## 海康摄像头对接，通过海康综合安防管理平台对接 ##

### 1. 海康综合安防管理平台介绍 ###

#### 1.1 官网介绍 ####

![在这里插入图片描述][029caabf9f744190bf24736e3be688d2.png]

#### 1.2 个人理解 ####

综合安防管理平台部署之后，有2个系统，一个是综合安防管理平台：是用户端系统，一个是运营中心：是综合安防平台的后台管理系统，可提供api与业务平台对接，实现实时预览、录播回放、语音对讲、报警订阅等功能。

#### 1.3 综合安防管理平台 ####

##### 1.4 运行管理中心系统 #####

## 2. 需求 ##

通过对接综合安防平台API实现摄像头的实时预览，录播回放，语音对讲，安全帽监测

## 3. 对接步骤 ##

### 3.1 运行管理中心创建合作方并授权对应的api权限 ###

![在这里插入图片描述][95a6612939604ee1b6097c411bca210e.png]

### 3.2 获取合作方的秘钥 ###

![在这里插入图片描述][c5457f585c474b548fb41a849f62d6b5.png]  
说明： 该秘钥是获取api权限的秘钥

### 3.3 拿到该秘钥，想要调用对应API接口还需要获取某一个摄像头的主键，cameraIndexCode ###

#### 3.3.1 官网api地址 ####

拿到对应的摄像头的主键cameraIndexCode,保存到数据库，后面调用实时预览接口，对应哪一个摄像头设备，用到这个cameraIndexCode

### 3.4 拿到该秘钥，就可以调用对应的实时预览接口，获取实时预览的串流url ###

#### 3.4.1 官网api接口地址 ####

根据返回值中的url,放到vlc播放器中可测试是否正确（点击媒体-打开网络串流）  
![在这里插入图片描述][6c6866c5e57c40928e21829433f0cbb9.png]  
测试正确，播放正常，把该yrl返回给前端，让前端调用h5播放器，播放该url即可。
