With the development of economy and the acceleration of urban construction, the population density and floating population increase in cities have caused urban management problems such as traffic, social security and prevention of key areas in urban construction. Especially in the face of the new issues of urban anti-terrorism in recent years, the public security management, especially the crime prevention and law enforcement work put forward new challenges. However, the increase of the police force is far from meeting the development speed of the actual demand, so the urban security image monitoring which can transform scientific and technological means into direct combat effectiveness has become an important means to solve the problem. Under the promotion of the city security environment, the safe city wireless video surveillance system emerges at the historic moment.
Safe City wireless video surveillance system needs to integrate public security and social alarm and monitoring resources, strengthen the security measures in the process of information generation, storage, transmission and processing, and realize the sharing of alarm and image information by public security organs and relevant government departments. And the overall system design and equipment selection and matching, should have the advanced level at home and abroad, not only need reliable quality, stable performance, long service life, but also need to have a strong system expansion margin and telecommunication networking ability.
The wireless video surveillance system of Safe City usually consists of the following three parts:
Ⅰ. Front-end acquisition part
The front-end collection section is generally set up by local police stations to monitor alarm monitoring equipment such as road sections, residential communities, office buildings and schools in the local area.
Ⅱ.the middle transmission part
The middle transmission part is mainly set up in the upper level of the front monitoring department, which can be the alarm monitoring center of the public security branch. The mid-end monitoring system converges the front-end points to each trunk building based on the actual site conditions. The middle monitoring system mainly manages front-end monitoring, and can also directly receive the alarm monitoring equipment of the local area, and manage it in a unified way with the front-end monitoring center.
Ⅲ. Back-end monitoring center
Back-end monitoring center The highest level of the city's monitoring and command center, generally set up in the city level alarm monitoring center. The monitoring center at this level has the highest permission for city monitoring and can directly monitor and manage monitoring devices in the front-end, mid-range, and local areas. As the primary monitoring center is the highest center of urban monitoring, this level needs not only capacity, but also high security and powerful expansion ability.
Suntor Safe city wireless video monitoring system is designed for urban traffic safety, environmental protection monitoring, urban anti-terrorism, emergency search and rescue, crowd illegal assembly, fire warning, natural disaster monitoring needs, including video signal acquisition, transmission, identification and integration with the dispatch command system key link, high intelligence, real-time. The system adheres to the construction principles of advanced nature, practicability, reliability, economy, integrability and expansibility. It is a very practical monitoring system in the construction of safe city.
