style="text-indent:25px">近幾年來，國內防爆攝像機業(yè)幾乎每年都在以兩位數(shù)的增長率快速發(fā)展，2016年防爆攝像機業(yè)總產值突破5400億元，預計2020年將達到萬億規(guī)模。市場不斷擴大，需求不斷增強。按道理，整個行業(yè)應該更加欣欣向榮，眾多防爆攝像機企業(yè)應該活的更加滋潤。然而事實卻并非如此，從2014年開始，一股防爆攝像機業(yè)倒閉潮就開始在業(yè)界蔓延，尤其是深圳沿海一些中小防爆攝像機企業(yè)，更有多家企業(yè)倒閉。防爆攝像機產品生命周期一般分為起步、成長、成熟和衰退共四個階段，早期的防爆攝像機產品屬于起步、發(fā)展階段，因此單體利潤較高，而且市場需求又大，可以養(yǎng)活更多的中小企業(yè)。但在進入成熟期后，產品便出現(xiàn)同質化現(xiàn)象，進而會進入衰退期。有實力的企業(yè)便會應用較新的技術，推出更較高的替代產品，而實力較差的企業(yè)則由于技術差異化競爭力較弱，則會被市場淘汰出局?，F(xiàn)實就是如此殘酷，內蒙古國產防爆紅外攝像頭，你不投入開發(fā)，就要落后，內蒙古國產防爆紅外攝像頭。而這也是近來防爆攝像機業(yè)技術差異化競爭愈演愈烈的根源所在，內蒙古國產防爆紅外攝像頭。防爆紅外攝像機畫面不清晰的原因：電流衰減速度快，可能導致紅外燈沒能正常工作。內蒙古國產防爆紅外攝像頭</p><div

style="text-indent:25px">防爆攝像機解析度技術分析：從某種程度上來說，防爆攝像機的像素、線數(shù)和清晰度這幾個參數(shù)與大家經常使用的電腦顯示器、電視機、手機顯示屏的相關參數(shù)是一樣的，三者都是對防爆攝像機畫面質感的描述，這樣有利于從多種角度了解把握防爆攝像機的畫面質感，這也是很多人無法弄清它們之間關系的一個原因。防爆攝像機的像素，它是組成圖像的基本元素，防爆攝像機的監(jiān)控畫面是由連續(xù)快速出現(xiàn)的圖像組成的，而這些圖像都是由一個一個像素點組成。就相當于把一副圖像放大很多倍之后，再將它從左到右從上到下有規(guī)則的分成很多個格子，在每一個格子內填充一個顏色，再把圖像縮小為原來的大小，這樣就組成了一副我們平時看到的圖像。而這些格子就相當于像素點，像素點數(shù)量的多少一般由廠家視情況而定。像素點越多，圖像就越細膩越清晰，也就是分辨率越高。</p><p style="text-indent:25px">防爆攝像機日常維護具體事項：1、對長時間工作的防爆監(jiān)控設備每月定期維護一次。如硬盤錄像機長時間工作會產生較多的熱量，一旦其電風扇有故障影響散熱，應盡快更換，以免硬盤錄像機工作不正常。2、對容易老化的防爆監(jiān)控設備部件每月一次進行較全檢查，一旦發(fā)現(xiàn)老化現(xiàn)象應及時更換、維修，如防爆攝像頭等。3、對易吸塵部份每季度定期清理一次。如防爆監(jiān)視器暴露在空氣中，由于屏幕的靜電作用，會有許多灰塵被吸附在防爆監(jiān)視器表面，影響畫面的清晰度，要定期擦拭防爆監(jiān)視器，校對防爆監(jiān)視器的顏色及亮度。4、對防爆監(jiān)控系統(tǒng)及設備的運行情況進行監(jiān)控，分析運行情況，及時發(fā)現(xiàn)并排除故障。如：網(wǎng)絡設備、服務器系統(tǒng)、監(jiān)控終端及各種終端外設。桌面系統(tǒng)的運行檢查，網(wǎng)絡及桌面系統(tǒng)的病毒防御。當達不到使用環(huán)境可能釋放物質的級別、溫度組別，或類別不對時，應視為非防爆電氣設備。</p><div

style="text-indent:25px">防爆攝像機監(jiān)控系統(tǒng)的常見故障及排除：1、監(jiān)視器上畫面上產生若干條細條紋的干擾。這種干擾現(xiàn)象的產生，多數(shù)是因為在傳輸系統(tǒng)、系統(tǒng)前端或中心控制室附近有較強的、頻率較高的空間輻射源。解決辦法：在系統(tǒng)建立時，應對周邊環(huán)意有所了解，盡量設法避開或遠離輻射源:另一個辦法是當無法避開輻射源時，對前端及中心設備加強屏蔽，對傳輸線和管路采用鋼管并良好接地。2、圖像清晰度不高、細節(jié)部分丟失、嚴重時會出現(xiàn)彩色信號丟失或色飽和度過小。這是由于圖像信號的高頻端損失過大，以3MHz以上頻率的信號基本丟失造成的。這種情況或因傳輸距離過遠，而中間又無放大補償裝置;或因視頻傳輸電纜分布電容過大;或因傳輸環(huán)節(jié)中在傳輸線的芯線與屏蔽線間出現(xiàn)了集中分布的等效電容造成的。防爆攝像頭的防護：前端設備的防雷。淄博高清防爆攝像機廠家推薦</p><p style="text-indent:25px">監(jiān)控端的避雷措施應慎重，要考慮各種可能類型的雷擊入侵、對地環(huán)路電位差現(xiàn)象及電力供應突波等保護措施。內蒙古國產防爆紅外攝像頭</p><p style="text-indent:25px">防爆攝像機監(jiān)控系統(tǒng)的常見故障及排除：設備或部件本身的質量問題。從理論上說，各種設備和部件都有可能發(fā)生質量問題。但從經驗上看，純屬產品本身的質量問題，多發(fā)生在解碼器、電動云臺、傳輸部件等設備上。值得指出的是，某些設備從整體上講質量上可能沒有出現(xiàn)不能使用的問題，但從某些技術指標上卻達不到產品說明書上給出的指標。因此必須對所選的產品進行必要的抽樣檢測。如確屬產品質量問題，較好的辦法是更換該產品，而不應自行拆卸修理。內蒙古國產防爆紅外攝像頭</p></p><br
