The Delhi Metro Rail Corporation is installing state-of-the-art CCTV cameras at its new corridors that will become operational this year, taking the total number of cameras in metro network from the present 9,029 to more than 13,000. There are 183 operational stations in the Delhi Metro network, which will go up to 227 this year with the opening of the remaining new sections of the Magenta and Pink Lines Metro. DMRC and Central Industrial Security Force (CISF) together plan to provide a tight security blanket across all the new corridors and stations. Moreover, the new cameras being brought by the DMRC are technologically more advanced than the present ones installed at operational stations. CISF has two security control centres – one at Shastri Park from where Yellow, Red and Green Lines are monitored and the other at Metro Bhawan near Barakhamba Road, from where Blue, Violet, Pink and Magenta Lines are monitored. CCTV cameras are monitored by both DMRC officials such as station controllers and our personnel as part of parallel monitoring. The numbers of cameras required depend on the size of the station, interchange facility, crowd and number of exist and entry points.
