In order to solve the problem that the existing video survillance in the fully- mechanized mining face was mostly fixed, and can not guarantee the omnidirectional observation of the working surface equipment during the movement , this paper proposed the development of a smart cloud camera for the fully-mechanized mining face. It is a system solution including building video camera compression, motor drive design, infrared fill light, stepper motor hardware and at the same time, the PIZ control program, the preset point inspection algorithm, and the focus control algorithm were developed. On the basis of satisfying the function of the cloud platform, the intelligent functions such as the defogging algorithm, the ROI region of interest calibration algorithm, and the optical flow motion tracking algorithm were added to realize the motion perception of the hydraulic support and the shearer on the working surface as well as the intelligent alarm of personnel violations or equipment anomalies. It is also possible to obtain a clearer image by defogging through the dark channel in the process of cutting the coal. The equipment was installed and applied in various working faces such as Huangling, Yankuang and Shendong Group and the results show that the itelligent cloud camera can replace the original cloudless camera, reduce 50% of the working camera equipment，and provide assistance for the remote visual operation of the well. The application ffect is good.
