安(an)防是個比較籠統(tong)(tong)(tong)的概念。從廣義(yi)(yi)上來(lai)說(shuo)(shuo)，安(an)防就是為(wei)保護人的人身(shen)和財產安(an)全而采取手(shou)段與工具，也屬于安(an)防的基本內涵。從狹義(yi)(yi)上來(lai)說(shuo)(shuo)，安(an)防則是由多(duo)個監(jian)測、檢測和預防的系統(tong)(tong)(tong)組成，其中(zhong)包括閉路(lu)監(jian)控系統(tong)(tong)(tong)、防盜報警系統(tong)(tong)(tong)、樓宇對講系統(tong)(tong)(tong)、停車(che)廠管(guan)理系統(tong)(tong)(tong)、小區一(yi)卡通系統(tong)(tong)(tong)、紅外周界報警系統(tong)(tong)(tong)等(deng)共(gong)12個系統(tong)(tong)(tong)。可以說(shuo)(shuo)，我(wo)們沒有(you)過多(duo)接(jie)觸有(you)關(guan)安(an)防的信息，但它卻無(wu)時無(wu)刻(ke)不在(zai)我(wo)們身(shen)邊。因(yin)此，了解和掌(zhang)握相關(guan)的安(an)防品牌(pai)知(zhi)識也是很有(you)必要的。

安(an)(an)防(fang)(fang)系統比較復雜，所以(yi)安(an)(an)裝同樣也(ye)(ye)是個大工(gong)(gong)程。有(you)的安(an)(an)防(fang)(fang)工(gong)(gong)程造價(jia)甚(shen)至高昂，一般多是博物(wu)館、展覽館等，當然(ran)(ran)所使(shi)用的科技也(ye)(ye)是最先進的。不(bu)同的安(an)(an)防(fang)(fang)工(gong)(gong)程師(shi)所設計和安(an)(an)裝的方案和效(xiao)果(guo)都有(you)所不(bu)同，所以(yi)不(bu)同工(gong)(gong)程師(shi)或公司的報(bao)價(jia)也(ye)(ye)會有(you)所不(bu)同，所以(yi)選擇安(an)(an)防(fang)(fang)工(gong)(gong)程安(an)(an)裝公司時一定需要(yao)貨比三家，仔細研究(jiu)效(xiao)果(guo)和方案的好壞再決議，萬不(bu)可只看品(pin)牌(pai)了事。當然(ran)(ran)，好品(pin)牌(pai)自然(ran)(ran)也(ye)(ye)不(bu)容(rong)易作假，安(an)(an)防(fang)(fang)設備的質量也(ye)(ye)是很有(you)保障的。
