隨著網絡的發(fā)展，基于IP技術的各種視頻通訊應用也應運而生(如網絡遠程視頻監(jiān)控)。其不但具傳統(tǒng)模擬視頻監(jiān)控的功能，最重要的是具有網絡遠程視頻監(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)控網絡攝像機的通訊，需要監(jiān)控網絡攝像機一端處具有靜態(tài)公網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)控網絡攝像機。而我國目前的靜態(tài)IP短缺和價格昂貴，不可能給每個的網絡監(jiān)控端(監(jiān)控網絡攝像機)都配備一個靜態(tài)IP。最好的解決辦法當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，遠端通過廣域網訪問該主機時直接通過訪問這個域名就可以了，而無須關心動態(tài)IP地址的變化。
動態(tài)域名解析系統(tǒng)一般由兩部分構成。第一部分是服務器端程序，位于服務商的主機上。另一部分是客戶端程序，就運行在廣大用戶的主機上。在每次連接網絡的時候，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商主機上的服務器程序，服務器程序負責提供DNS服務并實現(xiàn)動態(tài)域名解析服務，再收到客戶端通知后服務器端程序立即更新數(shù)據，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。別人也就可以通過域名訪問你的服務器了。
動態(tài)IP遠程視頻監(jiān)控方案描述
給每個監(jiān)控網絡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)控網絡攝像機當前的IP地址，當IP地址變化后，88ip客戶端通知88ip域名解析系統(tǒng)服務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)控設備，這樣再無需關心IP地址的變化于否，動態(tài)IP轉化為“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，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的網絡攝像機
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的網絡攝像機，同樣把申請88Ip服務得到的用戶名密碼填入相關項，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
在局域網內部的任一PC或服務器上運行88Ip客戶端，此時域名解析到的IP地址是局域網網關出口處的公網IP地址，再在網關處作端口映射指向監(jiān)控設備即可。
動態(tài)IP遠程視頻監(jiān)控方案特點
應用靈活：可采用88IP，實現(xiàn)多種方式動態(tài)IP尋址。
連網費用低：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。
支持多種連網方式：88ip系統(tǒng)可支持ISDN、xDSL、Cable Modem、小區(qū)寬頻網絡等各種分配公網IP的互聯(lián)網接入線路。
操作方便、快速：不需每次連網時打電話或使用即時通訊軟件向對方詢問IP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：只要在能上網的地方，全球均可對它進行授權訪問。并可很容易的支持不同廠家的各種網絡監(jiān)控設備，包括網絡攝像機，網絡視頻服務器，門禁控制器，可視電話等。
