As one of the largest countries in South America and one of the BRICS countries with a population of over 200 million, Brazil has experienced a certain degree of economic growth in recent years, but social security has been criticized. The security environment in large and medium-sized cities such as Rio de Janeiro and São Paulo is clearly unable to keep up with the trend of economic development. Therefore, Brazilian government agencies, residential buildings and various commercial facilities began to install and use security equipment such as video surveillance and access control on a large scale, which led to the rapid development of the Brazilian security industry and the huge demand for security products.

At present, more than 70% of Brazil's security products are still dependent on imports, so the Brazilian market has also been an important part of the domestic security enterprise layout over the years. At present, video surveillance equipment such as Chinese companies, biometric access control devices, closed-circuit television, alarm systems and vehicle monitoring systems are all local security products.

It is undeniable that the Brazilian government has indeed put in a lot of efforts in this year's Olympic security direction: the security personnel of this year's Brazil Olympics will reach 88,000, double the London Olympics. Rio's surveillance cameras have increased from 3,500 at the beginning of the year to 6,200 now, and the number has almost doubled.

In addition to the new use of drone monitoring, baggage cargo scanners, wireless intercom and other security equipment, in this Olympic Games, we can also see a new security technology: some exquisite live images of the Olympic Games Manual shooting will no longer be used, but will be done by the on-site monitoring equipment and the shooting robot.

The smart cameras arranged in all corners of the stadium provide a richer operating option for the live camera directly. In some games, even remote control cameras can be operated for 360° omnidirectional shooting.

When the athletes are on the court, the cameraman can control the camera to capture a specific picture through the software on the tablet or laptop. It can also facilitate the operation by presetting the camera's shooting angle and mode, which greatly facilitates the operation. The work of the cameraman.

Then why is the security work of the Brazilian Olympic Games still being criticized by all parties? The author believes that: to create a modern security system, civil air defense, physical defense, and technical defense are indispensable. Although the Brazilian Olympic Games invested a lot of money in security work, it did not effectively combine the three. Many security equipments have powerful functions and have not been used in practice. This is ultimately the result of the Brazilian Olympic security system not playing its full role. The root cause.

As a global sports event and cultural event, the Olympic Games requires a high level of security to ensure its safety. However, the security problems of previous Olympic Games have caused great headaches for every country. In fact, the security system of the Olympic Games is undoubtedly a concentrated performance of a country's high-tech, rapid response and comprehensive quality of the people.

It is also a big stage for the host country to fully demonstrate the comprehensive national strength to the people of the world. The host city does not want to see the big accident.

Below we take a look at the security measures of the host countries.

2012 London Olympics

The Secretary of State for Security and Counter-Terrorism in the United Kingdom, Ms. Neville-Jones, said: "Since the UK is fortunate enough to win the right to host the 2012 Olympic Games, we have made safety and security issues a top priority in the country." Said, it is indeed so hard.

In order to ensure the smooth running of the Olympic Games, the British government established the Olympics organization guarantee mechanism and formulated the "2012 Summer Olympics and Paralympic Security Strategy". Under the guidance of this strategy, the British forces actively participated in the London Olympics security operations: the London Police Department established the National Olympic Coordination Center, the London Fire Department, the police station, the emergency center and the military and other relevant departments jointly formulated the response to the Olympics. The joint action plan for emergencies during the construction of the project involves a large number of information technology applications.

In the event of an emergency, the on-site fire safety team will immediately report to the London Fire Department Command Center, and the command center will promptly mobilize the corresponding rescue force to rush to the scene according to the type and scale of the disaster.

2008 Beijing Olympic Games

The security technology system of the 2008 Beijing Olympic Games mainly includes peripheral alarms, automatic vehicle identification detection, portrait comparison and positioning technology equipment, and established six security technology subsystems including computer information application command system. Among them, the face measurement technology has never been used in previous Olympic Games, even those who have been completely accepted can be accurately identified.

At the same time, Beijing established a traffic guidance system in line with international standards in 2008, and implemented seamless TV monitoring for all Olympic traffic roads.

In addition to the use of unprecedented high-tech means, the Beijing Olympics security department has also established the concept of “closed zone”, which stipulates that there are guardrail enclosures around the perimeter, physical isolation facilities from the outside world, search and explosion inspection before use, and closed management in use. There are special forces to carry out documents and security checks on entering personnel and vehicles.

2004 Athens Olympics

International Olympic Committee President Rogge once commented that the Athens Olympic Games was held in a safe and secure way. The safety work of the Olympic Games is the largest and most internationally coordinated defense operation in history. It focuses on cooperation with different countries in security planning, security drills, security training and intelligence cooperation:

First, a large number of security personnel were trained in various forms, such as sending security personnel to study abroad, and teaching foreign teachers to teach in the country.

The second is to hire an independent security consultant who once served in the Sydney and Salt Lake City Olympics, and hired a security operation officer who was a member of the Sydney Olympic Organizing Committee. Greek national experts also participated in the Sydney and Salt Lake City Olympic Games.

The third is to establish an Olympic advisory group composed of experts from Australia, France, Germany, Israel, Spain, the United Kingdom and the United States with extensive experience in the safety planning of large-scale sports activities.

Fourth, in the intelligence cooperation, relying on the intelligence agencies of 21 countries including China, a global security intelligence information network was established. The International Atomic Energy Agency, Interpol, etc. also extended a helping hand to Greece.

Former President of the International Olympic Committee, Jacques? Rogge previously said: "If there is no application of information technology, the Olympic Games will not be successfully held." Throughout the Olympic Games, information network technology has played an increasingly important role, especially after entering the 21st century, information network technology has become more It is the beginning of the Olympic Games.

How to ensure the safety of the use and operation of Olympic venues, how to deal with emergencies relying on the urban emergency system during the Olympic Games, how to ease urban traffic, and ensure smooth roads are all for the world's attention, and thus promoted The wide application of information and communication technology in large-scale events.
