摘要： The present invention relates to a system for detecting a drone (1) around a building (2). The system comprises at least one lidar (3) to monitor the area around the building (2). The lidar (3) is installed on the building (2). The system further comprises a processing unit able to detect the drone (1) and localize it and to determine its trajectory from raw data generated by the at least one lidar (3). The processing unit is programmed with deterministic and/or artificial intelligent algorithms. The system further comprises a control unit to inform about the presence of the drone (1) around the building (2). The disclosure further concerns the use of a glass as a window or spandrel of a building in combination with at least one lidar (3) in order to detect a drone (1) around the building (2). The disclosure also concerns the use of a glass as an optical window of a housing of a lidar (3). The glass has an absorption coefficient at the operating wavelength of the at least one lidar (3) of less than 15 m -1 , preferably less than 10 m -1 , even more preferably less than 5 m -1 . Very transparent glass in the near infrared, with weak or no impact on its aesthetic or its color, can be obtained by combining in the glass composition a low iron quantity and chromium in a range of specific contents.
