style="text-indent:25px">防爆紅外攝像機畫面不清晰的原因：1、手工藝問題。很多手工安裝的時候，紅外燈不集中，散光了。分散的光線導(dǎo)致到處有光，一片灰蒙蒙的現(xiàn)象。紅外燈前端的棉花檔光不嚴密，因此一片蒼?，F(xiàn)象。2、紅外燈質(zhì)量差，紅外燈的角度及紅外距離跟鏡頭不匹配導(dǎo)致雪花飄。很多公司為了方便自己的采購及安裝，用多種角度不同的燈混合在一起使用，這樣使用的好處是他們同一種燈可以勉強使用不同毫米大小的鏡頭，壞處是總是讓人感覺燈的角度與距離與鏡頭不合適，當(dāng)角度不合適的時候，容易出現(xiàn)手電筒現(xiàn)象或者窄電現(xiàn)象。當(dāng)距離不匹配時，比如你用12MM的鏡頭，卻用十到二十米的燈，那么就會出現(xiàn)灰蒙蒙的現(xiàn)象，遠處一片模糊，近處雪花飄飄。還有，劣質(zhì)的紅外燈，除了裝飾外，燈越多，問題越多；燈越集中，發(fā)熱量越大，越容易燒壞。</p><p style="text-indent:25px">隔爆型防爆攝像機等于“隔爆攝像儀防護罩”+普通攝像機、鏡頭。這樣的話，只要尺寸合適，工程商就可以自由選擇內(nèi)置的攝像機、鏡頭，同時成本也降低了。對于以后的維護，也方便很多，斷電源即可開蓋取出攝像機、鏡頭。這樣的“隔爆攝像儀防護罩”通常以抗危險壓力和沖擊的大強度不銹鋼制成，極其堅固。質(zhì)量好的產(chǎn)品壁厚在5MM以上，比防彈級別的防暴攝像機有過之而無不及。很多情況下，不銹鋼外殼遠比鋁制外殼優(yōu)越，比如抗腐蝕性能。特別是火災(zāi)情況下的生存能力要遠遠好的多。防爆攝像頭的防護：應(yīng)雷的防護基本做法是對設(shè)備輸入輸出口設(shè)置“限壓保護電路”。</p><div

style="text-indent:25px">防爆攝像機如何防水防霧：攝像機小雨刷與隱形雨刷玻璃。監(jiān)控攝像機內(nèi)部應(yīng)具有自動除霜功能，攝像機在0℃時啟動加熱裝置除霜;在高溫天氣，恒溫裝置可以解決高溫度對敏感元器件，當(dāng)溫度高于50℃時，會自動啟動風(fēng)扇進行排風(fēng)降溫。外部溫度過低，自然會引起鏡頭出現(xiàn)水霧的情況，那么下面的方法就要靈驗了。監(jiān)控攝像機的構(gòu)造十分緊密，在北方的監(jiān)控攝像機很容易出現(xiàn)鏡頭起霧的現(xiàn)象，特別是內(nèi)外溫差過大，且內(nèi)部熱量無法快速排出時，一旦出現(xiàn)鏡頭起霧監(jiān)控的意義也就不復(fù)存在。為了解決這樣的問題，在監(jiān)控攝像機外面增加雨刷器或許能夠解決問題。防爆監(jiān)控攝像機使用：助燃氣體和不屬于甲類的氧化劑。安康微型防爆紅外攝像頭廠家</p><p style="text-indent:25px">霧、霜的形成是由于空氣中的飽和水蒸氣遇冷凝結(jié)而成，因冷環(huán)境的強、弱分別凝結(jié)成霜和霧。青島化工廠防爆攝像頭生產(chǎn)廠家</p><p style="text-indent:25px">防爆攝像機在什么檔次呢？攝像機較低照度。較低照度是當(dāng)被攝景物的光亮度低到一定程度而使防爆攝像機輸出的視頻信號電平低到某一規(guī)定值時的景物光亮度值。一般彩色防爆攝像機的較低照度為2～3LUX，照度的測定是以在一定的鏡頭光圈系數(shù)為前提，因此，不能只看防爆攝像機說明書中標明的較低照度，應(yīng)按防爆攝像機在同一光圈系數(shù)下其照度值的大小。較低照度越小，防爆攝像機檔次越高。相對于彩色攝像機而言，黑白攝像機由于沒有色度處理而只對光線的強弱（亮度）信號敏感，所以黑白防爆攝像機的照度比彩色防爆攝像機照度要低，一般可做到0.1LUX在F1.4時。青島化工廠防爆攝像頭生產(chǎn)廠家</p></p><br
