physical protection
Environmental security is a very important part of the security system, including the protection of private places such as residential areas, construction sites and industrial plants to prevent illegal intrusion, as well as the protection of national borders, major airports, military bases, and so on. Reliable and expected protection must be provided, which requires a high-sensitivity detector and timely transmission of hazardous signals.
An environmental security system based on DAS fiber optic sound technology is currently the ideal solution. Compared with traditional infrared, electronic fences, lasers and other security systems. Fiber optic sensing systems are very sensitive to pressure and vibration, and have two functions of sensing and signal transmission, the possibility of real-time monitoring of disturbances
They give different to the fiber and change the part. Vibration into an electrical signal and its transmission to the processing unit for analysis and detection, and the realization of an alarm for the influence behavior in the monitoring area.
In addition, the distributed optical fiber sensing system is an all-fiber system resistant to anti-electromagnetic interference, corrosion resistance, the ability to operate at high and very low temperatures, easy installation and easy maintenance that can meet the requirements of intrusion detection in harsh environments. And meet the complex.
