Data handling & security.

A technical description of what data QueueFlow Sentinel processes, stores, and explicitly excludes.

Data scope

What is processed.

Data Sentinel processes
  • Event timestamps (ISO 8601)
  • Event type identifiers (motion, doorbell, etc.)
  • Device identifiers (camera/device ID strings)
  • Location tags assigned by the operator
  • Event frequency aggregates
  • Dwell interval calculations
Data never accessed
  • Video frames or recorded video
  • Live video streams
  • Audio content of any kind
  • Facial recognition data
  • Biometric identifiers
  • Individual identity information
  • Physical location of persons
Architecture

How the system is built.

Read-only integration

The integration model is strictly read-only. QueueFlow Sentinel does not issue commands, modify device configuration, or interact with device control APIs.

Deterministic evaluation

All alert decisions are produced by a rule-based engine with explicit thresholds. No machine learning models are used in the decision path. Identical inputs produce identical outputs.

Immutable audit trail

Every decision — allow or suppress — is written to an append-only log with full input state and rule match data. Records cannot be modified or deleted.

Serverless infrastructure

Deployed on AWS Lambda with event-driven architecture. No persistent compute instances. Data processed in isolated execution environments per event.

Encrypted at rest & transit

All stored metadata is encrypted at rest (AES-256). All data in transit uses TLS 1.2 minimum. No plaintext transmission at any layer.

Retention policy

Event metadata and audit records are retained for 90 days by default. Enterprise customers may configure custom retention windows within contractual limits.
