攝像頭通電了，電源指示燈也亮了(指示燈亮不**就能正常工作)，通電2分鐘了無法觀看監(jiān)控，復位也沒反應，可以將攝像頭斷電，拔出內(nèi)存卡，然后通電，如果問題依舊，可以找個電源盒子替換一下以方便鑒別問題。例如，寬帶貓，或電視機頂盒，或路由器的電源都是和監(jiān)控相匹配的怎么知道是否能用呢?上述設備都有標簽紙，你看下有沒有寫12V，如果有寫可以用，外驅(qū)動電源廠家，相互交叉替換很快就知道問題所在了 </p> <p> 給電源適配器通電，電源指示燈常亮，**攝像頭內(nèi)部有短路，如果電源指示燈滅**電源燒壞。 </p> <p> <span style="display:none;"></span>電源適配器壞了怎么辦呢？ </p> <p> 如果是剛買的設備或在保修期內(nèi)，可以聯(lián)系商家在線客服說明情況，外驅(qū)動電源廠家，看看能不能給你補發(fā)，如果有條件可以就近購買，推薦購買12V3A的電源 </p> <p> 由于電源屬于高壓部件如果這邊供電不穩(wěn)定或經(jīng)常停電，配電箱沒做任何防漏電或防浪涌保護器或防雷模塊,或大功率設備較多的地方可能電源損壞的概率較高 </p> <p> <br />

電源適配器DC插頭也簡稱為DC頭，它是電源適配器連接與其供電的產(chǎn)品的一個連接器，它是音叉DC頭采取的由音叉型金屬接觸彈片或直插DC頭采取的金屬空心圓柱形接觸體，絕緣基座，橫向插口，縱向插口，定向鍵槽等組成。電源適配器DC 插頭的內(nèi)徑外徑規(guī)格有5.5*2.5、5.5*2.1、4.75 *1.7、4.0*1.7、3.5*1.35、3.5*1.1、3.2*0.9、3.0*1.1、2.5*0.7、2.35*0.7、2.0*0.6單位為MM等等。 </p> <p> <br /> </p> <p> 電源適配器DC頭有很多種類：例如我們常見的音叉DC**，直插DC**這兩種**為常見，還有用于通訊類和IT類產(chǎn)品的micro USB頭，mini USB頭，USB頭，以及不常見的有點煙器頭，F(xiàn)頭， T頭，DC直插母頭，航空頭，防水頭，3芯/4芯/5芯/8芯連接頭，鱷魚夾，音頻頭，S端子，冰箱頭，香蕉頭等等DC頭。 </p> <p> <br /> </p> <p> 電源適配器DC插頭連接方式為兩只叉型接觸彈片定位在基座中心部位（音叉式DC頭）或一個光滑的空心金屬圓柱體定位在基座中心部位（直插式DC頭）成縱橫向排列互不相連。外露在絕緣基座圓柱體外面的同樣為一個空心金屬圓柱體（音叉式和直插式DC頭外露金屬連接部分沒有差別），由此與插座內(nèi)外連接使其通電供給與其供電之產(chǎn)品導通并供電，使之正常工作。 </p> <p> <br />

筆記本電腦是一種高度集成化的用電設備，其對電壓和電流的要求很高。同時其內(nèi)部電子元器件也相對脆弱，如果輸入的電流或電壓不在相關電路的設計范圍內(nèi)，就可能造成燒毀芯片或其他電子元器件的嚴重后果，所以筆記本電腦供電設備的電源適配器和電池的穩(wěn)定性就變得十分重要。 </p> <p> 與筆記本電腦供電相關的故障很多，一方面是由于筆記本電腦主機內(nèi)保護隔離電路和充電控制電路等相關電路出現(xiàn)問題造成的，另一方面則是由于電源適配器和電池本身出現(xiàn)問題造成的。 </p> <p> 電源適配器常見故障主要包括無電壓輸出或輸出電壓不穩(wěn)等。筆記本電腦電源適配器的輸入電壓通常為交流電100V～240V，如果電源適配器的接入電壓不在這個區(qū)間內(nèi)，那么就很有可能造成電源適配器燒毀的故障。電源適配器自身的發(fā)熱量很大，如果在使用過程中散熱條件不好就可能導致內(nèi)部電路無法正常工作，從而造成無電壓輸出或電壓輸出不穩(wěn)的故障。 </p> <p> 由于筆記本電腦電池自身問題造成的故障主要包括電池無電壓輸出、無法充電等。筆記本電腦電池的電芯充電和放電都具有一定的限度，如果超過其限度就可能造成損壞。電池內(nèi)的電路板對充放電有一定的保護作用，但是其本身也有可能產(chǎn)生故障，從而造成電池出現(xiàn)無電壓輸出或無法充電的故障。 </p><div style="width:100%;text-align:
