style="text-indent:25px">下面來(lái)列舉幾項(xiàng)安防監(jiān)控電源的注意事項(xiàng)：外殼采用劣質(zhì)塑料電源外殼為電源重要保護(hù)，避免外力損壞電源或發(fā)生觸電事故。部分不良商家生產(chǎn)安防監(jiān)控所用的便宜劣質(zhì)塑料外殼，在使用較長(zhǎng)時(shí)間后或放在戶外環(huán)境使用，會(huì)發(fā)生變色、外殼開(kāi)裂現(xiàn)象。危害：假若電源進(jìn)水，輕則損壞電源，重則燒壞監(jiān)控?cái)z像頭，甚至發(fā)生觸電事故，傷及人身安全。選用劣質(zhì)電源，存在各種潛在的不必要風(fēng)險(xiǎn)故障。部分劣質(zhì)電源在前期使用并未出現(xiàn)明顯問(wèn)題，但在使用一段時(shí)期后容易出現(xiàn)各種故障，給監(jiān)控系統(tǒng)帶來(lái)以上所述的傷害，給選購(gòu)者帶來(lái)不必要的經(jīng)濟(jì)損失或聲譽(yù)損失。即使部分不良商家提供保修、包換服務(wù)，但其質(zhì)保服務(wù)對(duì)象很少于電源，對(duì)于劣質(zhì)電源所造成的附帶經(jīng)濟(jì)損失（如燒壞監(jiān)控?cái)z像頭等），則不承擔(dān)任何責(zé)任。因此，建議各位選購(gòu)安防監(jiān)控電源時(shí)，一定要擦亮眼睛，天津安防寬溫電源廠家，別被低價(jià)蒙騙，一定要看清選購(gòu)的安防監(jiān)控電源的電路設(shè)計(jì)。還有一般不良商家，給您承諾安防監(jiān)控電源長(zhǎng)期包換，但是很有可能給您帶來(lái)上述安防監(jiān)控電源以外的損失，天津安防寬溫電源廠家，天津安防寬溫電源廠家。比如：人工，設(shè)備等等。電路形式靈活多樣,選擇余地大。天津安防寬溫電源廠家</p><div

style="text-indent:25px">自立供電與集中供電如何選擇：自立供電與集中供電模式的優(yōu)缺點(diǎn)大致如上，具體怎么選擇，要視實(shí)際安裝環(huán)境及客戶要求而定。一般來(lái)說(shuō)，4路以下的監(jiān)控系統(tǒng)采用自立供電各為合適。 4路到16路的監(jiān)控系統(tǒng)，若距離相當(dāng)，建議選擇集中供電模式。 16路以上的監(jiān)控，可以采用多路集中供電結(jié)合，前提是必須做好前期配置。舉例子：如果一個(gè)商務(wù)樓，有100臺(tái)固定型網(wǎng)絡(luò)攝像機(jī)，每臺(tái)攝像機(jī)的額定功率是4W，我們?cè)撊绾闻渲脭z像機(jī)電源呢？根據(jù)上面的計(jì)算方法，我們計(jì)算出，攝像機(jī)的額定功率是4W*100臺(tái)=400W，攝像機(jī)實(shí)際使用的功率400W*1.3=520W。考慮損耗后，攝像機(jī)需要的功率是520W*1.3=676W 加上電源余量，攝像機(jī)較終需要配置的電源功率是676W*1.3=878W 。</p><p
