Chennai airport still waiting for system to detect trespassers Updated: Updated: Tenders for its installation are likely to be floated soon Share Article Tenders for its installation are likely to be floated soon A few weeks ago, a vehicle going for rounds in the tarmac at the airport found a man roaming in the apron area. On enquiry, they found he had jumped onto the tarmac through Gate No. 6 from GST Road. This could have been avoided if a perimeter intrusion detection system was in place. The idea was mooted a few years ago but the system is yet to be installed. Tenders should have been floated already but it is not clear why there had been a delay and why it had not been implemented still.
