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。合肥安防智能電源多少錢避免出現(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)。</p><div

style="text-indent:25px">有效的防雷保護：因視頻門禁報警系統(tǒng)項目的特殊性，安裝環(huán)境惡劣(農(nóng)民房、出租房、老屋村、城中村)，室外線路交織，極易引雷，而且電源所連通的線路不可避免的要出現(xiàn)在室外，所以要求電源對于防雷應該要有極強的有效保護措施。產(chǎn)品是否有防雷保護的判斷：①目測電源上是否有保護電路的設計。(此方法適合對電路硬件有研究人士)。②了解廠家在防雷的技術上面是否有技術的積累，如產(chǎn)品可靠性的實際演示。相關產(chǎn)品的防雷檢測報告等等。筆者有了解過一個廠家為了證明產(chǎn)品的可靠性，可以現(xiàn)場模擬雷擊來直觀的展現(xiàn)產(chǎn)品的可靠性，這種方法值得推廣。雷雨天之后，出現(xiàn)規(guī)模性電源故障。</p><div

style="text-indent:25px">由于安防監(jiān)控系統(tǒng)對供電要求較高，所以必須選擇在線式(正弦波，市電要求)UPS電源。系統(tǒng)配備UPS電源時，首先應估算系統(tǒng)設備的用電功率，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，還應注意使用環(huán)境，防潮通風，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電源應設置在監(jiān)控室，實行統(tǒng)一管理。當市電不正常時，就能及時為系統(tǒng)的全部設備提供不間斷的電力供應，保證系統(tǒng)工作正常，防止人為破壞、保密、維修。安防監(jiān)控系統(tǒng)主要應用于各種商業(yè)樓宇、學校、醫(yī)院、校區(qū)、銀行、公路等等各個系統(tǒng)中間，而這些場所對公共民眾的重要性是很高的，所以在選擇配置其應急電源的過程中應該很慎重?？梢园阎匾鋈肟诘臄z像機接到其它好的電源上，不至于影響整個系統(tǒng)的工作。合肥安防智能電源多少錢</p><p

style="text-indent:25px">開關電源和普通的電源有什么區(qū)別：普通的電源一般是線性電源,線性電源，是指調(diào)整管工作在線性狀態(tài)下的電源.而在開關電源中則不一樣，開關管（在開關電源中，我們一般把調(diào)整管叫做開關管）是工作在開、關兩種狀態(tài)下的：開——電阻很??；關——電阻很大。開關電源是一種比較新型的電源。它具有效率高，重量輕，可升、降壓，輸出功率大等優(yōu)點。但是由于電路工作在開關狀態(tài)，所以噪聲比較大。通過下圖，我們來簡單的說說降壓型開關電源的工作原理。如圖所示，電路由開關K（實際電路中為三極管或者場效應管），續(xù)流二極管D，儲能電感L，濾波電容C等構成。當開關閉合時，電源通過開關K、電感L給負載供電，并將部分電能儲存在電感L以及電容C中。合肥安防電源批發(fā)價格</p></p><br
