使用条件
一.、引入依赖文件
jsencrypt.min.js
jsWebControl-1.0.0.min.js
注：必须在与 vue 的 根 index.html 文件中引入， main.js 中引入无效；
依赖文件及demo：下载
二、 template
三、methods
/* 获取视频code */
async getVideoCode() {
this.realTimeData.videoLoad = true;
const params = {
area: "",
enterprise: this.realTimeData.Warehouse.enterpriseName,
street: "",
};

cameraIndexCode,
}));
this.realTimeData.videoConfig = videoCode.map((item) => {
return {
code: item.cameraIndexCode,

},
/* 创建插件实例 */

//启动插件服务成功

/* 获取公钥 */

}),
};

},
/* 视频流RSA加密 */

}),
});
this.realTimeData.videoLoad = false;
},
/* 销毁视频实例 */
getDestruction() {
this.plug.example.forEach((item) => {

},四、使用效果图、功能：
1.实时监控 / 2.截图 / 3.录屏 / 4.摄像头控制 / 5.语音指挥（硬件支持）/ 6.即时回放
