style="text-indent:25px">防爆攝像機(jī)的夜視效果黑白圖像更好？夜視彩色圖像的意義？對于一張普通夜視監(jiān)控圖像來說，彩色與黑白又有哪些意義呢？在考慮圖像清晰度的前提下，夜視黑白圖像成像更好；考慮到存儲(chǔ)容量，夜視黑白顯然更省空間；考慮到監(jiān)控距離，顯然黑白更占優(yōu)勢…如果這些都不是你所追求的，那么恐怕你的需求你定符合下面的應(yīng)用。夜視監(jiān)控彩色成像需補(bǔ)光。在沒有額外光線的前提下，夜視監(jiān)控大多采用黑白模式，其對比效果十分明顯。但是夜視監(jiān)控抓拍圖像又不全為黑白圖像，因特殊要求，東營微型防爆攝像頭生產(chǎn)廠家，采用及時(shí)補(bǔ)光設(shè)備，也可以在夜晚實(shí)現(xiàn)彩色抓拍。以道路監(jiān)控為例，由于車牌底色分藍(lán)、黃、黑、白等不同顏色，如果全采用黑白成像一定會(huì)出現(xiàn)嚴(yán)重的誤差。每個(gè)路口負(fù)責(zé)抓拍違章的監(jiān)控的攝像機(jī)都必須配有補(bǔ)光燈，白色LED補(bǔ)光提供足夠的光源，而為了保證光線平衡，監(jiān)控?cái)z像機(jī)兩邊各有一塊補(bǔ)光燈。其實(shí)，彩色圖像不一定全能，東營微型防爆攝像頭生產(chǎn)廠家，夜視黑白依然能夠解決實(shí)際應(yīng)用問題。在沒有特殊要求的前提下，在低照度的環(huán)境中，無論采用紅外燈還是感光元器件，所傳達(dá)的意義是相同的。按需所分配才是較佳解決方案，東營微型防爆攝像頭生產(chǎn)廠家。在火災(zāi)環(huán)境臨時(shí)用電作業(yè)，同樣也存在人身觸電等安全問題。東營微型防爆攝像頭生產(chǎn)廠家</p><div

style="text-indent:25px">不銹鋼防爆攝像機(jī)護(hù)罩的耐腐性比碳鋼好。不銹鋼按組織狀態(tài)分為：馬氏體鋼、鐵素體鋼、奧氏體鋼、奧氏體-鐵素體（雙相）不銹鋼及沉淀硬化不銹鋼等。其中沉淀硬化型不銹鋼是通過熱處理手段使鋼中碳化物沉淀析出，從而提高的鋼強(qiáng)度，具有很好的成形性能和良好的焊接性，可作為超大強(qiáng)度的材料在核工業(yè)、航空和航天工業(yè)中應(yīng)用。不銹鋼防爆攝像機(jī)護(hù)罩主要采用304不銹鋼材質(zhì)，產(chǎn)品表面可應(yīng)客戶需求選擇原面加工（不銹鋼原色）或高溫噴涂氟碳烤漆的防銹處理。由于不銹鋼防爆攝像機(jī)護(hù)罩對碳含量的要求高于碳鋼，因而工藝更為復(fù)雜，以及它們所含其他成分的差異，成本上碳鋼防爆攝像機(jī)護(hù)罩優(yōu)于不銹鋼；從不銹鋼和碳鋼的防腐蝕性來說，不銹鋼防爆攝像機(jī)護(hù)罩更勝一籌，并且同種產(chǎn)品，不銹鋼產(chǎn)品更輕。因此，在相對優(yōu)勢和劣勢并存的情況下，企業(yè)應(yīng)該根據(jù)自身的需求來選擇合適材質(zhì)的產(chǎn)品。咸陽戶外防爆攝像機(jī)廠家防爆攝像機(jī)設(shè)備維護(hù)注意事項(xiàng)：防雷、防干擾。</p><div

style="text-indent:25px">防爆攝像機(jī)的紅外燈選擇技巧：1、LED類紅外燈產(chǎn)品分為有紅爆和無紅爆兩類。（1）有紅爆產(chǎn)品使用波長為850nm的紅外led發(fā)射管，使用中，近距離觀察，紅外燈會(huì)發(fā)出暗紅色的光。（2）而無紅爆產(chǎn)品使用波長為940nm的紅外led發(fā)射管，使用中，紅外燈表面沒有任何光亮，因此更隱蔽。同一款防爆紅外攝像機(jī),在850nm波長的感應(yīng)度,比在940nm波長的感應(yīng)度好到10倍。所以850nm這種有輕微紅暴的紅外燈擁有更高的效率,應(yīng)當(dāng)做為紅外燈的選擇。2、激光管：介于這種紅外燈的特性，防爆紅外攝像機(jī)中用的較少，期特點(diǎn)是照射距離較遠(yuǎn)，但角度很小，如果角度調(diào)大以后，由于能量有限，所以距離相對而言又變短了。從而可以看出，激光管應(yīng)用于安防業(yè)是很矛盾的;</p><p
