The significance of border and coastal defense is to safeguard national territorial sovereignty, ensure national defense security, and promote the modernization, technicalization and informatization of border and coastal defense management.

The border and coastal defense system can achieve 24-hour barrier-free monitoring of border areas, outposts, unmanned border stations, uninhabited islands, entry and exit ports, etc... Provide all-day, all-weather, uninterrupted information on the actual status and dynamic changes of border management, thereby enhancing security measures and ensuring that the country's territorial sovereignty is not violated.

The border and coastal defense system is also a powerful tool for the modernization, technicalization development and informatization of border management. By using advanced military technology and monitoring systems, such as infrared thermal imaging technology and high-definition fog-penetrating cameras, the system can achieve scientific, systematic, real-time and visual management of border and coastal defense areas, improve monitoring and response capabilities, and ensure that it can quickly attack and effectively respond to various security threats at critical moments.

The border and coastal defense system is mainly composed of three parts: front-end multi-sensors, mid-end transmission system and back-end display and control center.

Front-end multi-sensors: These sensors are usually installed at the commanding heights in border or coastal defense, and can obtain real-time telemetry data within the depth of the other side's border, including information on suspicious targets, border lines, duty posts, roads leading to the outside, border ports and other important locations. These sensors may include high-definition visible light cameras, infrared thermal imagers, low-light cameras, image sensors and other devices to achieve all-weather, all-round monitoring.
Mid-end transmission system: The transmission system is responsible for transmitting the data collected by the front-end sensors to the back-end display and control center in real time. This is usually achieved through optical fiber, wireless transmission and other means to ensure the stability and reliability of data transmission. In this way, relevant personnel can keep abreast of the dynamic changes in the border or coastal defense areas.

Back-end display and control center: The display and control center is the core part of the border and coastal defense system, responsible for receiving, processing and analyzing data transmitted by front-end sensors. Here, relevant personnel can watch the situation of the border or coastal defense area in real time through the monitor screen, and conduct command and control. The display and control center may also be equipped with advanced software systems and functional software to achieve the goals of real-time direct information and efficient command and control.

In conclusion, the defense system realizes all-weather, all-round monitoring and management of borders or coastal defense areas through the close cooperation of front-end multi-sensors, mid-end transmission systems and back-end display and control centers.
