On the Perimeter Protection, Secplan has shown its systems, including G-Fence and Solaris. G-Fence detects cutting, climbing over or breaking of the fence, ignoring weather-related influences (rain, wind), passing vehicles or electromagnetic interference. The sensors are spaced 3m from each other, directly integrated in the cable. Each sensor detects changes in movement or vibration of the fence and locates them with an accuracy of 3m. Each sensor is integrated in the cable with its own detection algorithm and communicates directly with the associated control unit. Thanks to the spatially distributed intelligence, the sensors automatically adjust to the fortified fence. Solaris on the other hand is the first autonomous solar powered light matrix and active radio network. Each column is equipped with a Radio Transceiver and uses a communication protocol in a secured wireless meshed network. Thanks to the embedded Web server it can be accessed both locally and remotely. [www.freilandueberwachung.de]
