Non-Contact Monitoring for Existing Buildings and Urban Structures

Haytham’s solution uses the Online Visual Tracking System, passive targets, data transmission, and a cloud platform for continuous monitoring of existing buildings and surrounding structures.

Building Tilt · Differential Settlement · Structural Deflection · Crack Opening · Curtain Wall Displacement

Non-Contact Visual Monitoring

Using oblique optical-axis imaging and sub-pixel tracking, the system remotely measures 2D displacement at multiple points on façades, beams, slabs, curtain walls, and other critical locations.

Key Features

▪Remote Non-Contact Monitoring

No direct contact with the structure

▪Multi-Point Measurement

One system monitors multiple points simultaneously

▪Sub-Millimeter Accuracy

High-precision displacement measurement under suitable conditions

▪Continuous Monitoring

Suitable for long-term unattended operation

▪Automatic Alerts

Multi-level alerts for abnormal deformation

▪Sensor Integration

Supports settlement, tilt, strain, vibration, and crack sensors

Monitoring System

Visual Sensing → Data Transmission → Cloud Platform → Early Warning

Supports 4G/5G and Ethernet, with real-time dashboards, historical trends, report export, and API integration.

Applications

▪Existing & Aging Buildings
Monitor long-term tilt, settlement, and structural deformation.

▪Damaged or High-Risk Buildings
Remote monitoring without entering hazardous areas.

▪Construction Impact Monitoring
Track settlement, tilt, and cracking caused by nearby excavation, tunneling, or piling.

▪Historic Buildings
Low-disturbance monitoring with reversible target installation.

▪Curtain Wall Monitoring
Monitor displacement and deformation of curtain walls and façade components.

▪Large-Span Buildings
Deflection and deformation monitoring for stadiums, exhibition centers, stations, and large roofs.
