Description

Technical Field

[0001] The present invention relates to the technical field of intelligent monitoring equipment, and in particular to a wide-area intelligent monitoring equipment using a medium- and long-focus camera matrix. Background Art

[0002] The wide-area intelligent monitoring equipment of the medium- and long-focus camera matrix is ​​a high-precision monitoring system that combines optical technology, AI analysis, and multi-sensor collaboration. It is mainly used for real-time monitoring, target tracking, and intelligent analysis of large-scale scenes. The medium- and long-focus lens matrix consists of multiple medium- and long-focus lenses, covering medium and long distances, supporting optical zoom and autofocus to ensure clear long-distance images. The CNC platform transmits real-time data and issues alarms for on-site conditions. This type of wide-area intelligent monitoring equipment effectively reduces manual inspection costs by about 60%, and is widely used in existing border inspections.

[0003] Most existing wide-area intelligent surveillance devices use fixed cameras installed at specific locations to monitor borders. This setup only monitors the area covered by the installation point. Even wide-area devices still have blind spots in actual use. Furthermore, existing wide-area intelligent surveillance devices that use a matrix of medium- and long-focus cameras cannot adaptively adjust the height and angle of the surveillance device when there are obstructions along the surveillance route, resulting in a lack of timely monitoring of border conditions. Therefore, we propose a wide-area intelligent surveillance device that uses a matrix of medium- and long-focus cameras. Summary of the Invention
