Rockfall & Change Detection

IRIS maps every rockfall, debris movement, and surface change, then links each detection to the original imagery.

  • Before/after evidence for every detected change
  • Highlighted regions show exactly where change occurred
  • Downloadable evidence packages for reporting

How IRIS Works

1

Connect

Add your cameras or cloud storage. Preview feeds instantly. Works with webcams, IP cameras, and remote archives.

2

Analyze

AI aligns each image and balances lighting automatically. Every new frame is compared against calibrated baselines.

3

Validate

Confidence scoring separates real changes from noise. Optional human review for critical alerts.

4

Alert

Get notified via dashboard, email, or API. Evidence packages ready for immediate reporting.

PhotoMonitoring Capabilities

One platform for landslide monitoring, rockfall detection, slope surveillance, and early warning.

Real-Time Awareness

Get notified minutes after imagery lands. Monitor multiple sites without added staff.

Visual Evidence Packages

Before/after viewer with downloadable proof for reports. Maps directly to areas of concern.

Complete History & Audits

Full time-series with trend reporting. Searchable audit trail for every event.

Multi-Interval Confidence

Short and long baseline comparisons with confidence scoring. Automatic escalation for critical findings.

GSD Calculator

Free GSD calculator for Ground Sample Distance, Field of View, and focal length. Plan your camera setup before deployment.

Pixel-Accurate Alignment

Stabilizes every frame for fair comparison. Balances lighting automatically so subtle changes stand out.

Managed Operations

Custom regions and schedules per site. Health checks, auto-resume, and team notifications.

Frequently Asked Questions

Common questions about camera-based monitoring, deployment, and how IRIS fits into your geotechnical monitoring workflows.

IRIS ingests RTSP, HLS, MJPEG, HTTP snapshots, webcams, time-lapse DSLRs, and secure SFTP/HTTPS archives. It handles high-resolution surveys without special hardware changes, enabling flexible camera-based landslide monitoring, rockfall detection, and slope surveillance with existing infrastructure.

Most teams connect existing cameras or archives in minutes. When you need field hardware, NHAZCA can survey, install, and calibrate turnkey systems, ensuring that geotechnical monitoring and early warning is fully integrated into your slope surveillance strategy.

IRIS aligns every frame, normalizes lighting, and uses multi-interval comparisons with confidence scoring to surface true change events instead of noise.

Alerts carry before/after imagery, highlighted change maps, and evidence packages that can feed dashboards, exports, and downstream notification systems for geotechnical monitoring and early warning workflows.

Yes. You can point IRIS to stored imagery on secure SFTP/HTTPS locations and run batch comparisons to build the same change maps used in realtime monitoring. This helps extract value from years of data and provides a consistent view of change over time.

Inclinometers and extensometers measure deformation at individual points. IRIS provides continuous visual coverage of entire slopes in a single view, detecting rockfalls, surface changes, and movement patterns that point sensors can miss. IRIS works alongside traditional geotechnical instrumentation, adding broad spatial coverage and higher measurement frequency without replacing precise point measurements.

Yes. IRIS runs M3C2 point cloud comparison entirely in the cloud. Upload two point clouds, and IRIS calculates distances, clusters changes, and computes volumes on our servers. View and explore results in a browser-based 3D viewer. No local software, no license, no GPU required.

It depends on the target. For rockfall monitoring, a GSD of 5–10 mm/pixel captures individual blocks. For broader slope deformation, 20–50 mm/pixel is often sufficient. Use our free GSD calculator to plan the right camera setup for your site distance and resolution requirements.
