我们这里选择V3.3版本

文档地址：https://open.hikvision.com/download/5cda567cf47ae80dd41a54b3?type=20&id=4c945d18fa5f49638ce517ec32e24e24

解压过后，会有三个文件夹

在docs中，点开Demo使用说明，按照流程先测试下，你的摄像头能不能调通

能够调通之后，我们再去正式在我们项目中进行开发。

步骤一：项目html文件中引入js依赖

我是将js依赖放到了public中

html中引入

步骤二：安装HCWebSDKPlugin.exe程序

步骤三：新建vue组件，将下面代码放进去，修改IP、用户名和密码

<template>
    <div class="hkv">
        <!-- 选择摄像头 -->
        <div>
            <p>选择摄像头</p>

                <el-option v-for="item in channelData" :key="item.id" :label="item.name" :value="item.id" />
            </el-select>
        </div>
