Product Description

Combined with Rayleigh interferometric positioning technique and optical frequency domain scanning technique, the perimeter security system of optical fiber is analyzed by sensing the environmental stress of the optical fiber (cable) which is placed in the fortified area, or through the environmental stress of the carrier (such as overlying earth). The disturbance signal is transmitted to the main engine of the system, and through signal extraction, waveform analysis and intelligent behavior discrimination, the behaviors of breaking into the forbidden area are judged, and the system early warning and alarm can be realized, and the equipment such as video, acousto-optic and so on can be linked up. The real implementation of all-round, all-time intrusion monitoring.
