A fire detection system was installed in the National Park PIRIN in Bulgaria based on infrared technology. “In the framework of the project”Sustainable forestry and environmental protection by planting a forest fire early warning system and an information centre in the National Park PIRIN, Bulgaria”, financed by the Foundation European economic area (EEA Grants), was the fire detection system PYROLINE/PYROSOFT FDS” selected by DIAS infrared GmbH and installed. This system consists of three infrared cameras in the special weather-proof housing, paired with each a Visual camera. The weather-proof housing are mounted on Swivel Tilt Heads. The system is equipped with the corresponding control hardware and software. The units were mounted on extra 20 m built for this purpose high towers and follow the situation in the Park area of Vihren day and night without interruption”on an area of about 9000 ha.
