The invention relates to a universal network video monitoring device access method and apparatus based on an SDK abstract layer. The method comprises the following steps: carrying out device class abstraction and package by adopting an abstract factory design mode, carrying out device function abstraction and package and decoding play abstraction and package by using the obtained device abstraction class to obtain device function SDK and decoding play SDK, packaging the device function SDK into a device function SDK plugin of a unified interface, and packaging the decoding play SDK into a decoding play SDK plugin of the unified interface; therefore a device client can develop a network video monitoring device by means of the device function SDK plugin and the decoding play SDK plugin, n order to access the network video monitoring device after necessary development, the demand of uniformly dispatching the package and dispatch of SDK when networking the network video monitoring device can be satisfied, the networking of the network video monitoring device and the secondary development of SDK are facilitated, and the application range is wide.
