While 10 CCTVs will be installed in and around the 17th century Mughal monument covering up to three km, 30 will be installed to cover a 4-km stretch from Shanti Van to the Red Fort police post.

According to a senior police official, the 10 CCTVs will cover the area where VIPs will sit, the passage and the area surrounding the monument. The CCTVs will be installed by August 10 and they will be there till August 15.

"This is not an unprecedented step. These steps are taken as such occasions are always the target of terrorists. We should not be caught napping," the official said.

However, he said, the security measures will be more tighter in the wake of terror attacks in Mumbai which claimed over 180 lives.

A ground-to-air security apparatus will be put in place for the Independence Day celebrations besides making the Red Fort area a no-fly zone.
