style="text-indent:25px">防爆紅外攝像機(jī)應(yīng)用中的問題：防爆監(jiān)控中還有低照度與紅外能互補(bǔ)選擇，其實(shí)低照度防爆攝像機(jī)和防爆紅外攝像機(jī)屬于互補(bǔ)的產(chǎn)品，低照度防爆攝像機(jī)成本高、質(zhì)量高、無需輔助光的優(yōu)勢彌補(bǔ)防爆紅外攝像機(jī)的在某些場所夜視監(jiān)控場所的空白，但選擇時(shí)一定要注意廠家的資質(zhì)了，而防爆紅外攝像機(jī)則因?yàn)槌杀镜瓦@一優(yōu)勢占據(jù)了沒有特殊要求的防爆夜視監(jiān)控市場。用戶要合理選擇和利用，當(dāng)選擇低照度防爆攝像機(jī)，既然大家要去選用低照度防爆攝像機(jī)，這時(shí)，一定要關(guān)注它的后面的狀態(tài)，選定狀態(tài)之后更穩(wěn)妥的方式還是自己要安排一個(gè)暗室，自己比較這些相關(guān)產(chǎn)品，這樣會(huì)把市場上一些虛標(biāo)，或者不標(biāo)狀態(tài)可以分辨出來，然后對(duì)有些項(xiàng)目里面，對(duì)低照度防爆攝像機(jī)選用，還是在同等狀態(tài)下比較，這樣才可以達(dá)到相對(duì)科學(xué)的結(jié)果。希望大家要根據(jù)預(yù)算的情況選擇使用何種夜間監(jiān)控的防爆攝像機(jī)。防爆紅外攝像機(jī)不清晰解決：采用雙濾光片或者雙玻璃結(jié)構(gòu)，提高晚上紅外燈的攝入程度和避免水霧影響鏡頭。</p><div
