Modern video surveillance in airports requires flexible solutions which fulfill stringent quality and security demands: distributed cameras, recording and transmission of video signals, live presentation, use of digital networks, intelligent picture processing, integration of audio channels and control as a video system or via a higher-order (often already existing) building-management system.
Due to the layout of modern airports with numerous separate buildings and areas, the need arises for multi-area surveillance systems with the flexibility to set up secondary control centers as well, for example. Emergency scenarios and the integration of mobile control stations also play an important role (e.g., PDA).
Requirements
-Implementation of a state-of-the-art video surveillance solution
-Flexible and scalable expandability and adaptation to future requirements
-Use of the most modern technologies available for networking, cameras and video technology
-Use of the most advanced algorithms for picture processing and event analysis based upon them (intelligent video analysis systems)
-Integration into the existing infrastructure
CCTV AIRPORT SOLUTIONS
Picture Generation
The new series of high-resolution color video cameras with Cam_inPIX technology from Dallmeier electronic are designed to fulfill the requirements of modern camera technology and are well suited towards use in highly complex video surveillance systems of airports, with their wide variety of operating conditions. In conjunction with Dallmeier picture transmission and recording technology, the operator is in control of a complete security system with the best components, fine-tuned to one another, from one source.
The cameras, which are distinguished by their ultra wide dynamic range, have an advantage over previously known methods in that they can show considerably more detail in shadowy and very bright areas of a picture simultaneously. When used with the software developed especially for the security field, cameras with Cam_inPIX technology also provide clear, high-contrast pictures in every situation, even in very difficult lighting conditions when monitoring different areas of an airport and its grounds.
Cameras in the Cam_inPIX series are attractive not only because of their outstanding picture quality, but also thanks to easy start-up and extreme user-friendliness. Their convenient factory presets offer optimum picture quality out of the box in almost any operating conditions. Subsequent changes to the presets or adaptation of individual parameters can be carried out with little effort directly via the video cable of a modern Dallmeier digital recorder or a PView station.
Due to their very large dynamic range, Dallmeier fixed and dome cameras are ideal for use in airport terminals, for example, in which a variety of lighting conditions (including direct sunlight) are found over the course of the day due to large-size glass facades. Difficult lighting conditions of this type are also dealt with on a continuous basis in the loading and unloading zones of freight terminals. At city-train stations, this newest generation of cameras also provides picture material which is highly suitable for secure surveillance of the platforms, even in backlit conditions.
In parking garage entrances and exits, Cam_inPIX cameras combined with Dallmeier CCTV intelligent video analysis systems guarantee secure detection and monitoring of vehicle number plates, even with the headlights of a car switched on. Dallmeier video cameras are used with intelligent video-sensor technology in the field of outdoor security. Suspicious people and vehicles are reliably detected and the security control center is alerted in any conceivable lighting conditions, even in rain, hale or snow, due to the excellent quality of the picture material generated.
Picture Processing, Transmission, Storage
The Digital Matrix from Dallmeier enables the transmission and recording of video and audio signals in broadcast quality via an Ethernet/IP network. Using this technology, which is based on the DIS devices, any number of cameras at an airport can be analysed, recorded and, if necessary, transmitted via the IP network. The implemented MPEG-2/4 compression enables camera pictures to be transmitted in real time and with the best possible quality and frame rate, even allowing convenient control of PTZ cameras. Recording also occurs in broadcast quality in ring memory, which is automatically overwritten after a preset time has passed (e.g. 14 days).
The DVS 600 is especially suitable for use as a recorder and video transmitter outdoors, e.g. for fence surveillance. It can analyze relevant video pictures and, for example, identify a person moving in a certain direction in a certain area as suspicious and alert the higher-order management system. The live picture is then switched to one of the surveillance monitors by the Digital Matrix. The most modern algorithms, such as object classification, ensure that the false alarm rate from ambient environmental influences is minimised.
In addition, the DI-Detector for intelligent picture processing is available for use inside the terminal or in the baggage claim area. This CCTV intelligent video analysis system enables for example the monitoring of static objects and can alert the central security office if, for example, a suitcase was set down in a critical area and left for a longer period of time.
In parking garages and near access points, the system enables identification of entering and exiting vehicles via Automatic Number Plate Recognition (ANPR).
All Dallmeier devices can be integrated into the system network and enable simultaneous recording and playback of any connected camera via the time-shift method (Triplex mode). PTZ functions can be used. Additional functions, such as slow-motion playback, scalability of picture quality, numerous playback functions and integrated picture filters for improvement of picture quality (e.g. with noisy camera signals) show the range of capabilities of our devices and predestine it for use in airports.
Dallmeier provides a variety of management systems for control of all the devices, and also different interfaces for integration into an existing infrastructure.

After two years’s extensive market research Copenhagen Airport selected Dallmeier’s Digital Matrix Solution. The company’s DIS -1 was chose mainly because of its excellent picture quality, the flexibility afforded by the system architecture and the ease with which the new equipment could be integrated into the existing systems.
COPENHAGEN AIRPORTS A/S
Located just eight kilometres southeast of the Copenhagen city centre, Copenhagen Airport is in Kastrup, a town on the island of Amager.
The airport is Scandinavia’s main airport, i.e. the transfer airport for air traffic between other parts of the world and the many national and regional airports in Scandinavia and the area south of the Baltic Sea.
Copenhagen Airport functions as the hub for Scandinavian Airlines (SAS) and belongs to the Star Alliance, a network of 15 international airlines that fly to a total of 772 airports in 133 countries. The airport is also the Scandinavian hub for DHL, the express air freight company.
The airport is owned and operated by Copenhagen Airports A/S, a company listed on the Copenhagen Stock Exchange. There are about 22,000 employees in the many different companies that together provide the services around Copenhagen Airport.
The three largest airlines serving Copenhagen Airport are SAS, Maersk Air and Sterling European.
Direct connections are available from Copenhagen Airport to a total of 127 destinations worldwide, seven of which are in Denmark, 20 are in other Scandinavian countries,78 are in other European countries and 22 are intercontinental airports.
DAUNTING CHALLENGE
Security requirements for airports of this size are enormous. Specifications included the use of the existing IT infrastructure as well as support for IP multicasting. These enable a video data stream to be transmitted into the network only once, yet the video can be viewed at many different points (control points and operations centres) simultaneously. By using multicasting the network loading is not increased, and the IP network itself ensures that all participants/viewers receive the desired CCTV picture.
The Linux operating system was another important factor when making the decision for the Dallmeier solution and because it is stored separately on a flash disk, which ensures high reliability of the total system.
More than 130 cameras at the airport are monitored, recorded, and, if necessary, their pictures transmitted via the IP network. By using MPEG-2 compression the camera pictures are delivered in real time, top quality and with high picture repeat rates, thus ensuring that control of PTZ or dome cameras is straightforward.
The broadcast quality video is stored in a ring memory which is automatically overwritten after seven days.
Dome cameras installed at the terminals’s check-in counters are moved according to preset positions. Fixed cameras are used to observe and monitor the gate locks and provide general observation around the airfield.
DIGITAL MATRIX FOR MORE THAN 130 CAMERAS
In the airport security control room 28 x DIS-1 systems act as receivers for the Digital Matrix. Live or recorded pictures from 32 of the 130 cameras can be displayed simultaneously by means of automatic control, event control or manual control. Other workstations can easily be added as required to receive pictures on a PC platform or an analogue monitor.
A preview on the PView screen offers a rough overview where four, nine or 16 cameras can be displayed simultaneously in a video split.
The current management is based on the new Dallmeier management system SeMSy Professional together with OPC. Dallmeier also provides many different interfaces for integration into higher level management systems or for their expansion, it would for example, also be possible to support further tasks such as the control of flight information displays.
TRENDSETTING TECHNOLOGIES
Nowadays international airports are always planning to expand their existing security systems, and Copenhagen Airport is no different. The importance of trendsetting technologies in the motion detection field is -- additionally to picture transmission and recording -- increasing more and more.
The Dallmeier DI-Detector, DVS 600 and SEDOR technology Dallmeier are part of a range of products which are involved in intelligent picture evaluation and analysis.
By using them it is possible to carry out event-controlled alarm switching more intelligently so that the camera pictures are evaluated according to different criteria -- the aim being to support the user and relieve him of some work.
In the airport world, besides perimeter fence monitoring where it is desirable to suppress false alarms caused by animals, lighting or weather conditions, another important current issue is deterring terrorism within terminal buildings.
By using SEDOR technology the Dallmeier DI-Detector can recognise the arrival or removal of static objects. This allows the system to identify an unattended suitcase in a terminal and to trigger an appropriate alarm.
However, other functions such as people counting at entrances and exits, number plate recognition at car park entrances and many other functions can also be implemented with the Dallmeier DI-Detector modules.
In conjunction with the Digital Matrix a powerful, intelligent security system can be generated which makes transmission, storage and evaluation of a multiplicity of cameras as easy as possible for the user.
