安防監控設備安裝工程屬于安防弱電工程項目,近幾年,隨著科技的進步,安防監控系統的更新發展速度明顯加快。不少高科技融入到了安防領域,例如:人臉識別門禁、AI人形分析監控系統等等。安防監控系統開始步入智能化的時代。
安防監控系統的發展史
最早的(de)(de)(de)(de)(de)(de)安(an)防(fang)監(jian)(jian)(jian)控(kong)(kong)(kong)系(xi)(xi)(xi)統(tong)全部使用的(de)(de)(de)(de)(de)(de)是(shi)模擬監(jian)(jian)(jian)控(kong)(kong)(kong)攝(she)像(xiang)(xiang)頭,也稱閉(bi)路視(shi)頻(pin)監(jian)(jian)(jian)控(kong)(kong)(kong)系(xi)(xi)(xi)統(tong)(CCTV)。閉(bi)路視(shi)頻(pin)監(jian)(jian)(jian)控(kong)(kong)(kong)系(xi)(xi)(xi)統(tong)屬于(yu)第一代安(an)防(fang)監(jian)(jian)(jian)控(kong)(kong)(kong)系(xi)(xi)(xi)統(tong),19世紀70年代左(zuo)右在(zai)我國(guo)開(kai)始(shi)出現(xian)。其由于(yu)當初(chu)的(de)(de)(de)(de)(de)(de)技術能(neng)力有限(xian),只能(neng)實(shi)現(xian)局(ju)域(yu)網內觀(guan)看。當時(shi)一套(tao)安(an)防(fang)監(jian)(jian)(jian)控(kong)(kong)(kong)系(xi)(xi)(xi)統(tong)構成比現(xian)在(zai)的(de)(de)(de)(de)(de)(de)視(shi)頻(pin)監(jian)(jian)(jian)控(kong)(kong)(kong)系(xi)(xi)(xi)統(tong)要復雜的(de)(de)(de)(de)(de)(de)多,涉及到(dao)主要的(de)(de)(de)(de)(de)(de)設備有:視(shi)頻(pin)畫(hua)面(mian)(mian)分(fen)割(ge)器(qi)、矩(ju)陣(zhen)、切換器(qi)、卡帶式錄(lu)像(xiang)(xiang)機(ji)(VCR)及視(shi)頻(pin)監(jian)(jian)(jian)視(shi)器(qi)等。CCTV監(jian)(jian)(jian)控(kong)(kong)(kong)系(xi)(xi)(xi)統(tong)有很大的(de)(de)(de)(de)(de)(de)局(ju)限(xian)性,由于(yu)當時(shi)傳(chuan)輸視(shi)頻(pin)監(jian)(jian)(jian)控(kong)(kong)(kong)信號(hao)的(de)(de)(de)(de)(de)(de)線(xian)路采(cai)用的(de)(de)(de)(de)(de)(de)是(shi)模擬視(shi)頻(pin)線(xian)纜,在(zai)傳(chuan)輸距離方面(mian)(mian)局(ju)限(xian)性很大,超過(guo)一定的(de)(de)(de)(de)(de)(de)距離之(zhi)后(hou),信號(hao)衰減嚴重(zhong),造(zao)成監(jian)(jian)(jian)控(kong)(kong)(kong)畫(hua)面(mian)(mian)不穩定。同時(shi)當時(shi)的(de)(de)(de)(de)(de)(de)CCTV監(jian)(jian)(jian)控(kong)(kong)(kong)受到(dao)各種硬件的(de)(de)(de)(de)(de)(de)影響擴展性能(neng)很差。比如,畫(hua)面(mian)(mian)分(fen)割(ge)器(qi)、矩(ju)陣(zhen)、切換器(qi)等等。當時(shi)的(de)(de)(de)(de)(de)(de)錄(lu)像(xiang)(xiang)保(bao)存是(shi)采(cai)用卡帶式錄(lu)像(xiang)(xiang)機(ji)VCR。一盤卡帶存儲(chu)滿之(zhi)后(hou),需要手(shou)動取出,放入新的(de)(de)(de)(de)(de)(de)空白卡帶。并且卡帶一旦消磁(ci)會造(zao)成錄(lu)像(xiang)(xiang)文件的(de)(de)(de)(de)(de)(de)丟失(shi)。
第(di)(di)二(er)代(dai)安(an)(an)防(fang)監(jian)控(kong)(kong)系(xi)(xi)統(tong)(tong)是(shi)(shi)(shi)“PC+多(duo)媒體(ti)卡”的(de)(de)(de)半數(shu)字安(an)(an)防(fang)監(jian)控(kong)(kong)系(xi)(xi)統(tong)(tong),是(shi)(shi)(shi)以(yi)數(shu)字硬盤(pan)錄(lu)(lu)(lu)像(xiang)(xiang)機DVR+模擬攝像(xiang)(xiang)機構(gou)成的(de)(de)(de)。其信號傳(chuan)(chuan)輸(shu)仍然使用視頻(pin)線纜進行傳(chuan)(chuan)輸(shu)。較(jiao)(jiao)第(di)(di)一代(dai)安(an)(an)防(fang)監(jian)控(kong)(kong)系(xi)(xi)統(tong)(tong),其存(cun)儲方(fang)(fang)案(an)進行優化,并(bing)且通過DVR可以(yi)進行錄(lu)(lu)(lu)像(xiang)(xiang)回放(fang)和實(shi)時(shi)預覽。但是(shi)(shi)(shi)由于當時(shi)DVR五花八(ba)門(men),沒(mei)有統(tong)(tong)一的(de)(de)(de)標準,因此第(di)(di)二(er)代(dai)安(an)(an)防(fang)監(jian)控(kong)(kong)系(xi)(xi)統(tong)(tong)并(bing)非(fei)是(shi)(shi)(shi)標準封閉的(de)(de)(de)安(an)(an)防(fang)監(jian)控(kong)(kong)系(xi)(xi)統(tong)(tong)。另外(wai)(wai),第(di)(di)二(er)代(dai)安(an)(an)防(fang)監(jian)控(kong)(kong)系(xi)(xi)統(tong)(tong)仍存(cun)在較(jiao)(jiao)大的(de)(de)(de)局限性(xing)(xing)。例如(ru):每個攝像(xiang)(xiang)機必(bi)須通過視頻(pin)線纜單獨(du)連接到DVR。同時(shi)擴展性(xing)(xing)方(fang)(fang)面(mian)只能達到16路的(de)(de)(de)監(jian)控(kong)(kong)點位。另外(wai)(wai),錄(lu)(lu)(lu)像(xiang)(xiang)存(cun)儲方(fang)(fang)面(mian),磁盤(pan)發生(sheng)故障風(feng)險與RAID冗余方(fang)(fang)面(mian),第(di)(di)二(er)代(dai)安(an)(an)防(fang)監(jian)控(kong)(kong)系(xi)(xi)統(tong)(tong)錄(lu)(lu)(lu)像(xiang)(xiang)方(fang)(fang)案(an)沒(mei)有保護,易丟(diu)失(shi)。
第三(san)代安(an)(an)防監控系統(tong)就是我們目前所一直沿用(yong)(yong)的(de)數字視頻監控系統(tong)。通過以(yi)太網實現全(quan)IP連接,并且用(yong)(yong)戶可以(yi)通過互聯(lian)網隨時(shi)隨地進行(xing)訪(fang)問。另外,基于無線(xian)網絡技術的(de)發展,無線(xian)監控攝(she)像(xiang)(xiang)頭安(an)(an)裝更(geng)加便捷。同時(shi),視頻清晰(xi)度方面也有了(le)跨越式(shi)的(de)變化。攝(she)像(xiang)(xiang)機管理(li)方面也可以(yi)通過互聯(lian)網對前端設備進行(xing)更(geng)改配置(zhi)。堅固冗余存儲器-可同時(shi)利用(yong)(yong)SCSI、RAID以(yi)及磁帶(dai)備份存儲技術永(yong)久保護監視圖(tu)像(xiang)(xiang)不受硬(ying)盤驅動(dong)器故障影響。
隨著科技(ji)(ji)(ji)的(de)進(jin)步(bu),推動了(le)安(an)防監(jian)(jian)控系統的(de)發(fa)展。目前基(ji)于AI人(ren)(ren)工智能技(ji)(ji)(ji)術而(er)(er)出現的(de)諸如(ru)人(ren)(ren)臉識別監(jian)(jian)控系統、AI人(ren)(ren)形分析監(jian)(jian)控系統等新型視頻監(jian)(jian)控系統,已經不(bu)再局限于看得(de)到(dao)、看得(de)清。而(er)(er)是可以(yi)通過不(bu)斷的(de)學習,讓(rang)機器學會“思考”,以(yi)模仿人(ren)(ren)類的(de)某些(xie)行為特征。相(xiang)信未(wei)來(lai)隨著科技(ji)(ji)(ji)的(de)進(jin)步(bu),安(an)防監(jian)(jian)控系統功能會越來(lai)越強大。
