记录一下使用Java的SpringBoot+大华SDK在智慧公厕项目中使大华惠智双目半球网络摄像机DH-IPC-HD4140X-E2获取人流量统计数据

首先根据说明书登录摄像头，一般摄像头都有自己的账号和密码(可能是admin admin 也可能是admin 888888 还有可能是admin 12345)，有IP的(可能是192.168.1.108)，在同一个网段内浏览器访问摄像头的IP就可以访问web页面

**使用windows系统自带的浏览器Microsoft Edge 谷歌浏览器也可以，主要是要安装插件**  
![myw][]  
![myw][myw 1]  
下载安装插件(如果电脑之前安装过就可以不用安装)  
![myw][myw 2]  
![myw][myw 3]  
![myw][myw 4]  
安装完成之后 重启浏览器登录(更保险)  
可能有提示要加载，那就允许  
![myw][myw 5]  
![myw][myw 6]  
![myw][myw 7]  
设置人流量统计的相关参数  
**首先在设置 智能方案里把图标点亮**  
![myw][myw 8]  
在设置-人数统计里选择人数统计  
![myw][myw 9]  
**绘制区域和绘制方向线 绘制区域表示人流统计的区域，只有这个区域内的才统计的，绘制方向线，这个默认是入的方向线**  
**参数设置进入和离开人数需要打钩，灵敏度这个的配置需要根据实际来确认 人数统计报警的进入人数和离开人数需要设置成1，滞留人数不需要设置(这样用程序去监听的时候就能被动获取报警数据)**  
![myw][myw 10]  
![myw][myw 11]  
布撤防配置  
![myw][myw 12]

标定配置 安装高度和安装角度  
![myw][myw 13]  
自动维护配置 这个很关键，必须要配置，不然这个摄像头运行时间过长会被卡死的，可能是数据满了  
![myw][myw 14]  
网络设置 根据实际需求设置IP地址  
![myw][myw 15]

首先去官网拿到开发需要的SDK

> https://support.dahuatech.com/tools/sdkExploit

![myw][myw 16]  
**新建一个SpringBoot项目后调用sdk，在这里使用的是win10 64位的，sdk需要重新封装，去除gui方面的那部分代码**  
SpringBoot调用sdk的核心代码

放在SpringBoot启动页面内启动

DaHuaNetSdkManCountThread daHuaNetSdkManCountThread = new DaHuaNetSdkManCountThread();
    daHuaNetSdkManCountThread.start();

启动后控制台输出
