Although 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 a gateway to the outside world and transportation hub of the city, has always been on the top safety list of the government and all related authorities. Dahua Airport Solution is an intelligent security system that helps ensure the safety of the airports.

Airport security management challenges

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

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

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

Thirdly, it’s 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, which resulted in the runway being closed down for 80 minutes, the loss of which was estimated as at least 10 million dollars, not to mention collateral damages in the broader sense.

Unified airport security system

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

In terms of vehicle management: you can adopt all-in-one cameras to capture and recognise vehicle licence plates accessing the airport, which will trigger the alarm when they detect illegal, stolen, blacklisted, hit-and-run, crime-related and other suspects’ 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 ensure smooth service and respond quickly when things go wrong, even if it’s just something from the car got left behind due to carelessness.

In terms of passenger management: the same full coverage of the aforementioned security system also applies to passenger management, from one’s stepping out of the plane the car to one’s entering the terminal building and checking-in area and all the way to the last step to the boarding gate. The HD surveillance cameras endowed with deep-learning AI have world-leading accuracy in facial recognition and e-passport verification. Any suspect, dare they show up in the airport area, will at once trigger the alarm.

Thermal imaging camera has higher accuracy and less false alarm while directly providing video to verify

Dahua Airport Solution also takes care of another crucial part of 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 camera to keep the safety of the said area.

Complete security installation

Here is an elaborated example of Dahua’s solution to one specific airport, which covers a perimeter of 30 km and boasts an annual throughput of 30,000,000 people and 8,000,00 tonnes of cargo.

Dahua chose to use the 100mm lens with a resolution of 640 x 512 and set the installation height at 5M, which should be able to detect 1.8m x 0.5m people within 3000m. The perimeter will be well covered for intruder detection purpose with 10 cameras.

The intelligent analysis of IVS (intelligent video system) requires 10 x 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 so Dahua placed 30 there, which made it 40 thermal imaging cameras in total to solve the problem.

In future, Dahua will keep investing in R&D of cutting edge technologies into the realm of civil aviation video surveillance solutions

It should be noted that Dahua’s thermal imaging technology has the following advantages: 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 sensor and IR beam sensor, the thermal imaging camera has higher accuracy and fewer false alarms while directly providing video to verify.

Extending Dahua airport solution’s seamless integration

Dahua has established stable cooperation with world-renowned platforms such as Genetec, Milestone, Avigilon, AXXON, and 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.

In future, Dahua will keep investing in the R&D of cutting-edge technologies in the realm of civil aviation video surveillance solutions. With a mission of “Safer Society, Smarter Living”, Dahua will continue to focus on “Innovation, Quality, and Service” to serve partners and customers around the world.
