50 fake alarms by virtual fencing every day at Delhi Airport
The Perimeter Intrusion Detection System or virtual fencing at Delhi Airport raised over 50 fake alarms every day before its sensitivity was reduced, according to reports. An official said the fencing continues raising false alarms, but CISF personnel follow security protocol each time and check the intruder alert. Notably, the â¹35-crore fencing project has detected intruders in the past.
