Long-distance monitoring solution with telephoto lens through fog - border and coastal defense, railway and forest fire prevention

Border and coastal defense is an inseparable and important part of national defense, and it is a necessary method for the country to effectively exercise sovereignty and maintain security. Border and coastal defense monitoring is a very important issue in military security. The traditional border and coastal defense monitoring (standing guard, lurking, and patrolling) that is suspended manually can no longer meet the needs of troop monitoring and military struggle. In order to complete the 24-hour discontinuous and barrier-free monitoring of border areas, border and coastal defense posts, unmanned border defense stations, unmanned islands, entry and exit ports, etc., the dynamic monitoring and monitoring system functions are used to compensate for satellite remote sensing and aerial mobile monitoring. If it is lacking, it provides all-day, all-weather, discontinuous information on the theoretical status and dynamic changes of border defense management for my country's border and coastal defense management, and completes the scientific, systematic, real-time and visualization of border defense management. 1. Ultra-long-distance monitoring range, ultra-clear monitoring effect Due to the work requirements of border and coastal defense, the monitoring system needs to complete the seamless monitoring of the entire border, and the monitoring scope of multiple monitoring points needs to be seamlessly connected; Monitoring systems and equipment must meet the three requirements of "fast, accurate and high-definition". 2. Can adapt to harsh working environment and has IR function For border and coastal defense applications, the monitoring front-end working environment is mostly very harsh, and it is exposed to wind and rain all year round. Therefore, the monitoring equipment used must have the ability to resist harsh environments. The monitoring point needs to be able to work normally in bad weather environment and be able to complete high-definition day and night monitoring. The monitoring point needs to be able to work normally in bad weather environment and be able to complete clear monitoring 24 hours a day and night. When designing the scheme, it is necessary to comprehensively consider the location and distance of the monitoring purpose, as well as the image effect of the monitoring purpose on the monitor. In applications such as border and coastal defense, railway and forest fire prevention, electric zoom lenses with large zoom and long focal lengths, such as 10-330mm, 20-750mm and 25-1500mm, are generally used. The front-end video acquisition system includes: multi-spectral high-definition fog-penetrating camera, high-precision digital pan/tilt with long focal length fog-penetrating lens, high-density protective cover, front-end control cabinet, lightning protection grounding, etc. This solution consists of a camera and a telephoto zoom lens number. The longest monitoring distance of the telephoto lens can reach 10 kilometers
