style="text-indent:25px">下面來(lái)列舉幾項(xiàng)安防監(jiān)控電源的注意事項(xiàng)：1，功率虛標(biāo)這是較常見(jiàn)的現(xiàn)象。目前市場(chǎng)上不少標(biāo)注2A的安防監(jiān)控電源，其實(shí)際輸出只有1A左右甚至更低！部分安防監(jiān)控電源因?yàn)椴捎昧肆淤|(zhì)元器件或拆機(jī)件等不合格元器件，在使用一段時(shí)間后，輸出功率發(fā)生明顯衰減！對(duì)攝像機(jī)的影響：攝像機(jī)的圖像產(chǎn)生抖動(dòng)、無(wú)彩色或無(wú)圖像，夜視效果不佳。嚴(yán)重的，甚至無(wú)法啟動(dòng)攝像機(jī)（尤其是晚上紅外燈開(kāi)啟的時(shí)候）。2，保護(hù)措施不足不少劣質(zhì)安防監(jiān)控電源，未按正常電源設(shè)計(jì)，采用過(guò)載過(guò)溫保護(hù)設(shè)計(jì)，甚至省掉保險(xiǎn)管。不良影響：導(dǎo)致攝像機(jī)被燒毀，在極端情況電源本身出現(xiàn)冒煙現(xiàn)象甚至發(fā)生著火。3，濾波不干凈、對(duì)圖像干擾嚴(yán)重目前市場(chǎng)上價(jià)格低廉到不合理的安防監(jiān)控電源，其線路板基本都沒(méi)有共模電感或?yàn)V波器。這樣商才能降低成本，贏得利潤(rùn)空間。對(duì)監(jiān)控效果的不良影響：監(jiān)控畫(huà)面出現(xiàn)波紋干擾，在光線較差的環(huán)境下（如黑夜）波紋干擾尤為明顯。</p><p style="text-indent:25px">安防電源怎樣維修：安防電源怎樣維修安防電源其實(shí)跟監(jiān)控電源差不多的，都是用在監(jiān)控設(shè)備上面的。不過(guò)安防電源也是可以用在很多的電子產(chǎn)品上面的。安防電源的特點(diǎn)是體積小，重量輕，效率高等特點(diǎn)。一般的話人們在使用攝像機(jī)的時(shí)候一般的話都會(huì)選擇安防電源，也會(huì)選擇監(jiān)控電源因?yàn)檫@兩種電源都是差不多的。功率也是一樣的，沒(méi)有很大的差別。不過(guò)就是有的時(shí)候安防電源跟監(jiān)控電源有的區(qū) 別的。安防電源在維修的時(shí)候如果出現(xiàn)了安防電源不供電的時(shí)候可以插上電池試試以下，如果電子產(chǎn)品可以正常運(yùn)行就說(shuō)明是安防電源線或者是安防電源有問(wèn)題，可以先用表檢測(cè)然后在檢查安防電源線是不是有問(wèn)題，這樣的話可以減少安防電源的維修難度。如果電源線沒(méi)有問(wèn)題的話就需要把安防電源拆開(kāi)了。避免出現(xiàn)監(jiān)控系統(tǒng)癱瘓現(xiàn)象用UPS，將會(huì)導(dǎo)致整個(gè)監(jiān)控系統(tǒng)無(wú)法正常工作，陷入癱瘓狀態(tài)。</p><div

（注：如果監(jiān)控距離特別長(zhǎng)，需要適當(dāng)加大電源功率，并且提高電源電壓）。網(wǎng)絡(luò)攝像機(jī)電源的配置，較忌諱什么？較忌諱的是：整個(gè)監(jiān)控系統(tǒng)共用一個(gè)電源。原因如下： 1) 系統(tǒng)維修的時(shí)候，經(jīng)常需要打開(kāi)、關(guān)閉電源。所有的攝像機(jī)在打開(kāi)電源瞬間同時(shí)啟動(dòng)，啟動(dòng)電流特別大，對(duì)電源的沖擊力很大，嚴(yán)重的會(huì)燒毀電源， 2) 所有的攝像機(jī)共用一臺(tái)電源，當(dāng)電源發(fā)生故障時(shí)，整個(gè)閉路監(jiān)控系統(tǒng)陷入癱瘓。尤其是一些重要出入口的圖像無(wú)法監(jiān)視，可能會(huì)造成不必要的麻煩。那么正確的做法應(yīng)該是怎樣呢？如上面例子，一個(gè)商務(wù)樓有100臺(tái)固定攝像機(jī)，總共需要約800W的電源，正確的配置應(yīng)該是選擇4臺(tái)、每臺(tái)200W的電源。這樣，當(dāng)某一臺(tái)電源發(fā)生故障，可以把重要出入口的攝像機(jī)接到其它好的電源上，不至于影響整個(gè)系統(tǒng)的工作。濟(jì)南集中式安防電源廠家推薦</p></p><br
