2, the system structure
3, system solutions
The 3.1 exam subsystem
The system the examination room for a total of 32 test sites, the front-end a total of 32 analog video surveillance into the back-end system, after internal video coaxial cable transmission. The backend configuration Engelhard, as video switching platform two local display, management and storage, and the analog video signal encoding packaged into networked digital video signal transmission through education to City Zhaoban monitoring center. Support for 16-channel analog video input and 16-channel network video input interface, spared for future expansion of the system fully prepared; the maximum support 5Tb local storage to ensure each examination room is kept for at least a month of 24-hour video data; configuration of a display, will be able to achieve the real-time monitoring of the local; both local management and component video switching platform group, through education special network unified municipal Admissions monitoring center management.
