Data Infrastructure
From observer capture to structured delivery, every step of the Sentinel Watch data pipeline is designed for integrity, traceability, and direct integration with enterprise ML and analytics stacks.
The Observer Network
The Sentinel Watch observer network is the data collection layer. It is geographically distributed, protocol-driven, and deployed specifically for each client program. Observers operate across a range of environments — retail, public spaces, commercial facilities, outdoor locations — using a structured reporting application purpose-built for field observation tasks.
Structured Capture
Observers do not submit free-text descriptions. Every observation is captured through a structured form built from your taxonomy — predefined event types, classification fields, and required metadata. This enforces consistency at the point of capture rather than requiring cleanup downstream.
Timestamp & Geolocation at Source
Every observation is timestamped and geolocated at the moment of capture — not at submission. This is critical for programs where temporal or geographic precision matters. Network delays do not distort event metadata.
Offline Resilience
The observer application uses a progressive web app architecture with offline-first design. Observations captured in low-connectivity environments are queued locally and synced automatically when connection is restored. Field coverage is not limited by network infrastructure.
The Data Pipeline
Raw submissions from observers pass through a defined pipeline before reaching your dataset. Each stage adds structure, removes noise, and prepares the data for direct use.
- Capture — Observer submits a structured observation via the field reporting app. Timestamp, geolocation, and classification fields are recorded at the point of capture.
- Validation — Submissions are automatically checked for completeness and schema compliance. Incomplete or malformed records are flagged for observer follow-up before they enter the review queue.
- Review — A human review layer assesses ambiguous classifications, edge cases, and outliers against your taxonomy. Adjudicated records are either confirmed, corrected, or rejected.
- Structuring — Confirmed observations are formatted according to your specified output schema — JSON, CSV, or a custom format for direct pipeline ingestion.
- Delivery — Data is delivered to your endpoint on the agreed schedule — batch, incremental, or via the Sentinel Watch MCP API for real-time access.
Output Formats & Integration
Structured JSON / CSV
Standard delivery format for batch programs. Each observation record contains your taxonomy fields, event metadata, timestamp, geolocation, observer identifier, and quality review status. Ready for direct ingestion into data warehouses, labeling platforms, or ML training pipelines.
MCP API Access
Enterprise clients with MCP integration can query their observation data programmatically via their dedicated connection at app.sentinel-watch.org. AI agents and automation pipelines can retrieve, filter, and act on observation data without manual data transfers.
Custom Schema
For clients with specific downstream requirements — proprietary labeling formats, database schemas, or platform-specific data structures — output can be customized to match your existing pipeline without transformation work on your end.
Platform Infrastructure
Sentinel Watch runs on Google Cloud infrastructure with autoscaling compute, global data center coverage, and high-availability architecture. The platform supports programs across multiple time zones and geographies without performance degradation as observation volume grows.
The enterprise client portal and MCP server are hosted at app.sentinel-watch.org, isolated from the observer-facing infrastructure. Client access, program management, and data retrieval operate on dedicated, scoped connections that do not share resources with other client environments.
