The move comes in the wake of the February 21 twin bomb blasts, which killed 18 people and injured 106. Police officials working in the old city said CCTV cameras, particularly in vulnerable localities, could be of great help.
Currently there are fewer than 200 CCTV cameras in the city and all of them, barring six located near the trouble-prone Mecca Masjid locality, are used for traffic monitoring.
Police sources said the original plan was to install 5,000 CCTV cameras but the number was reduced to 3,500. Of these, 2,000 would be installed within the Hyderabad police commiserate limits, which cover the old city and part of Secunderabad.
Nearly seven weeks after the blasts, investigation into the case has made little progress and the National Investigation Authority, which took over the probe from the state police, has not gone beyond a few conjectures.
