對(duì)于需要將不同視頻協(xié)議做融合的項(xiàng)目，我們一般都是建議大家選用EasyCVR視頻平臺(tái)，EasyCVR支持多種協(xié)議的視頻接入，對(duì)于通用的第三方協(xié)議，我們支持了海康的Ehome和GB28181的國(guó)標(biāo)協(xié)議。

EasyCVR視頻網(wǎng)關(guān)平臺(tái)接入的部分Ehome設(shè)備顯示離線，可以從下圖中看到，除了通過(guò)HIKSDK接入的設(shè)備外，通過(guò)Ehome接入的設(shè)備全部離線：

可見(jiàn)離線的部分設(shè)備都是Ehome協(xié)議接入，Ehome設(shè)備為主動(dòng)注冊(cè)類型，判斷設(shè)備是否真實(shí)在線的方法一般為抓取對(duì)應(yīng)對(duì)端口7660的包，或者是在海康sdk的回調(diào)函數(shù)中添加打印日志（輸出對(duì)應(yīng)的設(shè)備信息ip，端口，ehomeid等），例如通過(guò)下圖中DevID 090223對(duì)應(yīng)企業(yè)的數(shù)據(jù)，可以確認(rèn)該企業(yè)在線。

同種方法過(guò)濾相關(guān)日志，查找對(duì)應(yīng)企業(yè)的Ehome id。日志中未有相關(guān)id信息。判斷這些企業(yè)真實(shí)離線。建議企業(yè)自查下海康NVR Ehome配置界面, 查看在線狀態(tài)或者是否啟用Ehome
