style="text-indent:25px">防爆攝像機：目前防爆攝像機的市場競爭非常激烈，雖然我們可以通過防爆等級和國家認證等級來認定某種防爆攝像機是否滿足自己的要求，但是有很多廠家經(jīng)常打著牌子的幌子，以次充好，拿著價格來誤導客戶，使很多工程商上當受騙。因此在這里，小編提醒各位有意購買防爆攝像機的客戶們要擦亮眼睛，驗證產(chǎn)品的等級合格證，多查看關于產(chǎn)品的評論，咸陽戶外防爆紅外攝像頭，看自身比較適合哪個等級的產(chǎn)品，一般來說，肯定是等級越高，防爆性能越好，價格也就越高。防爆攝像機解析度技術分析：說到防爆攝像機，衡量解析度的像素、線數(shù)和清晰度這幾個參數(shù)就不可避免的要涉及到。然而很多工程商們在購買防爆攝像機的時候對這三個參數(shù)根本就無法搞清楚，有的人甚至連它們的概念都不知道，咸陽戶外防爆紅外攝像頭。這也無可厚非，因為很多供應商在提供產(chǎn)品給工程商時，咸陽戶外防爆紅外攝像頭，大家由于時間的問題，再加上參數(shù)之間關系與產(chǎn)品交易并沒有多大影響，因此供應商和工程商一般只大概交涉像素的多少而已，而不會涉及到像素、線數(shù)和清晰度的關系問題。防爆攝像頭的防護：通常是將前端設備如防爆攝像頭置于接閃器(避雷針或其它接閃導體)有效保護范圍之內。咸陽戶外防爆紅外攝像頭</p><div

style="text-indent:25px">防爆攝像頭的防護：視頻監(jiān)控中心的防雷。在視頻監(jiān)控系統(tǒng)中，視頻監(jiān)控中心往往是處理視頻監(jiān)控錄像的地方，因此其防雷也顯得格外重要。簡單來說，視頻監(jiān)控中心防雷應從直擊雷防護、防雷電波侵入、對設備輸入輸出口設置“限壓保護電路”。從直擊雷防護來說，視頻監(jiān)控中心所在建筑物應有防直擊雷的避雷針、避雷帶或避雷網(wǎng)。架空電纜線直接引入時，在入戶處應加裝避雷器，并設置“限壓保護電路”。當然，如果電纜全程穿金屬管有困難，可在電纜進入終端和前端設備前穿金屬管埋地引入，但埋地長度不得小于15米，在入戶端將電纜金屬外皮、鋼管同防雷接地裝置相連。</p><p 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、紅外燈質量差，紅外燈的角度及紅外距離跟鏡頭不匹配導致雪花飄。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?？刂菩盘杺鬏斁€采用具有隔離遮蔽功能的纜線。</p><div

style="text-indent:25px">防爆攝像機在什么檔次呢？視頻信號的標稱值為1Vp-p，標準值為0.7Vp-p，較低照度時的視頻信號值為1/3到1/2的標準植。所以防爆攝像機在較低照度時的圖像，決不會“如同白晝一樣”。另外，防爆攝像機在較低照度時產(chǎn)生的圖像清晰度，是用電視信號測試卡進行測式的，其黑白相間的條紋，要求黑色反射率近于0%，白色反射率大于89.9%。而我們在現(xiàn)場觀察時有時不具備這樣的條件，比如：樹葉和草地的反射率很低，反差很小，就不易獲得清晰圖像。因此實際使用當中不能以防爆攝像機標稱的較低照度作為衡量現(xiàn)場環(huán)境照度的標準。工作電流過大將影響其壽命，甚至使紅外二極管燒毀。濟南防爆紅外攝像頭哪家好</p><p style="text-indent:25px">為了將雷電流從信號傳輸線傳導入地，電纜都應該加裝突波保護器。咸陽戶外防爆紅外攝像頭</p><p style="text-indent:25px">防爆攝像頭有特定的使用環(huán)境：防爆攝像頭一般不用于民用監(jiān)控系統(tǒng)，民用監(jiān)控系統(tǒng)一般的監(jiān)控攝像機就可以滿足其需求，民用可以不用安裝防爆性能的攝像機，防爆攝像頭一般用于環(huán)境比較特殊的產(chǎn)所，現(xiàn)在全國如：石油、化工、礦井、**、醫(yī)藥、油庫、輪船、鉆井平臺、加油站、花炮生產(chǎn)、糧食加工儲存等普遍應用。這個特定的環(huán)境很大一部分限制了防爆攝像頭的普遍推廣，在短期內，防爆攝像頭還是無法在普通產(chǎn)所大量應用，需要一個大眾逐漸接受的過程，相信隨著民眾安防意識的不斷提高，防爆攝像頭在不久的將來肯定可以大放異彩，走進千家萬戶。咸陽戶外防爆紅外攝像頭</p></p><br
