vue2和3 对接 海康摄像头插件 (视频WEB插件 V1.5.2)

前端 0

前言

海康视频插件v.1.5.2版本运行环境需要安装插件VideoWebPlugin.exe,对浏览器也有兼容性要求,具体看官方文档

功能

1. 摄像头的预览与停止预览

2. 窗口布局设置

3. 页面多次调用组件唯一性

4. 初始单个预览与多个预览

5. 组件窗口自适应

6. 双击窗口全屏

对应下载插件

去海康官网下载插件 里面有dome等其他需要用到的

地址:

安装插件

打开下载的文件里的bin文件 安装一下VideoWebPlugin

vue脚手架中集成插件

把官方资源包里的query-1.12.4.min.js、jsencrypt.min.js、web-control_1.2.5.min.js复制到vue项目public目录下,在index.html引入js

封装组件(vue2)
