Site-level response
Keep selected analysis near the cameras when the decision needs to happen close to the physical environment.
Edge processing
Evaluate local processing when the workflow benefits from site-level inference, controlled data movement, or resilient connectivity.

Keep selected analysis near the cameras when the decision needs to happen close to the physical environment.
Consider processing selected signals locally instead of moving every raw stream elsewhere.
Design for the reality of intermittent connectivity, local dependencies, and recovery procedures.
Use an appropriate management layer to monitor and update distributed deployments.
Edge planning
A measured choice
Edge processing can help with latency, resilience, or bandwidth, but it introduces a distributed fleet that still needs inventory, patching, credentials, observability, and a replacement plan.
The proof of concept should test both the model and the operating burden.
