最近有个需求是将海康的摄像头视频画面传到我们平台上作为一个全干工程师网页后端都要我来做。
相关网址 海康开发平台 资源中心 综合安防管理平台
我这里用的是综合安防管理平台
网址 综合安防管理平台 API OpenApi 下载 获取Appkey和Secret/密码和密钥
具体步骤可以看这个 python调用海康视频汇聚平台API获得所有摄像头设备编号、实时播放rtsp地址、回放rtsp地址 保证有默认合作方 拿到Key和Secret
测试
随便找个Api测试 测试成功有返回信息就可以了
个人魔改工具类
还是不喜欢全局静态的写法

海康视频接入
海康视频接入有两种方式第一种是有web插件第二种是无web插件。无web插件弄起来特别的麻烦所以我们主要讲第一种。
获取摄像头Id
选择分页获取监控点资源 选择个数多一点 下载海康Web插件 海康开发平台下载地址 视频Web 插件 V1.5.2直链下载地址 下载完成之后我们可以看到Demo选择合适的自己试一下 原生Html导入
我这里已经封装好了我直接拿出来了
网页设置
我将很多无关都隐藏了
