The safe city intelligent monitoring system is an intelligent security system that automatically establishes a monitoring alert area by acquiring monitoring images, and dynamically detects moving targets in the area to achieve comprehensive or three-dimensional visual monitoring and alarm. In safe city roads, according to the security monitoring points of each city, the video and audio signals are converged to the optical fiber convergence point of the police station through optical fiber. The monitoring staff of the police station convergence point can use the local video transmission monitor of the video recorder to transmit the digital video to the remote branch for monitoring. center. HANSUN uses HX2024W-8SFP-410G, HX202-SSC-20, HX2002-8SFP in the solution, and installs fixed-point cameras, fast domes, decoders, alarm probes and other equipment according to the security monitoring points in each city, and transmits audiovisual signals through optical fibers. Converge to the fiber optic convergence point of the police station, and transmit the digital video to the remote branch monitoring center to ensure the monitoring of each monitoring point is in place and improve the efficiency of network data transmission.
