Abstract: The present invention relates to a system for detecting an intrusion attempt inside a perimeter defined by a fence including panels attached onto posts, comprising a means for detecting shocks and/or vibrations (4), which is connected to a remote station (7). Said system is characterized in that it comprises at least one housing (1) including at least one central processing unit or CPU (2), which is connected to at least one memory unit (3), to at least one shock and/or vibration detector (4), and to at least one field bus (5, 6) and/or at least one video bus (27, 28), each housing (1) being self-contained and connected to another housing (1) and/or to at least one remote station (102) for transmitting at least one computer file generated by the central processing unit (2) when a shock and/or vibrations are detected by one of the housings (1).

Abstract: A gabion includes panels of metal meshes that can be assembled so as to form a casing for receiving a bulk of filler material such as pebbles, natural rock fragments, wood chips or the like and/or a mixture of said materials. The gabion further includes at least one flexible sealed pouch provided with gripping members and configured to be inserted between the assembled panels.
