Safe City

Safe City definition of rehabilitation programs

1、Existing analog video surveillance systems

2、Hybrid video surveillance system after transformation

3、An Introduction
The program uses the South Tianwei visual development NTW-900 series SD / HD video mixing Optical, around already built analog video cameras, increase network HD cameras, using the original fiber, realize & ldquo; Safe City & rdquo; & mdash; & mdash; social security video surveillance system intensive, digital, high definition。
The program fully retain the original analog cameras, fiber, matrix and DVR and other analog video surveillance system equipment, maximize the use of existing resources on the basis of simply replacing the original analog video optical transceiver to SD / HD video mixing Optical, and laid in the vicinity of a small number of short-distance fiber optic analog camera, you can connect an analog camera around 1 to 8 additional remote access devices, each remote access devices can be connected to eight network HD cameras. SD / HD video Optical has eight optical ports and 1 to 4 BNC interface, the received optical signal and analog video signals via an optical fiber core original transmission to the monitoring sub-centers or police stations. In the center-side configuration standard / HD decoding matrix box, can be implemented on the same piece of screen, high-definition display, SD compression, uncompressed video display and other formats。
The program to maximize the use of existing equipment and fiber resources, reducing the new fiber, simplifying the construction difficulty, reducing construction costs, especially for & ldquo; encrypt existing analog monitoring points, enhance video surveillance clarity & rdquo; the occasion。

4、Program benefits:
Retain the existing analog cameras, fiber, matrix, DVR and other equipment, to maximize the use of existing equipment;
Without re-laying of fiber optic trunk line, simplifying the construction difficulty, reduce the construction cost;
Optical network connection definition cameras nearby, all-optical interconnection, a core fiber upload, easy construction;
On one fiber hybrid transmission of uncompressed analog video and network HD video, saving fiber resources;
Each screen can display an HD, SD and compressed, uncompressed video;
Analog video, online video unified mode of operation, ease of operation to master;
