Smart City Security Monitoring Solution

I. System Architecture and Technical Support

Multi-level Networking Architecture

• Establishment of Three-level Monitoring Centers: Create city-level, district-level, and police station-level monitoring centers. Achieve cross-regional coordinated management through the video surveillance system. For example, the city-level platform integrates data from the entire city, the district-level platform is responsible for regional scheduling, and the police station-level platform implements localized monitoring.

Intelligent Sensing Technology

• High-definition Cameras: Cover key intersections, shopping malls, and other areas. Support functions such as face capture and behavior analysis (such as crowd gathering and line crossing detection).

• Internet of Things (IoT) Devices: Integrate data such as vehicle recognition and environmental monitoring to enhance risk warning capabilities.

• Pan-tilt Control: 360° rotating pan-tilts with explosion-proof and waterproof designs to adapt to complex environments.

Big Data and AI Applications

• "Big Data + Cloud" Platform: Integrate massive video data through the "big data + cloud" platform to achieve intelligent applications such as crime prediction and traffic guidance. For example, analyze real-time traffic data to optimize traffic lights and alleviate congestion.

II. Core Functional Modules

Real-time Monitoring and Early Warning

• 24/7 Monitoring: Support 24-hour monitoring of public places and transportation arteries. Automatically recognize abnormal behaviors (such as fighting and theft) and trigger alarms.

• Vehicle Tracking System: Combine with GPS vehicle tracking systems to quickly locate and apprehend traffic fugitives.

Data Storage and Management

• Network Video Recorder (NVR) Storage: Use NVR for storage and support RAID redundancy technology to ensure data security.

• Unified Database: Establish a unified database to integrate information resources from public security, fire protection, transportation, and other departments.

Intelligent Operation and Maintenance System

• Device Status Monitoring: Monitor device status (such as defocusing and occlusion) through the operation and maintenance system and automatically repair faults.

• Automatic Equipment Inspection: Support automatic equipment inspection to reduce manual maintenance costs.

III. Construction and Implementation Key Points

Equipment Selection and Layout

• High-definition Network Cameras: Cover main roads with high-definition network cameras. Use 360° panoramic cameras for open areas such as squares.

• Wireless Transmission System: Suitable for suburban areas with insufficient fiber resources to reduce deployment costs.

Network and Platform Design

• IP-based Star Network Topology: Build an IP-based star network topology to ensure data transmission stability.

• Unified Management Platform: Develop a unified management platform to achieve cross-system data sharing and linkage (such as alarm and video image linkage).

Practical Application Optimization

• Intelligent Analysis Equipment Deployment: Deploy intelligent analysis equipment in areas with frequent cases to improve arrest efficiency.

• Integration of Social Resources: Integrate social resources (such as community surveillance) to form a "police-civilian joint defense" model.

IV. Challenges and Future Directions

Existing Problems

• Inconsistent Equipment Protocols: Difficulty in interconnecting different systems due to inconsistent equipment protocols.

• Data Storage and Analysis Capability: Need to further enhance data storage and analysis capabilities to cope with PB-level video data.

Development Trends

• Intelligent Upgrading: Deep integration of AI into security systems to achieve behavior prediction and precise deployment.

• Resilient City Construction: Strengthen emergency response and data security by combining blockchain technology.
