style="text-indent:25px">安防監(jiān)控電源好壞選購時(shí)考慮的幾個(gè)要素：1.用途明確，有的放矢電源和安防設(shè)備是配套存在，不同電源輸出功率都不同，工作狀況也不一樣，在選購電源時(shí)，只有針對(duì)自己所使用的范圍有明確的了解，才能選購出正確的電源產(chǎn)品。2.防雨，防浪，防雷擊，散熱功能這一點(diǎn)主要針對(duì)室外監(jiān)控電源而言。大雨，強(qiáng)雷，暴曬——室外充滿各種不可控的氣候因素，而要保證365天不間斷運(yùn)作，電源產(chǎn)品必須有面對(duì)各種情景的應(yīng)變和防護(hù)能力。其中散熱功能與之相對(duì)的是外殼的耐高溫功能，一般外殼耐高溫要達(dá)到60°，現(xiàn)在市場較高是65°。3.品牌電源，質(zhì)量保證品牌是一個(gè)產(chǎn)品的臉面。撐得起一個(gè)面子的品牌，必然是歷史悠久，信譽(yù)度高，能夠長期為客戶提供品質(zhì)產(chǎn)品和服務(wù)的企業(yè)。因此，選購電源產(chǎn)品時(shí)，較好選擇品質(zhì)好，信譽(yù)有保證的企業(yè)購買。如深圳市小耳朵電源有限公司，XED電源品牌已經(jīng)深入人心，現(xiàn)場也有相應(yīng)的電源測試儀，對(duì)于電源產(chǎn)品的質(zhì)量，各類參數(shù)，都可以進(jìn)行當(dāng)場測試。</p><p style="text-indent:25px">自立RVV線供電：根據(jù)終端攝像機(jī)的功率大小，一般的固定機(jī)功率不超過10W，紅外機(jī)一般不超過20W，球機(jī)約為35W。單純從功率上來說，RVV2*0.5的線就足夠了，國標(biāo)0.5的線可以帶約1KW的負(fù)載。遠(yuǎn)距離，考慮到衰減，建議采用不小于1.0的線。如果攝像機(jī)的數(shù)量較少(5臺(tái)以內(nèi))且攝像機(jī)與監(jiān)控主機(jī)的間隔較近(少于50米)，每臺(tái)攝像機(jī)可獨(dú)自布RVV2×0.5電源線到監(jiān)控室并用小型變壓器供電。如果攝像機(jī)的數(shù)量較多，則應(yīng)采納大功率的12V直流穩(wěn)壓電源集中供電。在工過程中，要考慮到悉數(shù)攝像機(jī)的總功率和由傳輸線路所形成的電壓降(稱說“線損”，規(guī)格為1m2的銅導(dǎo)線每100m的電阻是1.8Ω)。對(duì)于一幢樓的監(jiān)控，施工時(shí)一般用2條2.5-6m2的銅芯雙塑線作為電源主線由監(jiān)控室引至線井，并沿線井走至各攝像機(jī)樓層的線井。對(duì)樓層各攝像機(jī)的供電，可由該層線井引1條RVV2×1或RVV2×1.5(若該層的攝像機(jī)數(shù)量超越6臺(tái))電源線給攝像機(jī)供電，或用RVV2×0.5護(hù)套線一一引線對(duì)應(yīng)供電。拋錨停擺，整系統(tǒng)癱瘓，造成無可挽回的損失。</p><div
