      隨著網(wǎng)絡(luò)的發(fā)展,基于IP技術(shù)的各種視頻通訊應(yīng)用也應(yīng)運而生(如網(wǎng)絡(luò)遠程視頻監(jiān)控),。其不但具傳統(tǒng)模擬視頻監(jiān)控的功能,,最重要的是具有網(wǎng)絡(luò)遠程視頻監(jiān)控,傳輸距離無界限,,監(jiān)控方便,;監(jiān)控畫面切換簡便快捷;圖像影象存取簡便容易;安裝簡易,,大大降低了綜合成本,。

      但由于監(jiān)控中心和監(jiān)控網(wǎng)絡(luò)攝像機的通訊,需要監(jiān)控網(wǎng)絡(luò)攝像機一端處具有靜態(tài)公網(wǎng)IP,這樣才能讓遠程監(jiān)控中心可以通過IP地址直接找到監(jiān)控網(wǎng)絡(luò)攝像機,。而我國目前的靜態(tài)IP短缺和價格昂貴,,不可能給每個的網(wǎng)絡(luò)監(jiān)控端(監(jiān)控網(wǎng)絡(luò)攝像機)都配備一個靜態(tài)IP。最好的解決辦法當(dāng)然是能在廉價的動態(tài)IP上解決遠程視頻監(jiān)控尋址問題,。

      動態(tài)域名解析解決方案
      動態(tài)域名解析是指將擁有動態(tài)IP的主機通過一個域名和其邦定,,遠端通過廣域網(wǎng)訪問該主機時直接通過訪問這個域名就可以了,而無須關(guān)心動態(tài)IP地址的變化,。
      動態(tài)域名解析系統(tǒng)一般由兩部分構(gòu)成,。第一部分是服務(wù)器端程序,位于服務(wù)商的主機上,。另一部分是客戶端程序,,就運行在廣大用戶的主機上。在每次連接網(wǎng)絡(luò)的時候,,客戶端程序就會通過信息傳遞,,把該主機的動態(tài)IP地址傳送給位于服務(wù)商主機上的服務(wù)器程序,服務(wù)器程序負(fù)責(zé)提供DNS服務(wù)并實現(xiàn)動態(tài)域名解析服務(wù),,再收到客戶端通知后服務(wù)器端程序立即更新數(shù)據(jù),,將新的IP地址和原有的固定域名綁定,這樣就完成了動態(tài)域名解析的服務(wù),。別人也就可以通過域名訪問你的服務(wù)器了,。

      動態(tài)IP遠程視頻監(jiān)控方案描述
      給每個監(jiān)控網(wǎng)絡(luò)攝像機申請一個域名(如:abc.88ip.cn),由域名解析系統(tǒng)來探查監(jiān)控網(wǎng)絡(luò)攝像機當(dāng)前的IP地址,,當(dāng)IP地址變化后,,88ip客戶端通知88ip域名解析系統(tǒng)服務(wù)器端及時刷新為新的IP地址并通知遠程視頻監(jiān)控端。遠程視頻監(jiān)控端通過固定不變的域名(如:abc.88ip.cn)來訪問每個監(jiān)控設(shè)備,,這樣再無需關(guān)心IP地址的變化于否,,動態(tài)IP轉(zhuǎn)化為“靜態(tài)”IP了。

      動態(tài)IP遠程視頻監(jiān)控方案的具體實施方式有以下幾種,。
      a) 路由器外掛
      具體的說路由器外掛就是采用集成88IP的路由器,,通過申請88IP域名和服務(wù),把申請所得用戶名密碼填入路由器DDNS" title="DDNS" target="_blank">DDNS" title="DDNS">DDNS" title="DDNS">DDNS" title="DDNS">DDNS" title="DDNS">DDNS" title="DDNS">DDNS"

      b) 采用集成88IP的網(wǎng)絡(luò)攝像機
      對于無人值守或不方便外掛路由器的狀況下,,遠程視頻監(jiān)控也可采用集成88Ip的網(wǎng)絡(luò)攝像機,同樣把申請88Ip服務(wù)得到的用戶名密碼填入相關(guān)項,,通過一條ADSL等寬帶線路直接相連,。遠程視頻監(jiān)控端通過域名直接訪問,。

      c) 運行88IP客戶端
      在局域網(wǎng)內(nèi)部的任一PC或服務(wù)器上運行88Ip客戶端,此時域名解析到的IP地址是局域網(wǎng)網(wǎng)關(guān)出口處的公網(wǎng)IP地址,,再在網(wǎng)關(guān)處作端口映射指向監(jiān)控設(shè)備即可,。

      動態(tài)IP遠程視頻監(jiān)控方案特點
      應(yīng)用靈活:可采用88IP,實現(xiàn)多種方式動態(tài)IP尋址,。
      連網(wǎng)費用低:不用花費高額的費用申請帶固定IP的DDN專線,,廉價的寬帶線路即可。
      支持多種連網(wǎng)方式:88ip系統(tǒng)可支持ISDN,、xDSL,、Cable Modem、小區(qū)寬頻網(wǎng)絡(luò)等各種分配公網(wǎng)IP的互聯(lián)網(wǎng)接入線路,。
      操作方便,、快速:不需每次連網(wǎng)時打電話或使用即時通訊軟件向?qū)Ψ皆儐朓P地址,只需在監(jiān)控軟件中輸入全球唯一的域名即,,使用時感覺不到88Ip的存在,。
      適用范圍廣:只要在能上網(wǎng)的地方,全球均可對它進行授權(quán)訪問,。并可很容易的支持不同廠家的各種網(wǎng)絡(luò)監(jiān)控設(shè)備,,包括網(wǎng)絡(luò)攝像機,網(wǎng)絡(luò)視頻服務(wù)器,,門禁控制器,,可視電話等。
