In today's not peaceful society, the sense of security is a very expensive luxury, but in the construction concept of "Peace China", the sense of security has never been absent.
In the fifth episode of the documentary "Brilliant China" Shared Xiaokang mentioned: "China has built the world's largest video surveillance network with more than 200 million video cameras. This large project called "China Skynet" is to protect the eyes of the people. "
20 million surveillance cameras are installed in the streets and alleys of China, and they sound amazing in numbers. While admiring the advanced technology, these thousands of "safety eyes" have also created a unique Chinese-style sense of security.
Chinese-style security: Let criminals have nowhere to hide
Recently, the high-profile anti-kill case in Kunshan came to an end with a "justified defense" case of innocence, and the result was a delightful one. But this is a great behind-the-scenes hero, video surveillance must occupy a place.
The police's video investigation at the scene of the crime showed that Liu Hailong, a man driving a BMW in the video, had a dispute with Yu Haiming, a man riding an electric bike. Liu Hailong took out a long knife from the car and slashed towards Yu Haiming. After a few knives, the long knife fell and was picked up by Yu Haiming and shot back to kill Liu Hailong. In other words, this is an incident of "BMW men hacked and killed."
It can be said that the clear video surveillance picture in the case has become the key to this case. Video surveillance perfectly restores the entire process of the case. "Seeing is believing" allowed the case to be solved quickly: Yu Haiming’s killing of Liu Hailong was a legitimate defense. No criminal responsibility. However, if there is no video surveillance, how will the outcome of the case develop?
Imagine that if there is no video surveillance, Yu Haiming must pay the price of killing Liu Hailong, because we have no way of knowing what happened at the scene of the crime, even if Yu Haiming argued that his anti-killing behavior was a positive defense, but because of lack Witnesses and the inability to restore the scene, how many people would believe his arguments? After all, Liu Hailong's death is a fact, and Yu Haiming's murder is also a fact. The police could not inquire about the motive of the murder.
Fortunately, the surveillance cameras recorded the entire process of the case, avoided an "unjust case" in the name of justice, and gave Yu Haiming a strong sense of security. However, this Chinese-style sense of security under the video surveillance system has long been commonplace.
Like the Kunshan anti-homicide case, the “June 29†female corpse case in Guangzhou University Town that received much attention in 2015 was also solved by video surveillance. The police handling the case revealed that the whole process of investigating the case relied on a video surveillance system. In addition to the video surveillance in the university city in the early stage, the trajectory of the victim’s activities on the day of the murder was found. In the later stage of the case, the police also investigated the surveillance video images of the bicycle hall to locate the suspect. Three days after the incident, the suspect was able to be arrested. Arrested and brought to justice.
In the eyes of Chinese people, the video surveillance system is a right-hand man in the case of breaking the case, bringing a strong sense of security to the people's life. And this sense of security is not only defended by the Chinese, but also by foreign friends who come to live in China. Foreign friends once joked: I am afraid that only China in the world dare to wear a miniskirt to the streets in the middle of the night. The 2016 Global Crime and Safety Index shows that China is one of the countries with the best public security protection. In the past five years, the number of China's eight types of serious violent crimes has fallen by 42.7%, and the sense of security has become China's new business card.
To put it in a hypocritical way, under the blessing of this three-dimensional public security social security prevention and control system, the sense of security that video surveillance brings to the people is that every ordinary person can be treated well, and every criminal has nowhere to escape. shape.
Science and technology support, a higher level of "Safe China" construction
The use of technology to make criminals have nowhere to hide is the Chinese-style sense of security brought by the video surveillance system. But with the blessing of higher science and technology such as artificial intelligence technology, this Chinese-style sense of security has brought a higher level of "Safe China" construction.
The current popular face recognition technology is a well-known example.
In the entire video surveillance process, based on the facial features of the person, the face recognition technology performs identity recognition on the input face image or video stream. When the face recognition technology recognizes that there are faces in the video, it further provides the position and size of each face and the position information of each main facial organ, and based on this information, further extracts the identity features contained in each face. And compare it with known faces to identify the identity of each face, thereby determining the identity of the face in each image or video stream. Today, this technology can also be combined with technologies such as pedestrian tracking and pedestrian recognition to be applied to fields such as intelligent video surveillance, human behavior analysis, and intelligent transportation.
The intelligent pedestrian red-light forensics system is online, allowing people to say no to "Chinese-style crossing the road"; the traffic flow monitoring system is available to empower smart transportation; Jacky Cheung’s concert completes the "eight kills", and the "fish that slipped through the net" is the past, let’s leave it for the time being It can be considered that, with the addition of surveillance cameras with facial recognition algorithms, the construction of "Safe China" ushered in a higher level and ushered in more possibilities.
Using artificial intelligence and big data to make police forecasts, video surveillance is not only popular in China, but also at the forefront of the world. Based on the rich practical experience of big data and coordinated case handling, Chinese public security has established the "strongest police brain", making video surveillance a "sharp weapon" for social security.
IDC stated in its latest "Global Smart City Expenditure Guide" that due to the increasing demand for video information sources that track citizens’ actions, fixed video surveillance will become China’s main source of expenditure, accounting for China’s total technology expenditure in 2018. 17.3%. With the blessing of artificial intelligence (AI) technology, China has deployed about 20 million security cameras to locate and track criminals. By 2020, China will complete the construction of facial recognition and surveillance networks nationwide, and conduct almost comprehensive surveillance of urban residents through smart phones and smart TVs.
The latest data shows that all parts of China are stepping up the deployment of city-wide surveillance: in 2020, video surveillance will cover West Security City, Liaoning video surveillance points will reach 1.1 million, Tianjin Expressway will achieve full video surveillance coverage, and implementation will be implemented by the end of Hubei. 4G dynamic video surveillance has full coverage, and Guangzhou Tianhe will build 1,400 video surveillance. Behind this city-wide surveillance, it not only reflects the power of the country, but also shows a higher level of "Safe China".
Perhaps the Chinese sense of security brought about by video surveillance cannot escape the issue of "privacy", but as netizens said, "you are not afraid of shadows when you are upright, and only those who want to do bad things will be afraid of video surveillance." What we can be sure of is that any time danger comes, video surveillance can become the technological support of "Safe China" and become the most powerful "brass wall and iron wall" for you and me.
"1.3 billion Chinese people have been completely caught by the camera, and every move is monitored in real time." Being monitored by video sounds like a horrible thing, but without video monitoring, an unordered life will be full of dangers and completely out of control!
Isn't this a worse thing?
