SmarterFence from Smarter Security is a fiber optic security fence that intelligently detects and warns of intruders while minimizing nuisance alarms. The fence employs a continuously monitored and intrinsically safe fiber optic sensor cable that is sensitive to a wide range of vibrations, flexing, compression and cutting. The motion detector relies on the transmission of laser light as its communication medium so it does not radiate signals nor is it susceptible to electromagnetic interference. The system provides cost-effective protection for zones up to 3,000 linear feet in length, and it can be combined with other outdoor security measures to maximize protection.
