校園安全監控系統(tong) 的應用及功能

    完整的天地(di)偉業校園(yuan)安(an)防系統由矩陣(zhen)、DVR、網(wang)絡一體球(qiu)、智(zhi)能終端、逆向解碼、報警、IC卡及廣播八個部分組成。各部分可(ke)靈活搭配(pei)，充分適應校園(yuan)安(an)防的需要。 

    校(xiao)(xiao)(xiao)(xiao)(xiao)(xiao)園(yuan)安防系(xi)統(tong)(tong)，以校(xiao)(xiao)(xiao)(xiao)(xiao)(xiao)園(yuan)網(wang)為(wei)核心(xin)，可(ke)充分利用(yong)(yong)已有(you)(you)線路，或根據布線的難易，在學校(xiao)(xiao)(xiao)(xiao)(xiao)(xiao)內(nei)(nei)同(tong)時(shi)采用(yong)(yong)不同(tong)的設(she)(she)(she)備，設(she)(she)(she)立多個子(zi)(zi)系(xi)統(tong)(tong)。如某棟樓(lou)內(nei)(nei)建設(she)(she)(she)矩(ju)陣或DVR子(zi)(zi)系(xi)統(tong)(tong)，將(jiang)樓(lou)內(nei)(nei)各監(jian)(jian)(jian)控(kong)(kong)點的音視頻(pin)及控(kong)(kong)制線集(ji)中(zhong)到(dao)分控(kong)(kong)中(zhong)心(xin)，在分控(kong)(kong)中(zhong)心(xin)將(jiang)各種信(xin)號統(tong)(tong)一(yi)接(jie)(jie)入(ru)校(xiao)(xiao)(xiao)(xiao)(xiao)(xiao)園(yuan)網(wang)。在具有(you)(you)信(xin)息(xi)點的監(jian)(jian)(jian)控(kong)(kong)位置，直(zhi)接(jie)(jie)采用(yong)(yong)網(wang)絡一(yi)體球(qiu)將(jiang)音頻(pin)和(he)視頻(pin)圖像經網(wang)絡一(yi)體球(qiu)實時(shi)壓(ya)縮(suo)編(bian)碼后，通過(guo)校(xiao)(xiao)(xiao)(xiao)(xiao)(xiao)園(yuan)網(wang)可(ke)以將(jiang)監(jian)(jian)(jian)控(kong)(kong)信(xin)號接(jie)(jie)入(ru)本(ben)樓(lou)或附近的二級監(jian)(jian)(jian)控(kong)(kong)中(zhong)心(xin)，或直(zhi)接(jie)(jie)上傳(chuan)到(dao)主(zhu)控(kong)(kong)室。在教室內(nei)(nei)可(ke)選(xuan)擇智能終端作為(wei)監(jian)(jian)(jian)控(kong)(kong)設(she)(she)(she)備，在將(jiang)監(jian)(jian)(jian)控(kong)(kong)信(xin)號上傳(chuan)到(dao)校(xiao)(xiao)(xiao)(xiao)(xiao)(xiao)園(yuan)網(wang)的同(tong)時(shi),還可(ke)以進(jin)行VOD點播(bo)等(deng)(deng)應(ying)用(yong)(yong)。各種設(she)(she)(she)備均為(wei)天地(di)偉(wei)業自主(zhu)研(yan)發，采用(yong)(yong)目前國際上最先進(jin)的MPEG4及H.263壓(ya)縮(suo)編(bian)碼技術，互相(xiang)兼容(rong)，同(tong)時(shi)視頻(pin)傳(chuan)輸對(dui)網(wang)絡帶寬的要求不是很(hen)高，可(ke)解決(jue)網(wang)絡帶寬等(deng)(deng)問題。

 ;   該系(xi)統(tong)在(zai)總(zong)(zong)控室設有(you)組(zu)合式(shi)電視墻上述(shu)設備(bei)均可連接到配置(zhi)在(zai)總(zong)(zong)控室的(de)逆向解(jie)碼主機(ji)的(de)視頻輸出端(duan)。支持虛擬(ni)矩(ju)陣功能，可實現前(qian)端(duan)所(suo)有(you)視頻到電視墻的(de)切換(huan)，方便用(yong)戶(hu)使用(yong)。總(zong)(zong)控室還可以(yi)配置(zhi)多臺(tai)系(xi)統(tong)服務器(qi)，用(yong)于整個監控系(xi)統(tong)的(de)設備(bei)管理(li)、用(yong)戶(hu)管理(li)、控制管理(li)、錄像管理(li)等。當學校不希望采用(yong)電視墻時，可采用(yong)PC解(jie)碼，用(yong)投(tou)影機(ji)或顯(xian)示器(qi)進行(xing)集(ji)中監控。

    該系統的(de)報(bao)警(jing)(jing)部(bu)分不(bu)是孤立的(de)目前視(shi)(shi)頻(pin)(pin)監控系統正處在從以(yi)DVR為核心的(de)結構，向以(yi)分布式、網絡化、智(zhi)能化、分散的(de)以(yi)每(mei)個視(shi)(shi)頻(pin)(pin)點為基礎的(de)轉變(bian)過程中。報(bao)警(jing)(jing)系統正在從一(yi)個單獨的(de)系統或視(shi)(shi)頻(pin)(pin)系統輔(fu)助部(bu)分，向和(he)視(shi)(shi)頻(pin)(pin)系統一(yi)起作為安防系統中兩個重要的(de)組成(cheng)部(bu)分，并融(rong)合(he)為一(yi)個統一(yi)整(zheng)體的(de)方向發展，并且(qie)逐漸成(cheng)為安防系統新的(de)設計標準。

    目前，校園安防(fang)系統可(ke)分為兩大(da)部分：
