Hong Kong Airport’s unmanned patrol cars

Hong Kong International Airport (HKG) now has four Autonomous Patrol Cars (APC) patrolling the restricted area of the airport.

The airport uses the unmanned vehicles to patrol the border of the restricted area instead of airport security staff. It can monitor people intruding and alert the on-duty airport staff.

Currently, four unmanned APCs are in operation and patrolling the South and North Runways.

What APC does

The APCs detects if someone has entered the warning zone by using video analytics. When it detects someone within about three metres of the border fence, it issues a signal warning the person to leave immediately. At the same time, on-duty security staff are alerted and can assess the live situation through real-time video streaming. Security staff can also be deployed to the site if necessary.

In addition, the APC uses video analytics to examine barbed wire fence for irregularities during its patrols, alerting staff if maintenance is needed.

It can follow a set route and turn around automatically. It can also detect obstacles within approximately 10 metres and activate its brakes automatically.

How it works

The APC is modified from an electric vehicle and can travel up to 200 kilometers on a full charge. It is equipped with three radars, eight 8 high-definition cameras and 2 sets of differential global positioning systems (dGPS).

In addition, the APC is equipped with an independent safety monitoring system that enables staff to monitor its operation simultaneously to ensure that the vehicle operates safely and remains on its driving route.

The APC can continue performing its duty in inclement weather, even typhoons. APC can withstand a wind speed of 180 kilometres per hour. It worked successfully during the typhoon hitting Hong Kong in October 2021.


The APC comes from Teksbotics, a Hong Kong-based autonomous driving solution provider, and its Chinese technology partner UISEE.

Security at China’s Airports

The APC is a fine looking machine but it cannot compare to AnBot, the robot with the cattle prod at Shenzhen Airport.
