一、 環境准備
官網下載海康的Web端視頻插件以及開發的Demo、文檔
進入運行管理平台獲取到 Appkey、AppSecret、Ip、Port
二、 引入文件
在index.html中引入插件文件
引入插件
三、 代碼實現
批量預覽list的數據格式如下
list = [ { cameraIndexCode: "", ezvizDirect: 0, gpuMode: 0, streamMode: 0, transMode: 1, wndId: 1 // 預覽的窗口 }, { cameraIndexCode: "", ezvizDirect: 0, gpuMode: 0, streamMode: 0, transMode: 1, wndId: 2 } ]
