Indira Gandhi International Airport in Delhi, India is protected by the high-tech security system. However, the virtual fencing system is yet to prove its efficiency, as currently it is more effective in raising a false-alarm than detecting threats, India Today writes.

The Perimeter Intruder Detections System (PIDS) is based on technology producing invisible laser rays. When touched they set off an alarm. The device is controlled by the Airport Operation Control Centre that usually sends security team when the alarm sets off. The system, whose purpose is to detect trespassing, provides the second layer of security at the Delhi airport.

Prior its establishment it was expected that the system would help to secure the airside perimeters and areas accessible to aircraft as well as protect against intrusion and trespassing.

However, the unvented outcome the Delhi airport now struggles with is that the system causes up to 50 fake alarms a day, while other sources even report up to 1500 (!) fake alarms a day prior the system was disabled in certain zones. In order words, the virtual fencing system instead of increasing airport security is getting it more... tired and numbed.

Can’t live with it, can’t live without it

It would be unfair to call the system useless. For what it’s worth, the system has actually done precisely what it is installed to do: caught a trespasser. PIDS system informed the central security force after a man climbed the Delhi airport wall.

Despite that the authorities are considering the options to get rid of the system or at least get yet another security system implemented. During the Bureau of Civil Aviation Security meeting it was even proposed to replace the virtual fencing system with “power fencing”.
