class="title">詳細(xì)說明</p><div id="pv7rzfl" class="box"><p><p style="text-indent:25px">視頻門禁電源選擇的重要毫無疑問，電源是保障整個視頻門禁系統(tǒng)穩(wěn)定運行的基礎(chǔ)，對于電源選擇的好壞可以直接決定到工程商在實施此項目的時候是否能賺取到盡可能多的利潤，同時從電源的選擇上面也可以反映出工程商本身對于工程質(zhì)量的把控能力。很遺憾，筆者在調(diào)研整個視頻門禁的宏觀市場的時候發(fā)現(xiàn)，90%以上的系統(tǒng)故障是因為電源的選擇不當(dāng)引起的，有些故障可能已經(jīng)影響到了該項目的順利推廣。綜合看來，因為電源而引發(fā)的故障主要表現(xiàn)在如下幾個方面： ① 使用一段時間后，出現(xiàn)供電不足的故障現(xiàn)象。 ② 雷雨天之后，出現(xiàn)規(guī)模性電源故障。 ③ 天氣炎熱和寒冷出現(xiàn)電源故障。 ④ 蓄電池經(jīng)常壞，上海消防40v電源采購，也沒有起到斷電維持系統(tǒng)正常運行的能力。 ⑤ 線路短路導(dǎo)致電源被燒壞。 ⑥ 用電高峰期，上海消防40v電源采購，出現(xiàn)電源供電不足問題，上海消防40v電源采購。蓄電池經(jīng)常壞，也沒有起到斷電維持系統(tǒng)正常運行的能力。上海消防40v電源采購</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="上海消防40v電源采購,安防" src="https://tyunfile.71360.com/UploadFile/baoyixinneng/637441725407109475/5481036.png"></div><p style="text-indent:25px">監(jiān)控攝像機電源功率配置的技術(shù)問題：在監(jiān)控攝像機電源的配置方面，也要注意一些細(xì)節(jié)，比如不能整個監(jiān)控系統(tǒng)共用一個電源，因為系統(tǒng)維修的時候，經(jīng)常需要打開、關(guān)閉電源。所有的監(jiān)控攝像機在打開電源瞬間同時啟動，啟動電流特別大，對電源的沖擊力很大，嚴(yán)重的會燒毀電源。另外一個原因就是所有的監(jiān)控攝像機共用一臺電源，當(dāng)電源發(fā)生故障時，整個閉路監(jiān)控系統(tǒng)陷入癱瘓。正確的辦法可以通過一個例子來說明，如一個商務(wù)樓有100臺固定監(jiān)控攝像機，總共需要約800W的電源，如需采用PoE供電，正確的配置應(yīng)該是選擇4臺、每臺200W的PoE交換機，這種要求豐潤達(dá)16口系列和24口系列PoE交換機都滿足。這樣，當(dāng)某一臺交換機發(fā)生故障，可以把重要出入口的攝像機接到其它好的交換機上，不至于影響整個系統(tǒng)的工作。北京安防電源多少錢在攝像機出現(xiàn)故障的時候，可以迅速就出現(xiàn)故障的攝像機進(jìn)行故障排查。</p><div

style="text-indent:25px">如何配置安防監(jiān)控系統(tǒng)中UPS電源：UPS是伴隨計算機的誕生而出現(xiàn)后備電源。在安防監(jiān)控系統(tǒng)中越來越多應(yīng)用計算機技術(shù)，因此對電力供電質(zhì)量提出越來越高的要求。UPS不但可較全改善供電質(zhì)量，對整個系統(tǒng)乃至網(wǎng)絡(luò)數(shù)據(jù)較全保護(hù)，還可保證市電斷電和被人為破壞的特殊情況下，繼續(xù)正常工作運轉(zhuǎn)。由于安防監(jiān)控系統(tǒng)對供電要求較高，所以一般會選擇在線式(正弦波，市電要求)UPS電源。給安防監(jiān)控系統(tǒng)配備UPS電源時，首先應(yīng)估算整個系統(tǒng)設(shè)備的用電功率，安全系數(shù)一般取1.2-1.5為宜，為供電系統(tǒng)留有充分的冗余量。其次根據(jù)系統(tǒng)要求延時供電時間，計算配置電池組。較后，還應(yīng)注意使用環(huán)境，防潮通風(fēng)，注重降溫，延長平均無故障工作時間，提高系統(tǒng)的可靠性。UPS電源應(yīng)設(shè)置在監(jiān)控室，實行統(tǒng)一管理。當(dāng)市電不正常時能及時為系統(tǒng)設(shè)備提供不間斷電力供應(yīng)，確保系統(tǒng)工作正常。</p><p style="text-indent:25px">選擇智能門禁電源時應(yīng)該注意什么：視頻門禁報警系統(tǒng)簡介視頻門禁項目伴隨著社會管理創(chuàng)新的進(jìn)步，對于人口尤其是流動人口的管理起到不可替代的作用，目前全國各地對于視頻門禁的建設(shè)都在如火如荼的進(jìn)行，已經(jīng)在安防行業(yè)中形成了一種新的市場力量。為了適應(yīng)市場的需求，目前無論是門禁系統(tǒng)的供應(yīng)商、還是視頻系統(tǒng)的供應(yīng)商，包括配套的光端機、電源等等的供應(yīng)商都在根據(jù)視頻門禁市場的特定需求在優(yōu)化自己的產(chǎn)品方案以使自己的能在市場競爭中能更具有競爭力。本文主要是針對視頻門禁應(yīng)用場合的特點，結(jié)合自己的實際視頻門禁工程經(jīng)驗，分享在實際的項目選型中，對于視頻門禁電源的選擇應(yīng)該注意的幾個問題。采用交流24V，在調(diào)試攝像機的時候，可以選擇電源同步。</p><div

style="text-indent:25px">下面來列舉幾項安防監(jiān)控電源的注意事項：1，功率虛標(biāo)這是較常見的現(xiàn)象。目前市場上不少標(biāo)注2A的安防監(jiān)控電源，其實際輸出只有1A左右甚至更低！部分安防監(jiān)控電源因為采用了劣質(zhì)元器件或拆機件等不合格元器件，在使用一段時間后，輸出功率發(fā)生明顯衰減！對攝像機的影響：攝像機的圖像產(chǎn)生抖動、無彩色或無圖像，夜視效果不佳。嚴(yán)重的，甚至無法啟動攝像機（尤其是晚上紅外燈開啟的時候）。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，采用過載過溫保護(hù)設(shè)計，甚至省掉保險管。不良影響：導(dǎo)致攝像機被燒毀，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。所有的攝像機在打開電源瞬間同時啟動，啟動電流特別大，對電源的沖擊力很大，嚴(yán)重的會燒毀電源。北京安防電源多少錢</p><p style="text-indent:25px">如果是在室內(nèi)，可以用好點的帶護(hù)套電源線。上海消防40v電源采購</p><p style="text-indent:25px">關(guān)于開關(guān)電源和線性電源的選擇：在實際的項目運用中到底是選擇開關(guān)電源還是選擇線性電源，很多工程商朋友都無從下手，其實只要把握兩點就可以了：①在南方炎熱地區(qū)的項目，如果選擇線性電源，建議不要將線性電源和其他設(shè)備放在同一個設(shè)備箱中，因為線性電源損耗大，本身發(fā)熱很厲害，和其他設(shè)備在一個設(shè)備箱中，如果散熱不及時很有可能會引起其他設(shè)備的運行不穩(wěn)定。而如果線性電源配套**的箱體的話，會帶來一些成本上的增加。②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。上海消防40v電源采購</p></p><br
