class="title">詳細說明</p><div id="7tuwars" class="box"><p><p style="text-indent:25px">自立供電與集中供電如何選擇：需要配置的電源功率=攝像機的額定功率*1.3*1.3*1.3 （注：如果監(jiān)控距離特別長，需要適當加大電源功率，并且提高電源電壓）。網(wǎng)絡(luò)攝像機電源的配置，較忌諱什么？較忌諱的是：整個監(jiān)控系統(tǒng)共用一個電源。原因如下： 1) 系統(tǒng)維修的時候，經(jīng)常需要打開、關(guān)閉電源。所有的攝像機在打開電源瞬間同時啟動，成都安防集中供電電源采購，啟動電流特別大，對電源的沖擊力很大，嚴重的會燒毀電源， 2) 所有的攝像機共用一臺電源，當電源發(fā)生故障時，整個閉路監(jiān)控系統(tǒng)陷入癱瘓。尤其是一些重要出入口的圖像無法監(jiān)視，可能會造成不必要的麻煩。那么正確的做法應該是怎樣呢？如上面例子，一個商務樓有100臺固定攝像機，總共需要約800W的電源，正確的配置應該是選擇4臺，成都安防集中供電電源采購、每臺200W的電源。這樣，當某一臺電源發(fā)生故障，可以把重要出入口的攝像機接到其它好的電源上，成都安防集中供電電源采購，不至于影響整個系統(tǒng)的工作。如果監(jiān)控距離太遠，需要配置更高電壓的電源。成都安防集中供電電源采購</p><div

style="text-indent:25px">集中供電的缺點：1、前期配置復雜監(jiān)控攝像機在啟動瞬間需要很大的啟動電源，而且遠距離的電力輸送會產(chǎn)生損耗，因此集中供電的功率并非是所有監(jiān)控攝像機的功率相加。采取集中供電模式，需要工程師對整個監(jiān)控系統(tǒng)有詳盡了解，以便做出合理方案。（實際上，由于攝像機在啟動瞬間，啟動電流很大，再加上工程上遠距離傳輸?shù)膿p耗，所以，監(jiān)控攝像機需要的電源，不是簡單地把所有攝像機的額定功率相加。正確的做法是把整個監(jiān)控系統(tǒng)的攝像機的額定功率相加再乘以1.3倍，這個是攝像機實際需要的功率，然后再加上約30%的損耗；較后再加上30%的余量，作為將來擴容使用。） 2、存在出現(xiàn)監(jiān)控系統(tǒng)癱瘓現(xiàn)象的可能性沒有采用UPS電源的集中供電模式下的供電系統(tǒng)一旦出現(xiàn)問題，將會導致整個監(jiān)控系統(tǒng)無法正常工作，陷入癱瘓狀態(tài)。成都安防集中供電電源采購周圍環(huán)境的照度是否滿足攝像機紅外燈開啟的條件。</p><div

style="text-indent:25px">后備式和在線式UPS工作原理：1）后備式UPS（離線式UPS）在市電正常時由市電直接向設(shè)備供電，當市電斷開時由蓄電池逆變供電。其特點是：結(jié)構(gòu)簡單，體積小，成本低，但輸入電壓范圍窄，有切換時間，不適用于對電源質(zhì)量要求高的設(shè)備，通常用于個人計算機。2）在線互動式UPS在市電正常時，由市電經(jīng)整流器供直流電給逆變器工作，由逆變器直接向設(shè)備提供交流電，同時充電器給蓄電池充電，保持蓄電池滿容量。逆變器始終處于工作狀態(tài)，保證不間斷輸出，不存在切換時間。適用于對電力質(zhì)量要求高的設(shè)備。</p><p style="text-indent:25px">寬幅電源與普通電源的區(qū)別：一、電壓輸出范圍不同。1、寬幅電源：寬幅電源電壓輸出范圍一般是在85～265VAC的標準。2、普通電源：普通電源電壓輸出范圍一般是在180V-240V的標準。二、對于電源的適應能力不同1、寬幅電源：寬幅電源對于電源的適應能力相對較強，適合那些電源電壓不穩(wěn)定的地方。2、普通電源：普通電源對于電源的適應能力相對較弱，適合那些電源電壓穩(wěn)定的地方。三、缺點不同1、寬幅電源：電器運行時，電器的寬幅電源會產(chǎn)生電磁干擾，如果嚴重還會產(chǎn)生噪音。2、普通電源：一旦電器的普通電源無法適應電壓寬幅，就會造成電器的自動斷電關(guān)機，嚴重的甚至會直接燒壞電器硬件。檢修簡單，更換電源簡易因為每個攝像機都有自立的安防監(jiān)控電源。</p><div

style="text-indent:25px">監(jiān)控攝像機電源的選擇還需要注意什么問題：：開始：在集中供電方案中給攝像機接電源時，不要把距離較遠的攝像機和距離較近的監(jiān)控攝像機接在同一臺電源上。如果接在同一臺電源上，電源電壓高了，會燒毀近距離的攝像機，電源電壓低了，距離較遠的攝像機無圖像。立方體攝相機采用寬電源設(shè)計，可以在直流輸入電壓12V—36V范圍內(nèi)長期穩(wěn)定工作，徹底根除輸入電壓不穩(wěn)定(如浪涌等)對攝像機造成的危害.可以很好地解決這個問題。是對攝像機集中供電的較佳解決方案。第二：如果監(jiān)控距離太遠，需要配置更高電壓的電源，如30V，36V等等，甚至直接供220V交流電，到前端再變壓。避免出現(xiàn)監(jiān)控系統(tǒng)癱瘓現(xiàn)象用UPS，將會導致整個監(jiān)控系統(tǒng)無法正常工作，陷入癱瘓狀態(tài)。上海安防寬溫電源哪家好</p><p style="text-indent:25px">請選擇AC24V的電源，因為同樣的傳輸距離，電壓越高，損耗越小，線的成本也越小。成都安防集中供電電源采購</p><p style="text-indent:25px">如何配置安防監(jiān)控系統(tǒng)的UPS電源：UPS電源是為安防監(jiān)控系統(tǒng)提供動力的中心部分，是為安防監(jiān)控系統(tǒng)提供持續(xù)、穩(wěn)定、不間斷電力供應的重要外部設(shè)備。目前，市場上供應的UPS電源設(shè)備種類繁多，輸出功率也有所不同。UPS電源按工作模式可分為后備式、在線式兩大類。按其輸出波形又分為方波輸出和正弦波輸出兩種。以下主要介紹了UPS電源的工作原理，以及如何配置安防監(jiān)控系統(tǒng)的UPS電源。備用電源是安防監(jiān)控系統(tǒng)基本要素之一。缺少備用電源的系統(tǒng)則暗藏致命缺陷，不能投入實際應用當中，因為極可能在關(guān)鍵時刻貽誤戰(zhàn)機，拋錨停擺，整系統(tǒng)癱瘓，造成無可挽回的損失。成都安防集中供電電源采購</p></p><br
