With an annual passenger volume of 50 million, Frankfurt Airport is the largest airport in Germany. While the Rhine-Main region has profited from this circumstance, the further expansion is already on the way. The safety of passengers, aircraft and of the airport personnel takes top priority in this context. Among other things, the thermal imaging cameras by FLIR Systems, provided by Videor, ensure that no threat remains undetected. The camera systems installed by German project partner PKE Electronics provide clear and sharp images in absolute darkness, fog or smoke and feature a highly developed image processing technology, which guarantees an outstanding contrast independent of the dynamic of the scene.
The thermal cameras by FLIR Systems applied on the airport premises have 50-mm lens whose focus can be adjusted via RS-232 or RS-422 protocol. They offer a horizontal field of vision of 14 degrees. This allows the detection of a potential intruder even at a large distance. The images of the detector with 320 by 240 pixels can be shown on almost any display that is able to process composite video signals. All cameras of the SR series by FLIR Systems are available with different optical characteristics for specific application fields.
At Frankfurt Airport, hundreds of video surveillance cameras observe the activities on the runway or along the protective fence with a length of several kilometers. All safety-relevant areas within the giant compound and along the periphery of the airport are constantly surveyed. Protection against unauthorized access is one of the most important issues. If someone approaches the protective fence or cuts through it, fast detection is necessary to initiate the necessary steps. This is where the advantages of thermal cameras come into the picture: Common video cameras provide excellent images on clear, moonlit nights, but quickly hit their limits in fog, dense clouds or fully turned up landing lights. Thermal cameras do not need any residual light and generate clear images in challenging weather conditions as well as in total darkness.
