Smart Residential Community Security Solution

             Solution overview:

            In recent years, with the large influx of migrant population, the urban population is characterized by a large base, high mobility, scattered residential locations and high management difficulty. The resulting public-security, criminal and other social problems have also shown a year-on-year upward trend, posing huge tests and challenges for people living and working in peace, comprehensive urban governance, and the police "strike, prevent, manage and control" work. At the same time, demands at the community level for handling new types of cases are becoming increasingly urgent. It is therefore necessary to build an intelligent, three-dimensional community security and prevention system to improve community security governance and, in turn, comprehensive urban management capacity.

1. General Overview

　　In recent years, with the large influx of migrant population, the urban population is characterized by a large base, high mobility, scattered residential locations and high management difficulty. The resulting public-security, criminal and other social problems have also shown a year-on-year upward trend, posing huge tests and challenges for people living and working in peace, comprehensive urban governance, and the police "strike, prevent, manage and control" work. At the same time, demands at the community level for handling new types of cases are becoming increasingly urgent. It is therefore necessary to build an intelligent, three-dimensional community security and prevention system to improve community security governance and, in turn, comprehensive urban management capacity.

　　Following the design philosophy of "unified planning, unified standards, unified platform and unified management", the Smart Community Security System achieves comprehensive awareness of community data and events through video surveillance, micro checkpoints, facial-access doors and various IoT sensing devices within the community. By fully applying new technologies such as big data, artificial intelligence and the Internet of Things, it builds a "Smart Security Community System" centered on intelligent big-data applications, forming a three-dimensional community prevention and control system jointly built by the police, comprehensive governance authorities, sub-districts and property management. It effectively improves the management of special populations, persons of focus, persons involved in cases and other target groups, continuously enhancing the forecasting, early-warning, analysis, precision strike and dynamic management capabilities of government agencies such as the police and comprehensive governance authorities, raising the intelligence level of community prevention and control and improving residents' happiness index.
