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.
