An Electronic Fenceis an intelligent perimeter protection system composed of a pulse generator (host), a front-end fence and related control equipment. After years of evolution and improvement, modern public-safety Electronic Fences have become a new, mature perimeter alarm product. It breaks away from the traditional post-event alarm model of perimeter protection and emphasizes a new perimeter security concept centered on blocking (a physical fence that creates an intrusion barrier) with alarm (audible and visual alarm, linkable with other security systems) as a supplement, plus deterrence (reducing criminal intent). Compared with Infrared Beam Detectors, it offers lower false-alarm rates, stronger deterrence and active protection, and most importantly it is easy to link the anti-theft alarm with the surveillance system. These advantages favor the application of Electronic Fences in the important power sector.
From this perspective, as a more advanced product than Infrared Beam Detectors, the Electronic Fence better meets the protection needs of power plants and unattended substations. So from a security professional's perspective, what problems with Electronic Fences restrict their application in the power system?
High cost hinders the popularization of Electronic Fences to some extent. Mr. Liu Dongming of the Beier China Power Marketing Center once mentioned that the power industry's investment in monitoring systems is fixed. In fact, this also matches the market situation of Electronic Fences, but Electronic Fences cost more than Infrared Beam Detectors, so their popularization in first- and second-tier cities is just around the corner. However, many substations are located in remote areas; although substations have government subsidies, the product characteristics reduce business opportunities for Electronic Fence companies to some extent. Currently, the Electronic Fence can be regarded as a relatively mature perimeter alarm product with a long service cycle. When market demand becomes saturated, Electronic Fence suppliers will inevitably have fewer business opportunities; from this perspective, the Electronic Fence market is perhaps one where buyers rejoice and sellers worry.
Mandatory government implementation will accelerate market promotion. After Shanghai's "Document No. 12" was issued, Electronic Fences were widely used in Shanghai communities under the "mandatory" requirement. Although power applications are not within the mandatory installation scope, the installation of Electronic Fences in the power field can also be regarded as standard. The successful application of Electronic Fences in Shanghai communities will accelerate their promotion in the power system. But if negative cases appear, they will also affect promotion, and the market needs all manufacturers to cultivate it together.
As a protective barrier in the power field, the Electronic Fence protects facilities while safeguarding our normal life and social stability. Due to the technical advantages and application prospects of Electronic Fences in the power field, before newer anti-theft alarm technologies emerge, there is bound to be broad room for development.
