style="text-indent:25px">防爆攝像頭維護(hù)注意事項(xiàng)防雷、防干擾：只要從事過(guò)機(jī)電系統(tǒng)的維護(hù)工作的人都知道，雷雨天氣一來(lái)，防爆設(shè)備遭雷擊是常事，給防爆監(jiān)控設(shè)備正常的運(yùn)行造成很大的安全隱患，因此，防爆監(jiān)控設(shè)備在維護(hù)過(guò)程中必須對(duì)防雷問(wèn)題高度重視。防雷的措施主要是要做好設(shè)備接地的防雷地網(wǎng)，應(yīng)按等電位體方案做好**的地阻小于1歐的綜合接地網(wǎng)，杜絕弱電系統(tǒng)的防雷接地與電力防雷接地網(wǎng)混在一起的做法，以防止電力接地網(wǎng)雜波對(duì)設(shè)備產(chǎn)生干擾。防干擾則主要做到布線時(shí)應(yīng)堅(jiān)持強(qiáng)弱電分開(kāi)原則，把電力線纜跟通訊線纜和視頻線纜分開(kāi)，嚴(yán)格按通信和電力行業(yè)的布線規(guī)范施工。</p><p style="text-indent:25px">防爆攝像頭的防護(hù)：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(jiǎn)單來(lái)說(shuō)，視頻監(jiān)控中心防雷應(yīng)從直擊雷防護(hù)、防雷電波侵入、對(duì)設(shè)備輸入輸出口設(shè)置“限壓保護(hù)電路”。從直擊雷防護(hù)來(lái)說(shuō)，視頻監(jiān)控中心所在建筑物應(yīng)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(shí)，在入戶處應(yīng)加裝避雷器，并設(shè)置“限壓保護(hù)電路”。當(dāng)然，如果電纜全程穿金屬管有困難，可在電纜進(jìn)入終端和前端設(shè)備前穿金屬管埋地引入，但埋地長(zhǎng)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。防爆攝像機(jī)維護(hù)：硬盤錄像機(jī)長(zhǎng)時(shí)間工作會(huì)產(chǎn)生較多的熱量。</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(wú)紅爆兩類。（1）有紅爆產(chǎn)品使用波長(zhǎng)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(wú)紅爆產(chǎn)品使用波長(zhǎng)為940nm的紅外led發(fā)射管，使用中，紅外燈表面沒(méi)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(zhǎng)的感應(yīng)度,比在940nm波長(zhǎng)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(duì)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;監(jiān)控終端的各種金屬管線應(yīng)做管線接地處理并共同接到接地裝置上。青島紅外防爆紅外攝像機(jī)</p><p
