如果需要在互联网(公网)集成设备实现视频预览回放、语音、配置控制、报警事件等功能，当前的集成方法有：
1）推荐使用我司云曜开放平台，云曜平台支持GB/T28181国标协议、部标协议、萤石协议、NB-IoT协议以及第三方私有协议等各种协议和类型的设备接入，同时直接提供云端API接口（例如H5、小程序视频直播）供三方集成，集成简便快捷。云曜平台的对接文档地址：
服务专用热线是0571-87006061或者进入云曜官网https://www.hikyun.com/index直接留言咨询。
2）可以使用设备网关，资料详见：
https://open.hikvision.com/osp#%E8%AE%BE%E5%A4%87%E9%9B%86%E6%88%90%E7%BD%91%E5%85%B3
有固定IP地址的Windows或者Linux服务器上直接安装运行网关，设备使用ISUP5.0协议注册添加到网关，然后三方平台或者应用可以使用HTTP/HTTPS协议和RTSP协议对接网关，集成方便快捷。
3）如果不使用我司平台软件或者网关，自己开发所有接入和转发服务，则可以使用设备网络SDK（设备有固定IP或者域名的情况）或者ISUP SDK（设备无固定IP或者域名的情况）动态库接口和硬件设备对接，SDK包含服务器和设备之间交互的接口，设备管理、流媒体转发等均需要自行实现，具有一定的开发工作量。资料详见：
https://open.hikvision.com/osp#%E8%AE%BE%E5%A4%87%E9%9B%86%E6%88%90SDK
1、确定对接方式用
监控设备里启用：使用ISUP协议，填写服务端的网关IP，端口（这里比较坑，默认是7660，实际是7661，导致设备一直没法注册成功。）
服务器端：安装海康的Gateway网关
2、服务端Linux系统里安装海康的Gateway网关（官网下载）
./install.sh --port=81
Checking ports completed. Port 81 will be used.

FirewallD is not running
2、设备注册成功后，按开发文档调试
打开服务端的管理界面，添加设备
常见问题：
设备离线：等待设备注册到网关
如为isup5.0登陆密钥错误请修改密钥后重试
如为等待设备注册到网关请检查：
①如果使用ISUP5.0添加设备，部署网关的服务器防火墙是否关闭
②如果涉及端口映射本地测试，设备是否能正常注册上线
3. 收集网关日志后,收集相关信息发送到SDK邮箱进行排查.
常见问题：
1、视频web查看，wss协议如何访问。
做域名video.aa.com解析到DVR所在主机的IP（没有公网，做公网映射，443接口，因为80端口运营商早就封掉了，所以在路由器端做81端口映射，443正常）
jssdk里用video.aa.com访问各通道信息。

2、device-gateway里的nginx启动报错
删除nginx下的nginx.pid,error.log,右下角deviceguard服务先stop service,再start service.
也有可能是权限问题，因为ssl证书到期，更换了cert和key文件，给这个2个文件，安全里几个角色，都给完全控制。
