Nearly 29 CCTV cameras will be installed in and around the main base camp for Amarnath pilgrims in the winter capital of Jammu and Kashmir, said an official on Monday. The Yatri Niwas Bhagwati Nagar in Jammu serves as the main base camp for pilgrims from across the country before they leave for Kashmir to pay obeisance at the 3,880-metre-high holy cave shrine of Amarnath.
