To ensure the safety of airport and air transport, the country and the world's major airports are increasing security and security systems construction investment, the escalation of security systems, iris, face recognition, smart visual audio analysis technology, a variety of security technologies and products continue to be applied to airport security systems, construction of the airport security will subsequently ushered in a new round of high tide.

Airports, particularly large and medium-sized aviation hub airport as an independent city, region, airfield, terminal, passenger and cargo traffic and aircraft movements volume, if only by artificial safety monitoring management, it is difficult to work, have to rely on the advanced technical means of prevention, early detection, early to stop the insecurity nipped in the bud. It can be said that if there is no security system to support the safe operation of the airport is unimaginable. In the whole airport security systems, video surveillance systems is particularly important, with a front-end points, the distribution of the common characteristics of wide.

User application background

Nanchang Changbei International Airport was founded in October 1996, in Nanchang, Jiangxi Province, north China Route airport. In 2007, the Nanchang Changbei International Airport expansion project started officially opened to traffic in 2009. This expansion project is to build a 100,000 square meters of new terminal (T2 terminal), the existing runway from 2800 m to 3200 m, apron machines to over 50 to meet the Jiangxi Province, continue to increased air throughput. T2 terminal is completed, the entire airport rating upgrade to 4E, the full weight off and landing of Boeing 747 and other large civil aircraft, assume a very important aviation hub role, has also become an important window of Jiangxi Province, opening up and strengthening of foreign economic and trade cooperation and exchange , made an important contribution to promote the economic and social development in Jiangxi Province.

Changbei Airport Terminal T2 newly built one with world-class terminal, the requirements of the security system is also very high. How to create a set of reliable, stable, advanced and compatibility with a good monitoring system, to become the focus of designers to consider.

Video surveillance camera selection program

Nanchang Changbei International Airport Terminal T2 used a total of 340 I-channel IP surveillance terminal for a particular focus on monitoring areas, the camera function selection and design are different. As follows:

T2 terminal

Sent the living room, then the living room

A visitor hall and pick up the hall is the focus of the entire terminal control area, you need to take into account the local characteristics of each person's activities in detail and clothing face. How to ensure access to these minutiae, a smooth, clear, high-quality monitor screen, is the focus of the monitoring of this region. In a typical surveillance scene, we can conclude that the demand characteristics of the following points:

(1) monitoring the area and a wide range of Wide venue of the visitor out of the hall and pick up the hall, the flow of people-intensive requirements of the camera's depth of field, wide field of view, a full range of no dead key monitoring and man-mark anywhere on a particular person or thing.

(2) scene brightness, strong contrast and backlight obvious. From the terminal building design considerations, a visitor lobby and pick up the hall with a steel frame structure design, the outside, full transparent glass curtain wall. During the day the sun directly through the glass wall into the Terminal, direct sunlight, as well as marble face the reflection of light, strong backlight monitor the scene of the camera, light and dark contrast within the scene, so the camera with a certain degree of wide dynamic backlight compensation function.

(3) night lighting conditions, monitor the scene illumination is not enough. One o'clock to five a day turnaround time for the Nanchang Changbei International Airport. During this time, less terminal within the staff, operating from the perspective of energy saving and environmental protection, and open a number of lighting facilities. In contrast, this time monitoring the scene illumination conditions are relatively poor, which is traditionally a high moment of the security incident. So the camera's sensitivity and noise reduction effects are higher, and the requirements of the minutiae and the trajectory of monitoring the activities of objects in the scene captured in low light environment, clear and complete.

Application features for the visitor out of the hall and pick up the hall, and ultimately using Sony network cameras and S. Among them, the Intelligent Network Dome Camera is equipped with a powerful 26x optical zoom autofocus lens, the flexibility to rotate horizontally and vertically, 1/4 inches SuperHAD CCD with high sensitivity and also has a voice alarm function, Additional features of the image flip function may be suitable for use on numerous occasions. The SNC-CS20 adopts Sony's newly developed ExwavePRO progressive scan CCD technology, with enhanced color filters, can provide a satisfactory high-quality images in a variety of conditions.

2-in counters

Check-in islands region is a key control area, passenger check-in votes for and need to take into account the characteristics of the face of the service operation and over-the-counter artificial-in counters, passenger check-in business. How to obtain the value of the machine operating conditions of the service personnel, and the exchange of passengers, customer facial features clear, smooth, high-quality monitor screen, is the focus of the monitoring of this region. Application characteristics for this occasion, the eventual adoption of the Sony network surveillance cameras, the SNC-DS10 and SNC-DS60. These Dome cameras are used Sony's newly developed ExwavePROTM progressive scan CCD technology, with enhanced color filter, in a variety of conditions, even a dim light environment, but also provide a satisfactory high-resolution The bright image of the monitor. In addition, the two fusion DEPA intelligent video analysis technology, with intelligent motion detection function and intelligent target detection per second 30fps 768 * 576 SD image, and also has a rugged housing to meet IP66 standards, to provide users with a very efficient and other high-level security monitoring.

3, the waiting room, quarantine

In the waiting room, the area of ??separation, we need to monitor the activities of the hall, waiting passengers and staff, and in a timely manner to prevent the occurrence of accidents and emergencies. Monitoring system must have a full range of monitoring perspective, for continuous observation of any direction suspicious persons or objects. In addition, some near the scene of the outside of the transparent glass curtain wall monitoring, brightness, contrast strongly likely to cause underexposed dark areas of the image is dark, can not see details of objects happens. This monitor the scene and sent to the living room and welcoming living room monitoring environment, considering their needs, eventually using Sony network cameras, which guarantees the PTZ rotation to achieve the level and vertical control at the same time, covering the monitored area. And Sony high-quality imaging technology and high sensitivity of the photosensitive device to solve a backlit black environment, human face.

4, baggage sorting, extraction area

In the baggage sorting and extraction of the region, the monitoring system needs to meet a particular surveillance area coverage (for example, the manual sorting of part of the baggage, the passenger in the baggage claim area, behavioral characteristics, etc.). If you can not do the full range of coverage in these areas to monitor the scene, in the event of lost baggage or related disputes, will directly increase the difficulty of such events in the follow-up treatment, and can not judge the basis for public security personnel to provide first-hand. Nanchang Changbei International Airport in the baggage sorting and extraction region using Sony network surveillance cameras, the one hand, to achieve seamless coverage of the relevant area, on the other hand to ensure the low light environment, but also to clearly distinguish between the personnel or characteristics and behavior of the details of the object, thereby indirectly guarantee the safety of the passengers' baggage.

1, parking

Nanchang the Changbei international airport supporting built four dedicated parking lot, are a social vehicle parking, taxi parking, the Chief Parking and business parking. On the ground outside the car park monitoring requirements, the demand characteristics of the following:

(1) region-wide monitoring. Outdoor parking area is large, and need the perspective of the camera, both near and distant vehicles.

(2) outdoor all-weather 24 hours of application. 6m high vertical pole parking cameras have been installed in the parking lot, whether it is extremely hot weather, cold weather or low temperatures, even encountered lightning storms and other inclement weather must also be able to weather 24 hours of uninterrupted work.

(3) low-light environments, clear capture any movement of the monitoring scene. In the environment under poor lighting conditions at night, the high incidence of accidents. In this environment, you need the camera with excellent low light performance, and the environment at night, can clearly capture any movement of the monitoring scene.

(4) have a certain degree of light inhibition. Environment at night compared to the surrounding environment, motor vehicle headlights turned on camera increased significantly, the camera has a certain light suppression. Otherwise, monitor the image will be bright one, can not look at the content of the image information, but can not see details such as motor vehicle license plate.

Integrated parking environment on the needs of the surveillance cameras, and ultimately using a Sony analog camcorder video camera to meet the stringent IP66 waterproof and dustproof standard, widely used in airport traffic, Safe City, energy and other industries. The use of Sony's high-sensitivity ExwaveHAD CCD, day and night conversion function in combination with optical IR filter, even in very low light can still get a bright image. In addition, the SSC-SD26P the horizontal resolution reach 540TVL, with 26 optical zoom capability and a certain degree of light inhibition image processing effects, nothing is completed the monitor screen. Operating temperature range from -40 ° C to +50 ° C, regardless of the bitter cold and scorching heat all year round to monitor.
