1．紅外探頭對人的橫向移動敏感度較高，而對縱向移動的敏感度稍低，所以安裝時較好將探頭的朝向與人的行走的方向垂直。 2．室內(nèi)紅外探頭不允許安裝在戶外，否則容易發(fā)生誤報。 3．避免面對窗外、空調(diào)、火爐、陽光等溫度會發(fā)生快速變化的地方及空氣流速較高的地方，以避免誤報。 4．使用未標(biāo)明有防寵物功能的紅外探頭，在布防時請將寵物關(guān)在探頭監(jiān)測不到的地方。 5．探測范圍內(nèi)不應(yīng)有大型阻擋物。氯甲烷報警器報警器通過較為先進(jìn)的空氣壓力檢測技術(shù)，來真正的實(shí)現(xiàn)免安裝。</p><div style="width:100%;text-align: center;"><img
