Nanning police build "four levels of prevention and control"
On May 26th, the Nanning Public Security Bureau Patrol Detachment carried out the “Harmonious Campus, Science and Technology Escort†activity in the 21st Middle School in Nanning to strengthen the campus security system and respond to the recent frequent school violence and terrorist attacks.
On the morning of the same day, the Nanning Police and the school’s security department jointly conducted a campus anti-terrorism and anti-riot drill. During this period, the police used the improved campus defense technology of the police to effectively crack down on various violent behaviors of lawless elements. In addition, the police also organized students to observe the school’s students. The use of police equipment and anti-riot equipment will increase the riot awareness of middle school students.
Because the school is located in the suburban area, the surrounding environment of the school is complex, and there are many idle workers. The safety hazards are high. The Nanning Police has purposely created a “four-level prevention and control†video system, which is based on the school’s original single video surveillance. , Batches are established in the “four-level prevention and control system for school gates, key areas in schools, dormitories and temporary monitoring areas, school security departments equipped with *****â€, and the video surveillance system is connected to the Public Security Bureau Pingan Nanning network monitoring system .
The monitoring system also installed "identification" and "one-click" alarms, that is, the system reads through the second-generation ID cards to quickly identify whether the entry personnel are suspicious and use color prompts to judge. Whether it touches the “one-click†alarm button connected to the command center of the Municipal Public Security Bureau, these measures ensure that the police can timely prevent, detect and deal with violent incidents on campus.
