Coastal sensing
Distributed shoreline cameras, environmental sensor nodes, wave and tide inputs, weather and water-condition feeds, and responder locations create the physical picture of the site.
ShoreSense
Menu
From shoreline sensing to coordinated response.
ShoreSense connects physical sensing hardware with edge computer vision, environmental forecasting, a littoral digital twin, and human-reviewed rescue coordination in a fully built integrated prototype.
Hardware designed around the shoreline, not one equipment vendor.
The sensing layer combines visual, environmental, and operational inputs. The CAD studies show how components are organized, connected, and accessed for service.
Camera + edge
The camera, adjustable bracket and local-compute enclosure form a serviceable shoreline unit.

Beach-side computing
A local edge gateway synchronizes observations and runs safety-relevant visual analysis close to the source. Event metadata can move upstream without continuously transmitting full video.
Connected operations
The same architecture can incorporate existing public data feeds, beach-specific sensor networks, and the positions of lifeguards, rescue boards, watercraft, and other response assets.
Evidence before action.
The review workflow brings source media, shoreline cells, forecasts and response options into one workspace. This interactive design preview uses a reference image and a separate synthetic scenario.

Patent-pending architecture.
U.S. Patent Application No. 64/117,500 covers the integrated system architecture, including multimodal sensing, adaptive shoreline cells, temporal risk modeling, and rescue-resource orchestration.
A living model of the shoreline.
The littoral digital twin represents the coast as adaptive georeferenced cells. Tracked people, sensor nodes, hazards, and rescue assets become connected parts of one changing model.
- Hydrodynamic relationships
- How conditions can move between neighboring shoreline cells.
- Visibility relationships
- What each camera and observer can reliably see.
- Human-motion relationships
- How tracked people are moving through the surf zone.
- Travel-time relationships
- How quickly rescue assets can reach changing areas of risk.
The complete response loop.
The system is built to preserve context as data moves from the coast to a decision. Each stage adds a different form of understanding.
Coastal environment
People, waves, tides, weather, water conditions, and rescue coverage
Sensing hardware
Distributed cameras, environmental nodes, connected coastal feeds, and responder locations
Edge intelligence
Person detection, tracking, optical flow, hazard segmentation, and privacy-aware local processing
Littoral digital twin
Adaptive shoreline cells connect people, sensors, hazards, and rescue assets
Prediction
Localized risk and uncertainty are estimated now and across 5, 15, and 30 minute horizons
Coordination
Warnings, patrol positioning, rescue staging, routing, and human-reviewed decisions
Computer vision follows motion over time.
Potential distress cannot be understood from a single frame. ShoreSense links detections across time, analyzes movement, and evaluates them alongside changing water conditions.
Video
Camera streams enter the local processing gateway.
People
Detection and multi-object tracking maintain continuous swimmer trajectories.
Movement
Pose, direction, offshore drift, submergence, and purposeful motion are analyzed over time.
Water
Optical flow and segmentation estimate hazardous current structure and surf-zone change.
Context
Visual outputs are fused with tide, waves, shoreline geometry, visibility, and uncertainty.
Risk is mapped across place and time.
Every update produces localized estimates instead of one beach-wide label. The forecasting layer projects how conditions may evolve and keeps uncertainty visible to the operator.

From observation to response.
The intended workflow follows one continuous sequence, with a person reviewing consequential decisions.
Data enters the system.
Camera streams, environmental observations, public coastal feeds, and responder locations are synchronized and georeferenced.
People and conditions are detected.
Edge models track swimmers, analyze temporal behavior, estimate optical flow, and identify changing hazard structure.
The digital twin updates.
Localized cells connect physical conditions with people, sensors, visibility, rescue coverage, and uncertainty.
Risk is forecast.
The fusion layer estimates how hazards and exposure may evolve across immediate and future horizons.
Response options are prioritized.
ShoreSense recommends warnings, patrol positioning, rescue staging, and asset routing for trained human review.
