由于安防监控系统的历史状况(独立的小规模应用为主)，造成了安防监控设备的生产厂家非常众多，而且各个厂家都有自己的一套编解码和网络传输的水槽模具 u型槽模具 电缆槽模具 隔离墩钢模具 护坡砖模具 钢制闸门 螺杆式启闭机 卷扬式启闭机做法。但是也是因为这个现状的存在，所以要求大型监控系统平台能够接入多家厂商的设备。一者保护用户原有的投资；二者用户在新系统建设时减少投入提供解决办法。在建的大型监控系统都在这个方面做出了大量的努力，都接入了国内主流厂商的视频编解码设备，并且在用户端基本实现了对设备的透明化。
Due to the historical situation of security monitoring system (mainly independent small-scale application), there are many manufacturers of security monitoring equipment, and each manufacturer has its own set of coding and decoding and network transmission methods. But it is also because of the existence of this situation, so large-scale monitoring system platform is required to be able to access the equipment of multiple manufacturers. One is to protect the original investment of users; the other is to provide solutions by reducing the investment of users in the construction of new system. The large-scale monitoring systems under construction have made a lot of efforts in this aspect, and have access to the video codec equipment of mainstream manufacturers in China, and basically achieve the transparency of the equipment at the user end.
