iii、System Structure
1.Key areas monitoring
For key areas, such as banks,stations,intersections, government agencies, residential area, etc., require continuous monitoring round the clock. For areas which environment illumination is dark at night, can choose the laser night vision products with imaging distance 200 ~ 400 meters at night and 500 ~ 800 meters in the daytime.Low price with high intelligentize degree,such products can monitor at multiple spots and form an effective video surveillance coverage.
2.High altitude outlook
City outlook system refers to the Pan-tilt camera and video monitoring system with the matched transmission, display and control quipments which are installed within 30 ~ 100 meters,or even more than 100 meters off the ground in the city, in order to realize the real-time video surveillance within the scope of a few kilometres away.
City outlook system is an important part of "safe city" construction, and it has important significance for the city monitoring on fire,focus objectives,public security,forest fire,airport perimeter security, air defense security,border defense & environmental protection and so on.
3.Vehicle-mounted mobile monitoring system
4.Transmission and display
The monitoring points will transfer the collected video to monitoring sub-center and center through optical fiber and Ehernet switches in a real time.The communication computer in monitoring sub-center and center will display, processing, output, and storage all kinds of informations within the LAN and realize the sharing of informations and datas or the managing according to privilege.
The front-end monitoring subsystems all adopt network transmission, which means transmitting the front-end video,audio and alarm information to first grade monitoring center by ADSL, CDMA, microwave, 3G, optical fiber and partial wideband.
iv、Typical case
■ 24h-Safe City project in Europe
■ Security dynamic monitoring project in South Africa
■ Vehicle-mounted mobile monitoring project in USA
