攝(she)像頭安防監控系(xi)統拓撲圖
大家都知道攝像頭安防監控系統是由前端監控攝像頭、傳輸設備、控制存儲設備、顯示設備構成。但是這些設備是如何達到我們想要的功能呢?今天我們就來說說攝像頭安防監控系統的拓撲圖,也叫示意圖。
小(xiao)型攝像頭安防(fang)監(jian)控系統拓撲(pu)圖
我們先(xian)看(kan)一個比(bi)較簡單的(de)(de)攝(she)像頭(tou)安(an)(an)防(fang)(fang)(fang)監(jian)控(kong)(kong)系(xi)統拓撲圖,這個也(ye)是大家(jia)平常接觸最(zui)多的(de)(de)。適(shi)用于家(jia)庭安(an)(an)防(fang)(fang)(fang)監(jian)控(kong)(kong)系(xi)統,小型超市監(jian)控(kong)(kong)系(xi)統。其主要(yao)設(she)備由監(jian)控(kong)(kong)攝(she)像頭(tou)、交(jiao)換(huan)機(ji)、NVR硬盤(pan)(pan)錄像機(ji)、顯示器構(gou)成。監(jian)控(kong)(kong)攝(she)像頭(tou)負責采集前端圖像數據,交(jiao)換(huan)機(ji)將音視頻信號傳輸到(dao)NVR硬盤(pan)(pan)錄像機(ji),最(zui)后經由顯示器展示出前端的(de)(de)畫面,這就是攝(she)像頭(tou)安(an)(an)防(fang)(fang)(fang)監(jian)控(kong)(kong)系(xi)統的(de)(de)工(gong)作原(yuan)理。

如(ru)果單單從大型攝(she)像(xiang)(xiang)頭安防監(jian)控(kong)系(xi)統(tong)(tong)的原理(li)圖上(shang)看(kan)(kan),其實(shi)(shi)它(ta)與(yu)小型監(jian)控(kong)系(xi)統(tong)(tong)的差距并(bing)不是(shi)(shi)(shi)(shi)很大,只是(shi)(shi)(shi)(shi)多了一(yi)(yi)個(ge)數字(zi)矩陣(zhen)、電(dian)視(shi)(shi)(shi)墻(qiang)、管(guan)(guan)理(li)服(fu)務器(qi)和IPSAN。但是(shi)(shi)(shi)(shi)實(shi)(shi)際施工過程中(zhong)比小型監(jian)控(kong)系(xi)統(tong)(tong)的要求更(geng)高,組網更(geng)復(fu)雜(za)。那么大型攝(she)像(xiang)(xiang)頭安防監(jian)控(kong)系(xi)統(tong)(tong)中(zhong)數字(zi)矩陣(zhen)和電(dian)視(shi)(shi)(shi)墻(qiang)可以(yi)(yi)看(kan)(kan)做(zuo)是(shi)(shi)(shi)(shi)一(yi)(yi)套顯示設(she)(she)備,他(ta)們兩個(ge)是(shi)(shi)(shi)(shi)相互依存(cun)的。意思是(shi)(shi)(shi)(shi)若(ruo)要使用(yong)電(dian)視(shi)(shi)(shi)墻(qiang),就必(bi)須(xu)要有(you)視(shi)(shi)(shi)頻(pin)矩陣(zhen)。管(guan)(guan)理(li)服(fu)務器(qi)是(shi)(shi)(shi)(shi)對(dui)整(zheng)個(ge)安防監(jian)控(kong)系(xi)統(tong)(tong)的控(kong)制工具(ju),可以(yi)(yi)對(dui)單個(ge)攝(she)像(xiang)(xiang)頭進行設(she)(she)置(zhi)更(geng)改(gai),也可以(yi)(yi)對(dui)整(zheng)個(ge)監(jian)控(kong)系(xi)統(tong)(tong)進行各種設(she)(she)置(zhi)。IPSAN是(shi)(shi)(shi)(shi)存(cun)儲(chu)服(fu)務器(qi),負(fu)責存(cun)儲(chu)視(shi)(shi)(shi)頻(pin)監(jian)控(kong)錄(lu)(lu)像(xiang)(xiang),它(ta)比硬盤錄(lu)(lu)像(xiang)(xiang)機更(geng)加穩定(ding),同時還(huan)可以(yi)(yi)設(she)(she)置(zhi)熱(re)備份功能(neng),防止監(jian)控(kong)錄(lu)(lu)像(xiang)(xiang)丟失。
大(da)(da)(da)(da)型(xing)安(an)(an)防(fang)監(jian)(jian)控(kong)(kong)系(xi)(xi)統與小(xiao)型(xing)安(an)(an)防(fang)監(jian)(jian)控(kong)(kong)系(xi)(xi)統在(zai)原(yuan)理圖(tu)上并沒有太(tai)大(da)(da)(da)(da)的(de)差異,但是在(zai)整個方案(an)設計和設備選擇,以及施(shi)工(gong)過程(cheng)是有著非常(chang)大(da)(da)(da)(da)的(de)差異的(de)。大(da)(da)(da)(da)型(xing)安(an)(an)防(fang)監(jian)(jian)控(kong)(kong)系(xi)(xi)統由于監(jian)(jian)控(kong)(kong)點位數量(liang)較多、安(an)(an)裝環境復雜、傳(chuan)輸(shu)距(ju)離較遠,不僅要(yao)(yao)(yao)考慮到(dao)線材(cai)在(zai)長距(ju)離傳(chuan)輸(shu)時(shi)(shi)的(de)信(xin)號衰減問題(ti),同時(shi)(shi)也要(yao)(yao)(yao)考慮到(dao)監(jian)(jian)控(kong)(kong)傳(chuan)輸(shu)帶寬的(de)問題(ti),也就是組網的(de)問題(ti)。另外(wai),在(zai)大(da)(da)(da)(da)型(xing)案(an)件監(jian)(jian)控(kong)(kong)系(xi)(xi)統施(shi)工(gong)過程(cheng)中,由于現場環境復雜,在(zai)施(shi)工(gong)過程(cheng)中還可以會涉及到(dao)破土施(shi)工(gong),如果是市(shi)政道路,那(nei)就還需要(yao)(yao)(yao)辦(ban)理相關的(de)手續。因此,大(da)(da)(da)(da)小(xiao)安(an)(an)防(fang)監(jian)(jian)控(kong)(kong)系(xi)(xi)統原(yuan)理圖(tu)看似和小(xiao)型(xing)安(an)(an)防(fang)監(jian)(jian)控(kong)(kong)系(xi)(xi)統原(yuan)理圖(tu)區別不大(da)(da)(da)(da),但實際(ji)遇到(dao)的(de)問題(ti)遠遠大(da)(da)(da)(da)于小(xiao)型(xing)安(an)(an)防(fang)監(jian)(jian)控(kong)(kong)系(xi)(xi)統。
