What do we measure?

3D displacement between two tags.

From video to 3D displacement data.

Our software reconstructs the measurement point in 3D and compares it with previous captures. Then it extracts displacement data for you.

Metal tags made for any structure, any environment.

Attach the tags on both sides of a crack, joint, bearing, or any other element you want to measure.

The tags create a stable reference for accurate measurements with smartphones, cameras, or drones. Their anodized and engraved surface is made to resist UV light, chemicals, pressure washing, and long-term outdoor use.

For engineers

Smarter monitoring. Less work.

01

Let anyone collect the data

Clients and inspectors can take measurements with their own phones. Every capture is checked automatically before processing.

02

Install in minutes

Glue the tags in place and start monitoring. No cables, power supply, or recalibration between visits.

03

Use the camera you already have

Capture measurements with a smartphone or drone. No specialist equipment required.

04

See movement in context

View every measurement point and its displacement directly on the 3D model of the structure.

Let clients, inspectors, or on-site teams collect measurements without a full platform account. Each measurement is checked for quality before being added, so you can collect reliable data without going on site.
Temperature correlationProfessionalEnterprise
Automatically retrieve temperature data and compare it with movement data to help distinguish thermal effects from structural changes.
Personalised reportsProfessionalEnterprise
Generate engineering reports for all your projects with one click. Configure the analysis trends and correlations you want to see and get a deeper analysis, produced automatically from your structure's data.
White label / brandingEnterprise
Create reports and client-facing outputs with your own branding.
Dedicated support and procurementEnterprise
Receive dedicated support for onboarding, deployment, procurement and integration into your organization's workflow.
Drone measurementsEnterprise
Capture measurements at difficult-to-access monitoring points using drone footage.
