Dahua Airport Solution features thermal imaging technology

Hangzhou, China

Dahua Airport Solution is a unified security system combining multi-functional HD surveillance cameras with deep-learning AI.

Though it has been statistically proven that taking a plane is no more risky than taking a bus, people do have reasons to put extra caution on air travel safety, especially in a time replete with terrorist threats. A major line of defence must be the various sections of the airports, which, as the gateway to the outside world and transportation hubs of the city, has always been at the top of the safety list for governments and all related authorities. Now, Dahua has launched its Airport Solution, an intelligent security system to help ensure the safety of the airports.

All airports, large or small, suffer from similar difficulties in maintaining safety. First of all, it requires a complicated collaboration of multiple (sub) systems such as the monitoring system, alarm system, access control system, network transmission system and management platform. As it is widely known, the more steps and players involved, the higher the likelihood for a mistake to occur.

Secondly, airports in fact include a variety of places such as the terminal area, parking lots, office areas, freight area, front desk area (including the square in front of the terminal building), the flight area, the hangars, the perimeter area and so on, each of which operates on a vertical management system. Yet due to the diversity of places and the complexity of personnel and cargoes coming in and going out in huge flows, there are many risky elements to control.

Thirdly, it is not only about accuracy but also about swiftness when it comes to airport security. Safety should bring efficiency and not the other way around. For example, in April 2017, a drone flew into Chengdu Airport and resulted in the runway being closed down for 80 minutes, after which it was estimated that this incurred losses of at least 10 million dollars, not to mention collateral damages in the broad sense.

Designed to solve all the difficulties mentioned above, the Dahua Airport Solution is a unified security system combining multi-functional HD surveillance cameras with deep-learning AI that can analyse the big data to get to the target, be it a car, a face or a series of numbers.

In terms of vehicle management all-in-one cameras can be used to capture and recognise license plates of vehicles accessing the airport, which will trigger the alarm when detecting illegal, stolen, blacklisted, hit-and-run, crime-related and other suspect vehicles. Covering the whole route of a vehicle (from entrance highway, to parking lots and then to exit), the surveillance system can effectively assist security guards and police (especially when there is a lack of which) to keep a smooth service and respond quickly when things go wrong, even if it’s just something from the car that was left behind due to carelessness.

In terms of passenger management: the same full coverage of the aforementioned security system also applies, from people stepping out of the car to entering the terminal building and check-in area and then on all the way to the last step at the boarding gates. The HD surveillance cameras with deep-learning AI include accurate face recognition and e-passport verification. Any known suspect, if he dares show up at the airport area, will at once trigger the alarm.

The Dahua Airport Solution also takes care of another crucial part of the airport that is the perimeter area. Since there is basically no light to illuminate the area, it is even darker than the apron. One must resort to special equipment like thermal imaging cameras to keep the said area safe. According to the thermal imaging calculation, an elaborated example of Dahua’s solution is one specific airport, which covers a perimeter of 30 km and boasts an annual throughput of 30,000,000 people and 8,000,000 tons of cargo.

Dahua chooses to use the 100mm lens with a resolution of 640 * 512 and set the installation height at 5M, which should be able to detect 1.8m * 0.5m people within 3000m. The perimeter will be well covered for intruder detection purposes with 10 cameras. The intelligent analysis of IVS (intelligent video system) requires 10 * 10 pixels, under which condition, each thermal imaging camera can detect and analyse objects within 400m. There is in total 12km of perimeter length in need of such cameras 30 cameras were placed there, which made it up to 40 thermal imaging cameras in total to solve the problem.

Dahua’s TPC-PT8620C thermal camera has the advantages of PTZ function, long distance surveillance (which can detect a vehicle 8.8 km away), long distance zoom, binocular lens (optical and thermal imaging lens), strong intelligence (which can detect intrusion) and so on. Compared to alternate perimeter protection equipment on the market today, such as vibration fibre sensors and IR beam sensors, thermal imaging cameras have higher accuracy and less false alarms while directly providing video to verify.

Dahua has established a stable cooperation with world renowned platforms like Genetec, Milestone, Avigilon, Axxon, ISS, infusing Dahua’s Airport Solution with more possibilities. Supported by strong R&D resources and good working relationships earned in multiple previous collaborations with partners, Dahua can ensure seamless integration whether it’s front-end IPC or back-end NVR, fulfilling different demands of clients and building a sound security system for the airport.

Going into the future, Dahua intends to keep investing in cutting edge  R&D technologies into the realm of civil aviation video surveillance solutions.
