The landslide and building tilt video monitoring system is a disaster warning and safety management platform based on AI visual recognition, sensor networks, Beidou positioning, drone inspection and other technologies. Its practical significance is reflected in multiple dimensions such as disaster prevention and mitigation, public safety protection, and urban sustainable development. Especially in the context of frequent extreme climate and accelerated urbanization, its value is becoming more and more prominent.

1.Safety protection: reduce loss of life and property
Landslide early warning and emergency response

Real-time monitoring: The camera captures data such as surface cracks, soil displacement, and rainfall changes, and combines it with synthetic aperture radar interferometry technology to achieve millimeter-level deformation monitoring (with an accuracy of 0.1mm/day).

Timeliness of warning: The system can issue a warning hours to weeks before a landslide occurs (for example, the system deployed in the Jiuzhaigou Scenic Area in Sichuan can issue a warning more than 30 minutes in advance), strive precious time for personnel evacuation.

Building security monitoring and reinforcement
Tilt warning: The tilt angle of the building is monitored in real time (accuracy ±0.01°) through a laser rangefinder or inclination sensor, and an alarm is triggered when it exceeds a safety threshold (such as 1/250).

Structural health assessment: Combine historical data and AI algorithms to predict the settlement risk of old buildings (such as brick-concrete structures over 20 years old) and guide reinforcement projects.

Case: In response to frequent strong winds and earthquakes, Hong Kong requires buildings over 10 stories high to install building tilt monitoring systems, which can reduce the collapse rate by 90%.

2.Economic Benefits: Reducing Disaster Losses and Maintenance Costs
Landslide prevention and control: Early warning can avoid secondary disasters such as road damage and power outages. It is estimated that each successful warning of a medium-sized landslide can save about 30%-50% of economic losses.

Optimize building maintenance: Detect hidden dangers (such as foundation settlement and concrete cracks) through regular monitoring to avoid huge compensation caused by sudden collapse.

Insurance and risk assessment innovation
Dynamic premium pricing: Insurance companies can provide “on-demand insurance” for high-risk areas (such as landslide zones) based on monitoring data, thereby reducing premiums or increasing underwriting willingness.
Engineering risk assessment: When building railways and roads in mountainous areas, the system provides real-time geological stability data, reducing survey costs by more than 30%.

3. Social Benefits: Improving the Level of Public Security Governance
Emergency resource dispatch: When a landslide occurs, the system automatically marks the dangerous area and plans a rescue route (for example, Chongqing's flash flood monitoring system is linked to firefighting drones, which improves rescue efficiency by 40%).

People's Livelihood Security and Fairness
Protection of vulnerable groups: Focus on monitoring mountain settlements and old communities to ensure the housing safety of low-income groups.

Information transparent: Disaster risk alerts are pushed to the public through map apps to enhance social disaster prevention awareness.

4.Technological promote: promoting the integrated development of multiple fields
Interdisciplinary technological innovation
Locally process video stream data and reduce latency to milliseconds to meet real-time warning needs.

Integrated air-ground-space monitoring: UAV cruise (centimeter-level resolution) + satellite remote sensing (wide-area coverage) + ground sensors (high precision) form a three-dimensional monitoring network.

Smart City Collaboration
Access to the city brain: Share data with meteorological, transportation, fire and other departments to build a unified command platform.

Digital twin applications: Establish a virtual model of the landslide area or building complex to simulate the disaster process and optimize emergency response plans.
