Security News With the extensive and in-depth development of big data, the Internet of Things, and the mobile Internet, everyone is no stranger to the current hot and peaceful city construction. With the construction of smart cities that people have been pursuing in recent years, Pingan City will eventually move closer to smart cities. However, in the face of terrorist violence incidents, the city of Ping An is a hit, and everyone is pondering over the construction of a peaceful city that is currently in full swing, and how safe cities can be constructed to increase the success rate of prior detection, thus alerting them to contain such incidents. happened. How can we effectively use the nationwide video surveillance system? How can we achieve network surveillance and control of video surveillance equipment across the country? How can we catch the criminals at large?

The weakness and lack of security systems have caused people to question the safety of the city. What role can the peaceful cities that are currently in full swing play in the face of a wide range of riots?

Video surveillance system into life

The video surveillance system has entered people's lives since the 1970s, and has gradually grown and improved through the three stages of analog surveillance, digital surveillance, and network surveillance. However, due to the influence of the classic monitoring model, most of the active video surveillance systems mainly focus on real-time surveillance and video retrieval, and the core of anti-terrorism and anti-terrorism is the 'prewarning and prevention of the aftermath', especially the first two steps: early warning and prevention. It is even more important. This is not possible with traditional video surveillance systems based on passive recording and post-examination. There is a fundamental difference from the active prevention and control of anti-terrorism requirements.

The role of intelligent video surveillance technology

After the violent violent terrorist case of Kunming Railway Station 3.01 occurred, some media used 'unexpected signs, and the Kunming Railway Station was baptized' to describe the sudden and tragic events when the case occurred. As a Chinese, the feeling of anger and grief over seeing such news cannot be expressed. Although we are unwilling, we must accept that the terrorist activities will exist for a long time, that terrorist destruction has been normalized, and that the pressure of counter-terrorism in the Mainland has increased. The monitoring system needs intelligent analysis technology to enhance its early warning and prevention effectiveness in the event of a terrorist case. Let the home security leading brand 'Harmony Guardian' R&D engineers give us an analysis of what intelligent video technology can bring us:

1. Face capture

In the video that satisfies the video analysis conditions, the face appears in the locked scene and the face capture is completed.

2. Face detection

Through binocular stereo vision technology to achieve the extraction of human attributes, such as gender, age, height, wearing glasses, whether it has typical national characteristics. 3. Face matching

Compares the captured face with the concerned person database for blacklisted faces, such as terrorist suspects and fugitives, and performs real-time alarms according to the set accompaniment threshold.

4. Monomer and population behavior detection

In the video that satisfies the intelligent video analysis, it automatically discovers the behavior of running, sudden personnel gathering, sudden scattering, etc., and performs real-time alarm according to the set rules.

5. Vehicle Inspection

In the video that satisfies the intelligent video analysis, capture the vehicle picture and extract the characteristic attributes of the vehicle, such as license plate number, license plate color, vehicle body color, vehicle model, vehicle logo and so on.

6. Pay attention to station security monitoring to protect the safety of the station

The construction of the station security system is centered on video surveillance and is diverging around. Among them, closed-circuit television monitoring system mainly includes operating closed-circuit television monitoring, ticketing closed-circuit television monitoring and public security video surveillance system. Operational CCTV monitoring systems are generally used by operators and managers to monitor station passenger flow, trains entering and exiting stations, and passengers getting on and off the train in real time. This is an important means to enhance the operation and management of the organization, improve efficiency, and ensure the safe and on-time delivery of passengers. Many violent and terror incidents are premeditated and even prognostic. If they can be found in a timely manner in the crowd, losses will be reduced to a great extent. Using cloud smart cameras, real-time monitoring of all regions.

Compared with traditional cameras, smart monitoring can completely detect whether someone is in some key areas or is doing some over-excited actions. For example, when a knife is pulled, it automatically recognizes and alarms, and locks the suspect to focus on shooting. At this time, alarm information can be sent to the general public in the region to remind them to evacuation to a safe place in time, and some emergency exits and exits are automatically opened to speed up the evacuation activities. The security personnel will also be fully armed to control those people. Criminals. It is not too late to remedy the situation. The key to the construction of the Safe City (Intelligent Video Surveillance System) is to establish an effective counter-terrorism and security system, strengthen security forces, increase the speed of reflection, and perpetuate the protection of people's lives.
