REAL-TY INTELLIGENCE

For 21 years till 2011, Vikas Gosain worked with the Indian army. He was a Gorkha Regiment infantry officer. He has worked with civilian organisations since, and currently manages security operations for Bharti Realty, a real estate developer.

Feed from 314 cameras in the building are beamed to this centre live. Every person and car entering its perimeter is scanned and the images are processed here in real time. “We cannot have a blind spot,” Gosain says, as he proceeds to explain the technology behind real estate in high security areas. Every vehicle entering Worldmark has to pass under a vehicle scanning system whose high-resolution cameras scan the underbelly of the vehicles for any abnormality in seconds.

Facial recognition technology is used to identify miscreants entering the premises. A database of criminals and suspects, received from Delhi Police, is fed into a software system. Its algorithm matches every face spotted by the camera against the data stored. A match of more than 80 per cent is shown as a pop-up on the screen in the control room. New facial recognition technologies use deep learning, a branch of machine learning in which the algorithm learns from the
