Industrial edge vision, no cloud

Architecture edge pour la vision par ordinateur : décision locale et latence minimale.

In short: edge computing is becoming the default path for production vision deployments. Local decisions, streams that stay on site, simpler GDPR / AI Act posture. The right platform is not the most powerful, but the one that meets your latency, power, temperature and lifecycle constraints.

1) Why edge in 2026

Field use cases (quality control, PPE compliance) need millisecond decisions, offline robustness and stricter data governance. Edge cuts latency, reduces cloud cost and keeps sensitive streams on site - a decisive advantage versus full-cloud architectures.

2) Les critères qui comptent vraiment

Latence end‑to‑end : capteur → inférence → action. C’est le vrai KPI opérationnel.

Budget thermique & énergie : indispensable pour les armoires compactes et les environnements difficiles.

Cycle de vie hardware : disponibilité multi‑années, pièces remplaçables, maintenance simple.

Coût total : hardware + intégration + supervision + maintenance.

3) Comparing platform families

In practice, three families dominate: dedicated embedded systems, compact edge servers, and hybrid architectures (specialized accelerators + CPU). The choice mostly depends on real-time criticality and the number of video streams.

To choose the right compute unit, start from the operational need (target FPS, resolution, number of streams) rather than a single headline number. INT8 TOPS are a useful proxy, but they don’t “guarantee” real performance: it depends on the model (YOLO / segmentation / tracking), precision (INT8/FP16), pre/post-processing, and total sensor → decision latency.

A simple rule: size your model first (size, batch, frequency) and keep margin for peaks and future changes (new use cases, denser scenes). Also check memory (some pipelines hit RAM/VRAM limits before TOPS), thermal budget (throttling), and long-life availability (maintenance, replacements). In short: pick the Jetson that sustains your full pipeline, not just inference.
