The project site is a storage and transportation terminal of finished petrochemical products. It’s one of the largest import and export ports of liquefied products in China and it’s also the only bonded logistics center with liquefied products as main business line in China. It belongs to inflammable and explosive area and the total length of its perimeter is 4.8km, so perimeter protection is the focus of this project. The scheme needs to give special consideration to the influence of special marine climate of coastal terminal on perimeter environment. The third-generation environmental adaptive and analysis technology built in the system addresses this issue properly and solves the issue of accuracy rate and false alarm rate of fiber optic perimeter alarm thoroughly. After installation and debugging on site, the operation of the system is highly praised by the engineering integrator and security department of the user.
