Edge Perception: Why We Don't Send Sensor Data to the Cloud

Streaming raw sensor data to the cloud for inference is the easy architecture — but for a safety response, a network round trip isn't a response time, it's a liability.

The Default Architecture Isn't the Right One Here

Most computer vision products stream raw frames to the cloud, run inference on a GPU cluster, and stream a result back. That architecture is easy to build and easy to scale — for a recommendation feed. For a safety response on a moving platform, a round trip to a data center is not a response time, it's a liability.

Three Decisions Made at Once

Running inference on-device — on microcontroller- and NPU-class hardware sitting next to the sensor — isn't just a latency decision. It's also a power decision (no radio constantly streaming frames) and, increasingly, a privacy and data-sovereignty decision: raw sensor data covering a factory floor or a hospital room never leaves the room it was captured in.

What This Costs, and What It Buys

Edge-constrained inference means real engineering tradeoffs — smaller models, tighter memory budgets, careful quantization. What it buys back is a system that keeps working when the network doesn't, and a security posture that doesn't depend on trusting every hop between a camera and a data center.

Built for the Hardware You Actually Have

We design perception for the hardware ranges our clients actually run — PLC-class controllers up through embedded NPUs — not for a GPU box we'd have to convince them to buy.
