Over 70 companies of paramilitary forces and more than 15,000 police personnel will be deployed across the national capital for Republic Day celebrations, an official said. The city will be monitored by drones and CCTV surveillance, and cyber-specialist officers will be deployed to oversee operations. Multi-layered security arrangements, including six layers of checking and frisking, barricading, and thousands of CCTV cameras with Facial Recognition Systems (FRS), will be in place.
