Abstract: To solve the key difficulties of video surveillance in the land resources environment,wegive the scheme with different levels, the system architecture and key technologies analysis for land resources monitoring including camera selection and mobile edge computing. Since the position of the camera in the video surveillance is fixed and the data transmission is mainly concentrated in the uplink, the video surveillance data transmission can be enhanced by deploying more antennas on the side of base station and using directional antennas on the camera.We demonstrate by simulations for the data transmission performance and the improvement strategies of video surveillance in U-LTE network and from the view of throughput, both strategies are effective and can be implemented.

Key words: video surveillance, unlicensedLTE;throughput, mobile edge computing
