Civil air defense, as an important component of national defense, still plays a very important role in protecting the lives and safety of the people, avoiding or reducing national economic losses in peacetime. Recently, the large-scale HD-SDI digital high-definition matrix and audio-visual matrix of Kodi have successfully passed the acceptance of Haikou Civil Defense and have been officially put into use, providing a modern conference room with full digital control management for Haikou Civil Defense and providing a prerequisite for efficient work.

The Kodi Digital High Definition Matrix Series includes 3G-SDI Digital High Definition Matrix, HD-SDI Digital High Definition Matrix, and SD-SDI Digital Standard Definition Matrix, which comply with SMPTE and ITU standards. The SDI Matrix is compatible with serial digital signals of different bit rates such as 143Mbps~2.97Gbps. The automatic cable equalization function compensates for amplitude loss caused by long transmission distances from the video signal source to the matrix input. This series of matrices can adapt to uninterrupted working conditions of 7 × 24 hours, with an average time between failures exceeding 30000 hours, providing a stable and reliable signal transmission switching center for the system.

Kodi Analog Audio Video Matrix is suitable for various systems that switch audio and video signals. Its products include pure video matrix, pure audio matrix, and analog audio and video matrix. The matrix adopts two types of structures: modular plug-in board and solidified compact, mainly used in emergency command systems, monitoring centers, broadcasting and television systems, video and audio conference systems, audio-visual education and other industries for displaying multi-channel video and audio signals. Matrix size 4 × 1~512 × 512, using "field inverse" switching; Video supports high bandwidth output; Audio supports balanced/unbalanced input and output; Having an external synchronization signal interface; Supports multiple control methods including RS-232, RS-422, RS-485, and TCP/IP; All technical indicators have been tested by authoritative departments; All meet or exceed the Class A standard for broadcasting and television; Can adapt to uninterrupted working conditions of 7x24 hours; The average time between failures is greater than 30000 hours; Provide a stable and reliable signal transmission switching center for the system.

With the maturation of the industry and the widespread application of information technology, especially digital technology, Dalian Kedi continuously expands its professional skills, deeply understands customer needs, and continuously integrates new technologies into core solutions, achieving a new experience of intelligent office for users with the most focused attitude and sincere service.
