12個系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)。可以說，我們沒有(you)過多(duo)(duo)接觸有(you)關安(an)(an)防的(de)信息，但(dan)它卻無時無刻不(bu)在我們身(shen)邊。因此，了(le)解和(he)掌(zhang)握相關的(de)安(an)(an)防品(pin)牌知識也(ye)是(shi)很有(you)必要的(de)。

安防(fang)(fang)系統比(bi)較復雜，所以安裝同樣(yang)也是個大工(gong)(gong)程。有(you)(you)(you)的(de)(de)安防(fang)(fang)工(gong)(gong)程造價甚(shen)至高昂，一般(ban)多(duo)是博物(wu)館(guan)、展覽館(guan)等，當(dang)(dang)然所使用的(de)(de)科技(ji)也是最先進的(de)(de)。不(bu)(bu)同的(de)(de)安防(fang)(fang)工(gong)(gong)程師所設計和(he)安裝的(de)(de)方案(an)和(he)效(xiao)果都(dou)有(you)(you)(you)所不(bu)(bu)同，所以不(bu)(bu)同工(gong)(gong)程師或公司的(de)(de)報價也會有(you)(you)(you)所不(bu)(bu)同，所以選擇安防(fang)(fang)工(gong)(gong)程安裝公司時(shi)一定需要貨比(bi)三家，仔(zi)細研究效(xiao)果和(he)方案(an)的(de)(de)好(hao)壞(huai)再決議，萬不(bu)(bu)可只看品(pin)牌(pai)了(le)事。當(dang)(dang)然，好(hao)品(pin)牌(pai)自然也不(bu)(bu)容易作假，安防(fang)(fang)設備(bei)的(de)(de)質量也是很有(you)(you)(you)保障的(de)(de)。
