The electronic fence is said to be the most advanced equipment in the field of perimeter security. He has three advantages of remote monitoring, multi-level networking and equipment linkage, which can ensure the harmony of people's production and social stability from the source. However, how many people know the main components of the electronic fence, let's take a closer look at the five components of the electronic fence system. From the working principle and composition of the electronic fence, the electronic fence can be divided into five levels, namely physical layer, sensing layer, control layer, network layer and application layer.
