Research on Storage Expansion Scheme for Metro HD Video Monitoring System
The design and operation period of a part lines in the Wuhan rail transit network is relatively long,cannot meet the Anti Terrorism Law ask for the storage period of public areas and key areas video surveillance image information to be no less than 90 days.The research is based on the actual operation of urban rail transit,a scheme for remote backup and storage of auxiliary code streams based on ONVIF protocol is proposed,storage expansion of existing HD video monitoring systems is realized.This scheme has been applied at a transfer station for a three lines of Wuhan Rail Transit,compared to local storage expansion solutions,it has the advantages of simple implementation,minimal impact on operations,and low transformation costs,it has certain guiding significance for expansion and transformation of HD video monitoring systems about storage for more than 90 days in urban rail transit.
