Smarter Fence is specifically designed to provide reliable, early warning of intruders by detecting any attempt to cut, climb, or crawl under perimeter fences. Smarter Fence Sensor System consists of a processor module that transmits a laser beam through a fiber optic sensor cable that is sensitive to a wide range of vibration, flexing, compression, and cutting, while at the same time minimizing nuisance alarms from natural causes. Since Smarter Fence relies on light as the detection method, it is intrinsically safe as it does not radiate signals, nor is it susceptible to electrical interference. This makes it particularly suitable for use in hazardous industrial locations where there is risk of fire or explosion. Smarter Fence cable is very easy to install and field repair or replacement of a damaged section of cable is remarkably straightforward, using a simple but effective splice connector.
