When should intelligence be pushed to smart sensors versus keeping it in the cloud?
Push intelligence to the edge when latency is critical (like in safety shutdowns) or when connectivity is unreliable and expensive. Keep intelligence in the cloud when the detection logic needs frequent updates based on global data patterns, or when you lack embedded engineering resources to maintain and secure the edge code. The boundary is clear: if the decision rule is stable and local, put it on the sensor; if it's evolving and comparative, keep it in the cloud.
