Red Fox and Lemon Tree, two hotels in Aerocity which recently got partial clearance by Delhi Police to start operations, said they have installed state-of-the-art equipment to meet security requirements.
The hotels have installed facial recognition systems and 360-degree cameras. Besides, 3D walk-through systems have also been installed, which will guide security forces to their target in case of an attack. Other security measures in place include under-vehicle surveillance systems, fish-eye cameras in the basement and a security control room to monitor all activities.
