The Importance of Subway Security System
Monitoring system, security inspection system, access control system, and intelligent video analysis. The video surveillance system is the core part, accounting for 50%-60%, the security inspection system accounts for 30%-40%, and the anti-theft alarm system is relatively few. From the perspective of demand, the share of security x-ray baggage scanner, explosive detection, and toxic gas detection will increase. With the development of technology and the actual needs of subway security, it will be gradually upgraded in the near future.
The subway operates in a relatively small and enclosed underground space, where people are densely populated and vulnerable to attack and destroy. With the increasing demand for subway security inspection construction, the number of the x-ray machine, baggage screening scanner, doorframe metal detector, the explosive detector has doubled, and it is useful for the security staffs to find problems under the help of these inspection devices. Intelligence is a constant demand in the world. At present, subway safety management has evolved from passive after-the-fact remediation to more proactive predictive safety management methods. The use of intelligent video analysis technology to achieve early warning and prevention. The security technology is developing very rapidly.
The proportion of the entire subway construction and operating costs are not very high, but when it comes to extreme events, the role played is very important. As an emerging industry with great growth in the national economy, the security industry is developing rapidly, and the demand for security products in various industries is increasing, such as x-ray baggage scanner, walk through metal detector, explosive detector, etc. It is reported that 33 cities in China are planning to build subways, and 28 cities have been approved. Metro security will become another hot spot in the security industry.
