SpringBoot+Vue+HIKVSION实现摄像头多选并多窗口预览(插件版)：
SpringBoot+Vue+HIKVSION实现摄像头多选并多窗口预览(插件版)_霸道流氓气质的博客-CSDN博客_springboot 摄像头
上面可通过单个摄像头的ip、端口、用户名、密码等参数实现单个摄像头预览。
但是缺点是如果是插件版的摄像头视频对接，需要将浏览器切换成兼容模式或者使用IE浏览器进行预览。
但是如果将摄像头添加到海康威视的综合安防管理平台(iSecure Center上)，则可以不用切换兼容模式进行
视频预览。
对接的文档以及示例代码可以去海康威视官网寻找和下载
注意选择对应的版本，版本查看方式在安防平台中点击右上角菜单的按钮，选择关于
然后点击关于就可以看到版本

SpringBoot+Vue+iSecure Center（海康综合安防管理平台）实现视频预览 – 霸道流氓 – 博客园
实现
1、下载示例代码之后找到demo下的preview的html，这里以1.1.0为例，不同版本代码目录可能不同。
2、打开该预览demo页面发现预览需要一些参数appkey、secret、API网关地址IP、监控点编号等关键信息。
3、appkey等调用接口认证的相关参数获取。
在安防平台对应ip的8001端口进入运行管理中心，或者可以直接通过安防平台的关于直接点击跳转
然后状态监控-运行管理中心-API网关-参数配置-API管理
然后新建合作方，就可以获取到appkey和secret
4、监控点获取
综合安防管理平台右上角点击菜单选择系统管理-设备管理-视频监控-监控点
点击每个摄像头的编辑按钮即可以看到监控点编号
5、视频预览demo运行
首先确保这个监控点在安防平台本身是能直接预览的，会提示你安装插件，安装完插件之后可能需要重新浏览器或者电脑。
然后在预览htmldemo中配置以上的参数并进行预览测试。
6、在示例代码下能成功预览则进行VUE代码改造。

若依前后端分离版手把手教你本地搭建环境并运行项目_霸道流氓气质的博客-CSDN博客_若依前后端分离框架搭建
上面在搭建起来前后端分离版的项目后，新建一个数据库用来存储监控点的编号信息等。
DROP TABLE IF EXISTS `bus_platform_surveillance_video`;
CREATE TABLE `bus_platform_surveillance_video` (
`id` bigint(0) NOT NULL AUTO_INCREMENT COMMENT '序号',
`name` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT NULL COMMENT '名称',
`monitory_point_number` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT NULL COMMENT '监控点编号',
`area_name` varchar(255) CHARACTER SET utf8mb4 COLLATE utf8mb4_0900_ai_ci NULL DEFAULT NULL COMMENT '位置',
PRIMARY KEY (`id`) USING BTREE
) ENGINE = InnoDB AUTO_INCREMENT = 22 CHARACTER SET = utf8mb4 COLLATE = utf8mb4_0900_ai_ci COMMENT = '带有监控点编号的摄像头' ROW_FORMAT = Dynamic;
SET FOREIGN_KEY_CHECKS = 1;这里主要建了一个表用来存储摄像头监控点的编号以及坐标信息(业务需求)。
然后根据数据库生成后台代码，这里不再赘述，只需要简单的增删改查的接口。
7、前端代码
Vue的预览代码大部分就是参考其官方的预览html的demo进行的改造。
