Description

Technical Field

[0001] The utility model belongs to the technical field of electronic fences, and in particular relates to a novel electronic fence. Background Art

[0002] Electronic fence is currently the most advanced perimeter anti-theft alarm system. The system is mainly composed of two parts: the electronic fence host and front-end accessories. Usually, the electronic fence host is outdoors and installed along the original wall (such as brick wall, concrete wall or iron fence). The pulse host is also usually outdoors and transmits the alarm signal to the back-end control center through the signal transmission equipment. With the development of security technology, electronic fences will be built on the walls of some important places to prevent theft.

[0003] The existing electronic fence has poor alarm function. If criminals cut off the power cord of the electronic fence, climb the electronic fence, or dig a passage under the electronic fence to enter the other side of the electronic fence, the existing electronic fence cannot sound an alarm, so that the person in charge of the venue or nearby security personnel cannot be informed in time, which reduces the safety and anti-theft performance of the electronic fence. For this reason, we propose a new type of electronic fence. Utility Model Content
