CCTV is just the beginning. People generally think that deploying CCTVs solves all the problems, but are they aware whether the camera is working or not? Keeping the analytics in mind, people generally spend a lot of money, but these are not much useful. A CCTV comprises of two things – one is real time surveillance and the other is post-facto surveillance. In real time surveillance, it is difficult to see things at a small place, and most importantly, even in commanding control centres, there is video blindness. In about 19-20 minutes, a person becomes 45 per cent video blind and in less than 44 minutes, he becomes 90 per cent video blind.
