Hidden version is intended for cases, when it is required that the fence safeguarding is not visible. The detectors are installed inside the posts in the upper part and connecting cable leads also inside the posts and then underground between the posts (or as the case may be on the foundation wall or directly in the fence frame). The sensor itself is placed in a metal holder with springs in order to be able to use it in the posts of various dimensions. The Hidden version is more difficult to be installed, the Hidden version detectors are supplied not connected and the wiring must be prepared when the fence is installed. In certain cases it is possible to lead the cable on the top of the fence or e.g. in the pipe on the fence. In this case the cables are not so well protected, but the detection is not visible at first sight and the installation is easier compared to the standard solution.
