Intrusion Detection Systems to be installed in all hyper-sensitive airports by 2023 – Here’s what we know

A safe and robust airport perimeter fencing acts as the very first line of defence against security risks and potential threats at airports. Failure to install one that meets all safety regulations could thereby result in an increased number of security breaches.

All hyper-sensitive airports in the country shall install the PIDS by December 31, 2023 as per minimum technical specification… Further, non-RCS greenfield airports shall plan installation of PIDS at design stage itself for the purpose of obtaining clearance of design stage security vetting in terms of rule 5 (3) of the Aircraft (Security) Rules 2011

BCAS stated in the circular which comes into force with immediate effect

According to a circular released by the Bureau of Civil Aviation Security (BCAS), all hyper-sensitive airports in India are advised to have a perimeter intrusion detection system installed by December 2023. While airports that come under the Regional Connectivity Scheme (RCS) will plan the installation at the development stage itself, Greenfield airports that don’t fall under the scheme will also have the system installed-the circular said.

Why has the government ordered the installation now?

According to the 2011 World Airport Traffic Report by ACI (Airport Council International), worldwide airport passenger numbers increased by 5.3% in 2011 to 5.44 billion and global passenger traffic is expected to top 12 billion by 2031.


While a fortune has been spent on internal screening measures, explosives detection systems and air cargo security for airports, the focus has been comparatively less on the actual physical security of the airport.

Timely detection and intervention of external threats would ensure the safety and the security of the passengers, crew, ground personnel, and the general public while also safeguarding against all acts of ‘unlawful interference with civil aviation.

Intrusion Detection System | How does it work?

While airports today feature advanced security measures which integrate multiple screening layers, body scanners and explosion detection tools, the actual physical security of the airport has been relegated to the back seat. With the growing incidence of sophisticated security attacks and evolving threats, it becomes highly imperative to plan the overall physical infrastructure in a way that drives actionable intelligence.

Perimeter security is both a fundamental and critical aspect of any airport security strategy.

As unique as every airport design is, how the perimeters of airports are protected, will have to be customised to suit each airport.

Traditional methods of protection include fence systems and fence alarms. They are often susceptible to false alarms and often while it sounds, the security breach is either in progress or has already occurred.

Radar and thermal imaging

Although they operate in different modes, it allows suspects to be spotted and tracked as soon as they enter pre-defined zones. Simply put, they can be monitored potentially while they are still beyond the perimeter and can be tracked if they cross it.

Taut wire

Taut wire signals fence movement or tampering, although it can be quite expensive over long distances.

Fibre optics

Fibre optic cable is designed to detect and pinpoint the location of intrusion anywhere on the airport perimeter fence, providing real-time reporting of intrusion. They require no electronics, power or infrastructure in the field, thereby making it impervious to external weather conditions and hence, no change in sensitivity and virtually no nuisance alarms

Access control system (ACS)

ACS is a subsystem that supports intrusion detection systems in controlling access to individuals to certain areas of an airport.

Volumetric sensing

Representative | Detection Technologies Blog

Volumetric sensing monitors the physical space adjacent to fence lines for system penetration. Typically infrared, microwave or proximity sensors but can also be CCTV with Video Analytics.

Video Analytics analyses CCTV video for specific data, behaviour, or objects and is not to be confused with video motion detection (VMD)-they are prone to nuisance alarms.

The massive scale of infrastructure and the magnitude of people concentrated in a particular location makes airports worldwide attractive targets for terrorism and other forms of crime. Implementing one or more of these solutions, would ensure timely prevention of security breaches and hence avert loss of life or property.
