the reported hearing yesterday, the city known as “wisdom eye” Wuhan city video surveillance system, successfully passed the expert acceptance; Wuhan City Mayor Tang Liangzhi personally pressed, the opening of the system, declared all over the city of 25 million video surveillance formal probe posts.
Wuhan city video surveillance system started construction in September 2009. Two years after construction, and finally succeeded by the academicians Li Deren, Zhao Zisen Academy of Engineering, an expert group composed of acceptance.
yesterday, city leaders Hu Xu Kun, Zhao Fei, Liu Liyong, attended the opening ceremony.
Wuhan 250000 probe into three categories. The first control point for the municipal, 5000, for covering the main city out of the city crossing, cross-river bridges, tunnels, major intersections and major parts, video surveillance is the backbone network, all construction has been completed, a total investment of 298 million yuan;
second category is the district-level monitoring points 20000, China Unicom used to cover the city’s main road and the important parts of the district; third category of social control points 225,000, according to a unified plan by the social unit from the building, its method of use and network “local storage, local calls, on-demand access.”
according to recently released “2011 Wuhan Geographic Information Blue Book “, as of 2010, the main city of Wuhan, the total area of ??493.76 square kilometers; 250 000 camera, the average per square kilometer of the” probe “number over 500, you can observe every move of the city’s most subtle, and many people have concerns about information leakage.
this, the public security authorities said that the entire system using fiber optic private network security, in the beginning of the construction is very security-conscious. In addition to ensuring safe and reliable system itself, video, information sharing, the implementation of tiered classification authority, strictly confidential to prevent threats to urban safety.

● Wuhan will be more safe
● tracing to find things more easily
● video tour of Wuhan is not a dream
set in the well-known attractions more than 80 probes, the signal will gradually Wuhan portal access, so that tourists can visit Wuhan on the Internet.
● provide travel suggestions
video monitoring can also provide the public with travel suggestions, the traffic control department has begun an attempt in this regard.
city “wisdom eye” system, there are many types of cameras.
– the most common ball-type, gun type camera: This most common type of camera usually set the ball in the street intersection, within a certain range of observation; gun-type camera mount is generally set , making the vehicle, license plate is a first-class knowledge.
– upgrades, integrated PTZ camera: This is a gun-camera mounted on a rotating head, due to gun-type camera can see up and down, head can be rotated 360 ° , the monitor a wider range, generally set in the tower side, can be “looked up” observing height situation.
– scenic, wide-angle panoramic camera: a necessary $ 30,000, a wide angle, panoramic rotation, video tours for visitors to Wuhan.
– setting the highest, most powerful camera: Hanyang Turtle Tower in the platform at 210 meters, three cameras facing in three directions. The camera, one should more than 20 million, through the fog function with 40 times zoom.

yesterday, the reporter to Wuhan Public Security Bureau to set the “Wuhan city video surveillance system” operation and maintenance center, field a glimpse of “wisdom eye” attractions.
full touch screen
like a big “IPAD”
into the operation and maintenance center, the most attractive sight is the middle of a podium. Standing around the stage, looking down on the table of the computer screen, showing the electronic map of Wuhan, which is an “electronic sand table.”
“This is a full touch-screen operation,” Municipal Public Security Bureau Deputy Director of ICT, Wang Wei, tap the screen, map zoom, the electronic eye of each point distribution at a glance, all the image with a only the red eye image representation.
Click on the map “eyes”, there have been the real point of the monitor screen, drag your finger around on the screen, just like turning the lens can be rotated 360 ° observation.
the whole operation, complete with finger clicks, multi-touch experience, as in the operation of a large IPAD.
According to reports, through the “electronic sand table” that allows decision-makers quickly and clearly see every place in Wuhan City, real-time monitoring screen, it can be said, standing in the monitoring center, you can always touch the city corner of the perception of social dynamics.
definition comparable to television broadcast
bad will “take the initiative to report”
click the e- map of the “eye” can see the real video. Reporters saw these images are very clear, “Some monitoring probe transmission clarity of the screen, even to the TV broadcast standards.”
Interestingly, the electronic map, there are some “eyes” are closed, and “This represents the electronic eye here is not running, the system is very clever,” is introduced Wang Wei with a smile.
this is reflected in the system and a leading technology – Automatic operation and maintenance, failure alarm monitoring probe will not only be on the electronic map display, but also through the operation and maintenance center background to determine the cause of the malfunction, automatic operation and maintenance departments to submit maintenance instructions, “if not repaired within a specified time, the system will automatically assess a point deduction.”
system can automatically alert
monitoring probes are so many, by manual monitoring? No, the system can automatically detect problems.
staff will monitor screen in front of government agencies to bring up an example, “If there is a car on fire, smoke was visible, the system will alarm.” In addition, by setting, where the monitor screen inside the left if there is an unknown object, and even vehicles, pedestrians passing faster than normal, the system will alarm.
addition to security, the system has been more progress on police intelligence. Reporters saw the use of “out of the police analysis” function, the police point of departure to the alarm, you can quickly adjust the camera to see along the way, select the most open route quickly arrived.
use of “rounding up analysis” feature, once a certain point in the event of a sudden cases, the police rounded up as long as the set area, the entire area of ??the camera all tune out, the suspect, the car as long as the road appeared, escape “watching.”
come to learn
According to reports, the entire system, its layout, network, operation and maintenance and other aspects of both innovation and similar cities in the country in the lead. In the experimental stage, there Chongqing, Shanghai, Zhengzhou, Xi’an and other cities come to study.
“general monitoring system, are formed in a small range of the system, but done in Wuhan city can be integrated into the monitoring system,” the staff, with technical terms that it is the first metro-level all-digital control system, even in the world are rare.
other words, through the authorization of any access to the city’s population, can enter the system, the video information for viewing, access to; in the past, the probe must be installed to monitor the place before the transfer video data.
In addition, the system uses a specially designed fiber optic network construction of public security, all-digital, also in the past the city has conducted a probe of analog video and digital network upgrade. It can be said, the city video surveillance system despite a late start, but the starting point is very high, directly into the country’s top level.
In addition, Wuhan has also put forward the innovation, “circles, blocks, grid, point” of the layout model.
Simply put, in Wuhan City 29 monitoring points set out crossing to form a closed “ring”; in 11 cross-river bridge and a tunnel across the river to set control points, the city is divided into Hankou , Hanyang, Wuchang three “block”; set up monitoring points in the main road intersection, forming a number of network “grid”; in important public places, schools, hospitals and other key parts of the set control “point” to achieve all-round monitoring. Also part of the patrol police mobile camera installed on the probe.
way, if someone committing the crime, even dodging the camera, making less than the incident, but as long as the person has a path of action, we will be able to find him and lock him.
