背景分析
视频监控整合人工智能技术，虽然在加强监控的同时也伴随着一些潜在风险，但是潜在的优点显然超过了缺点。且如今人工智能在算法与芯片领域的成熟及成本的下降，使得智能监控的商业化落地更加快速地普及，同时智能监控市场在寻求差异化竞争形成了百花齐放的形势。
国标GB28181视频流媒体服务平台
EasyGBS国标(GB28181)流媒体服务软件： 提供用户管理及Web可视化页面管理； 提供设备状态管理，可实时查看设备是否掉线等信息； 实时流媒体处理，PS（TS）转ES； 设备状态监测、云台控制、录像检索、回放； 提供RTSP、RTMP、HTTP-FLV、HLS等多种协议流输出； 对外提供服务器获取状态、信息，控制等HTTP API接口。
最近在开发GB35114的功能，我们在这里简单上传几个注册信令。目前只开发了设备和平台之间的协议，希望对大家有所帮助：
