An 'aerostat balloon' developed by the Indian Institute of Technology-Kanpur (IIT-K) will be deployed for aerial surveillance in Ayodhya.
The USP of this balloon is that by positioning it at a height of 100 metres, a range of 4 to 6 km can be monitored and the activities happening in that area can also be recorded.
IIT-K's Assistant Professor Subramaniam said that the balloon's exclusive feature is that it can rotate in any direction.
The balloon, controlled by a remote, has a camera which can record even the minutest of occurrences.
The Uttar Pradesh Police are already using drone cameras to monitor activities in the holy city ahead of the Supreme Court verdict in the Ram Janmabhumi-Babri Masjid title dispute case.
