In comparison with the standard version, the detectors have been fitted with sturdier plastic boxes which have been designed for the attachment of armoured conduits with a diameter of 8.7 or 10 mm, so that the system can also be used in places where the system data collection lines must be protected better.

Special covers for the screw heads also greatly restrict the possibility of removing these unauthorised from the fence. For application, where you do not want to alert the intruder or it is necessary due to aesthetics there is a hidden version available.
