In UK, it is quite common to have remote-controlled entry points to even small offices. A visitor, whether in a vehicle or on foot, is required to press a button, whereupon he is asked to identify himself by intercom. When satisfied, the operator can open the door/gate/barrier remotely. It is perplexing why such sensitive organisations such as our GHQ cannot operate a similar system and why the lives of security guards are put at risk. A suitable entry system can even provide a facility where the operator can see the visitor on the screen. Speaking in a mike, the operator can ask the visitor all sorts of questions. He can be asked to take off his outer jacket or present his ID to a scanning device. Many lives can be saved by using such methods. KHALID A, London, November 9.
