Delhi is looking to up its guard with electronic eyes keeping a strict vigil. Under a project of Delhi's IT department, the city will get 50 mega cameras, fitted on the roof tops of multi-storeyed building across the national capital territory.

Each of these cameras will see all that happens within a range of 5 km,and ehnce will help alert the authorities about events or activities that demand scrutiny or action.

Thus, the authorities can rush in to check or respond to crimes, unauthorized constructions, disruptive activities including terrorist attacks and natural disasters, relief and rehabilitation.

The input provided by the mega cameras will be of much use for the police, revenue department, disaster management authority, fire service.

During a presentation made by the department to Delhi chief minister Sheila Dikshit and chief secretary Rakesh Mehta on Thursday, Dikshit instructed the department to continue its innovative projects to ensure e-enabled services in Delhi.
