# SightRadar Blog — Face Recognition Engineering

> Build guides, comparisons, and concepts for engineers building face recognition: migrating off AWS Rekognition, selfie search, event photo tagging, face verification, multi-tenant architecture, thresholds, cost, and more.

The SightRadar blog is a hub of practical, engineering-focused articles on building face recognition into real products. Every article is also available as a clean Markdown twin at `/blog/<slug>/llms.txt` for LLM/assistant citation.

## Topics covered

- **Guides** — migrate IndexFaces/SearchFacesByImage from AWS Rekognition, build selfie-based face search, event & wedding photo face-tagging, add 1:1 face verification to signup, multi-tenant face-search architecture, detect duplicate accounts by face, HEIC/WebP image ingestion, build a face-recognition photo-sharing platform.
- **Cost** — how much a face recognition API costs (worked scenarios vs Rekognition), self-hosted vs hosted TCO, scaling an event photo platform (worked economics model).
- **Concepts** — what a faceprint/embedding is, choosing a face-match threshold (FMR/FNMR).
- **Learn** — face recognition project ideas for students, a Python beginners' tutorial, building an attendance system as a student project.
