style="text-indent:25px">安防監(jiān)控電源幾中供電方式的選擇：自立供電模式什么是自立供電自立供電是指在每個攝像機(jī)前端安裝自立的安防監(jiān)控電源，此安防監(jiān)控電源只為一個攝像機(jī)提供電力供應(yīng)。自立供電的好1、檢修簡單，更換電源簡易因為每個攝像機(jī)都有自立的安防監(jiān)控電源，在攝像機(jī)出現(xiàn)故障的時候，可以迅速就出現(xiàn)故障的攝像機(jī)進(jìn)行故障排查。若檢查出因安防監(jiān)控電源引起的故障，*需對單個故障電源進(jìn)行修理貨更換。2、避免出現(xiàn)監(jiān)控系統(tǒng)癱瘓現(xiàn)象用UPS，將會導(dǎo)致整個監(jiān)控系統(tǒng)無法正常工作，陷入癱瘓狀態(tài)。而在自立供電模式下，因安防監(jiān)控電源的故障，而導(dǎo)致單個或數(shù)個攝像機(jī)無法工作，避免出現(xiàn)監(jiān)控系統(tǒng)癱瘓現(xiàn)象。自立供電的不足1、成本過高多個自立安防監(jiān)控電源的成本之和，一般要比同等功率輸出的集中電源要高。此成本，不將線纜成本計算在內(nèi)。2、遭遇外力破壞的幾率更高因為自立安防監(jiān)控電源往往與攝像機(jī)距離較近，若是在室外條件下，更容易遭受日曬雨淋、雷擊等外力破壞因素的影響。因此選擇戶外**的自立安防監(jiān)控電源，尤其要注重該自立安防監(jiān)控電源的防護(hù)性能。測量電源實際輸出功率視頻門禁報警系統(tǒng)中涉及到要供電的設(shè)備非常繁多。</p><div

style="text-indent:25px">監(jiān)控攝像機(jī)電源功率配置的技術(shù)問題：監(jiān)控攝像機(jī)一般都會表明DC12V/AC24V通用，因此，在現(xiàn)在比較的常用的PoE供電、集中供電和自立供電三種供電方式下，需要選擇AC 24V的監(jiān)控電源，因為同樣的傳輸距離，電壓越高，損耗越小。電壓高了，負(fù)載就能得到比較充足的電壓。電源選擇容易，但是并不是所有的電壓都是穩(wěn)定的，因此，如何合理配置整個監(jiān)控系統(tǒng)的監(jiān)控攝像機(jī)電源功率就成為了很多年輕沒有經(jīng)驗的工程師為難了，而很多方案在實施的時候都發(fā)現(xiàn)當(dāng)初設(shè)計的電源容量不夠，需要追加設(shè)備，造成和甲方扯皮現(xiàn)象。實際上，由于攝像機(jī)在啟動瞬間，啟動電流很大，再加上工程上遠(yuǎn)距離傳輸?shù)膿p耗，所以，監(jiān)控攝像機(jī)需要的電源，不是簡單地把所有攝像機(jī)的額定功率相加。低成本的線性電源一般不帶電池充放電管理功能，很容易引起蓄電池的損壞。上海安防智能電源批發(fā)哪家好</p><p

style="text-indent:25px">安防監(jiān)控電源的主要危害包括以下方面：1、濾波不干凈、對圖像干擾嚴(yán)重目前市場上價格低廉到不合理的安防監(jiān)控電源，其線路板基本都沒有共模電感或濾波器。這樣商才能降低成本，贏得利潤空間。對監(jiān)控效果的不良影響：監(jiān)控畫面出現(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。2、輸入線、輸出線不合格電源的輸入線、輸出線的線徑過細(xì)，甚至采用劣質(zhì)材料如鋼包鋁。不良影響：使用一段時間后輸出功率不足。線纜護(hù)套開裂，尤其在冬天。輸入輸出線纜發(fā)生斷裂。影響監(jiān)控攝像頭正常工作。上海安防智能電源批發(fā)哪家好</p></p><br
