Ten households joint defense alarm system solution

1. Social status

With the deepening of the new rural construction, the people's life is getting richer and richer, but there are always some people who are willing to work hard and want to get it for nothing, the various social contradictions are more prominent, and the situation of rural social security is becoming more severe.
However, despite the continuous development of the countryside, the improvement of the material foundation has not brought about the corresponding increase in soft power. Compared with the cities, the countryside has no skynet and no large amount of police protection; how to alleviate this contradiction and solve the farmers' safety precautions The need is urgent!

1-1. Construction requirements

The construction of a safety project for rural households is not only a requirement for public security prevention and control in rural society, but also a need for public security agencies to combat theft and crimes, establish a comprehensive public security prevention network, extract image clues and evidence from incident investigation, and demand for unified management of public security in various jurisdictions. .

1-2, the need for security

At present, villagers who are mainly engaged in crop production and poultry farming have become the targets of criminals. The weak status of rural public security often gives criminals the opportunity to take advantage of them. The peasant masses have poor awareness of prevention, and many families left behind elderly and children are unable to prevent it; therefore, it is urgent to strengthen the construction of public security monitoring systems and anti-theft alarm systems, install monitoring systems at the main entrances and exits of villages, improve public security, and effectively achieve mass defense groups. Governance effect.

1-3, the need for family property security

The peasants struggled all their lives to have a decent home, and devoted all their efforts to the home. Due to the weak grass-roots infrastructure in the rural areas, the large number of people in the rural areas, the small number of police officers in township police stations, insufficient police force, and unable to take care of every corner of the countryside; therefore, it is urgent to strengthen the establishment of a ten-unit joint defense alarm system for rural households and establish villagers The home is directly connected with the police station. If a thief breaks in to trigger the alarm device, the system will upload the alarm information to the police station's receiving platform within 15 seconds, and use the limited police force of the township police station on the blade.

1-4. Needs of the lonely elderly, left-behind elderly, and children

With the development of economy and technological advancement, rural farming and breeding have been unable to meet the surplus labor force. A large part of the rural young and middle-aged labor force has gone out to work, forming the only "left-behind family" currently in China. Most of the elderly and children remain in In rural areas, when their families need the most care, the "sons and dads" are far away from him, thinking that the biggest function of all ten households' joint defense lies in "difficult families and ten-party support", which maximizes the Chinese people's mutual assistance and love. A distant relative is worse than a close neighbor. Minimize unnecessary injuries. Let relatives who are far away from home work with peace of mind. Don't let these young people who are struggling for home and country construction sweat, shed blood and cry, and provide warm service to the rural people.

1-5. Demands for investigating and cracking down on crime

Public security surveillance provides first-hand evidence for the police to solve the case. Earn time for solving cases.

1-6. The need for unified management planning

Due to the large area and large population in rural areas, the existing police forces deployed by village committees are far from meeting the needs of rural public security. Strengthen the construction of security and anti-theft systems and monitoring systems in rural society. Through the combination of "civil defense + technical defense", achieve unified management and planning of the areas under its jurisdiction, improve the level of local social security, and crack down on illegal and criminal acts. "Pre-alarms are prevented, people are prevented during incidents, and evidence is monitored afterwards." We are working hard to build a "safe village".

1-7.Summary

In summary, in order to prevent and deter crimes, reduce the loss of farmers' property, protect the personal safety of farmers, improve the national security system, improve the overall security control ability, and create a civilized, safe, harmonious, and beautiful rural environment. A 10-unit joint alarm system suitable for rural security protection is needed. This system links farmers, protects and manages groups, and has difficulties for the family. The ten parties support it.
