攝像(xiang)頭監控系統黑屏

攝像頭監(jian)(jian)控系(xi)統(tong)黑屏指視頻監(jian)(jian)控系(xi)統(tong)部(bu)分(fen)或(huo)者全部(bu)無畫面顯示的(de)情況。導致監(jian)(jian)控系(xi)統(tong)畫面黑屏的(de)原因有很多種，一般都采用排(pai)除法排(pai)查。

• 攝像頭(tou)IP變動，無法連接主機導致黑屏

這種(zhong)情況一(yi)般(ban)家用(yong)(yong)(yong)或小(xiao)型(xing)監(jian)控(kong)系統(tong)中比較(jiao)常(chang)見。家用(yong)(yong)(yong)或小(xiao)型(xing)監(jian)控(kong)系統(tong)大(da)多(duo)采用(yong)(yong)(yong)共用(yong)(yong)(yong)網絡(luo)的形式，再加上使用(yong)(yong)(yong)家用(yong)(yong)(yong)型(xing)的傳(chuan)輸設(she)備，例(li)如，家用(yong)(yong)(yong)型(xing)路(lu)由器等。對視頻監(jian)控(kong)系統(tong)的傳(chuan)輸造成(cheng)一(yi)定(ding)影響(xiang)。同時家用(yong)(yong)(yong)網絡(luo)使用(yong)(yong)(yong)過(guo)程中經常(chang)重(zhong)啟路(lu)由器，造成(cheng)IP變動，也(ye)是攝像頭監(jian)控(kong)系統(tong)黑(hei)屏的原因之一(yi)。

l  解決(jue)辦法：

1.     采(cai)用(yong)固定IP的(de)形(xing)式。同(tong)時打(da)開路由器UPNP。

2.     使用更穩定的企業級路由器。

• 電(dian)源問題

攝(she)像(xiang)(xiang)頭(tou)(tou)(tou)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)出(chu)現(xian)問題也會(hui)導致(zhi)攝(she)像(xiang)(xiang)頭(tou)(tou)(tou)監(jian)控(kong)系統(tong)(tong)無畫(hua)面。監(jian)控(kong)系統(tong)(tong)一般(ban)有三種供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)方式：POE供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)、單(dan)(dan)獨供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)和(he)集(ji)(ji)中供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)。POE供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)是通過網線將視頻(pin)監(jian)控(kong)系統(tong)(tong)電(dian)(dian)(dian)(dian)(dian)源和(he)信號統(tong)(tong)一傳輸(shu)的一種方式。單(dan)(dan)獨供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)指每個(ge)(ge)攝(she)像(xiang)(xiang)頭(tou)(tou)(tou)有單(dan)(dan)獨的變壓(ya)(ya)器，直接將220V的電(dian)(dian)(dian)(dian)(dian)源轉換為攝(she)像(xiang)(xiang)頭(tou)(tou)(tou)可以(yi)使用的電(dian)(dian)(dian)(dian)(dian)源。集(ji)(ji)中供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)系統(tong)(tong)采用一個(ge)(ge)變壓(ya)(ya)器將交流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)轉換為直流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)之后，再為每個(ge)(ge)攝(she)像(xiang)(xiang)頭(tou)(tou)(tou)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)。單(dan)(dan)獨供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)更為穩(wen)定，一般(ban)不(bu)(bu)會(hui)出(chu)現(xian)電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)和(he)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)不(bu)(bu)穩(wen)的情況。而集(ji)(ji)中供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)容易(yi)造成電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)不(bu)(bu)穩(wen)，導致(zhi)攝(she)像(xiang)(xiang)頭(tou)(tou)(tou)供(gong)(gong)(gong)(gong)電(dian)(dian)(dian)(dian)(dian)不(bu)(bu)足出(chu)現(xian)黑(hei)屏。

排查方法(fa)：

1.     檢(jian)查(cha)故障攝像頭的電(dian)源(yuan)輸入(ru)，電(dian)源(yuan)、電(dian)流(liu)是否正常(chang)。

2.    ; 檢查(cha)整個視頻監控系統供(gong)電(dian)(dian)輸(shu)出電(dian)(dian)壓、電(dian)(dian)流是否(fou)穩定(ding)。

• 網線或者(zhe)光(guang)纖斷路，造成監控信號(hao)無法傳(chuan)輸

線(xian)路斷路也是造(zao)(zao)成(cheng)監(jian)控(kong)系(xi)統黑(hei)(hei)屏的原因之一。視頻監(jian)控(kong)系(xi)統傳輸線(xian)路一般情(qing)況下采用光纖和(he)網線(xian)。無論采用上述哪種線(xian)路，都應做好保護措施。比(bi)如(ru)，采用PVC管(guan)或者線(xian)槽(cao)等。否(fou)則很容易被(bei)(bei)風化，甚(shen)至被(bei)(bei)老鼠咬斷線(xian)。造(zao)(zao)成(cheng)監(jian)控(kong)系(xi)統黑(hei)(hei)屏。

排查辦法：

1.     人工排(pai)查(cha)(cha)(cha)，單個攝像(xiang)頭(tou)黑屏，檢查(cha)(cha)(cha)該(gai)攝像(xiang)頭(tou)的(de)傳輸(shu)線路。整(zheng)個監(jian)(jian)控系統無畫面，排(pai)查(cha)(cha)(cha)監(jian)(jian)控系統主(zhu)傳輸(shu)線路。網線水晶頭(tou)，光纖焊(han)接(jie)接(jie)口(kou)也是容易損壞的(de)地方，應重點(dian)排(pai)查(cha)(cha)(cha)。

2.     測線儀排(pai)查。測線儀在視頻監控工程項目中應用(yong)比較(jiao)多。比人工排(pai)查要簡單的多，只(zhi)需要將設備接到網線的兩頭，設備會自動排(pai)查線路是否故障。

如果以上都(dou)排查完，故障還是沒有解(jie)決的(de)話(hua)，不排除(chu)是監控攝像頭(tou)損壞(huai)造(zao)成的(de)。可以將攝像頭(tou)取下，到售后維(wei)修(xiu)(xiu)點去檢測(ce)維(wei)修(xiu)(xiu)。

以上就是關于監控系統攝(she)像頭黑(hei)屏產生(sheng)的原(yuan)因及一些排查(cha)方法的介紹，若(ruo)有不足之處，歡迎(ying)大家(jia)互相(xiang)探討。
