# Where should data analysis run?

Compare edge, local server and cloud processing through latency, uplink capacity and offline behavior. See how to test a split deployment on a real site.

The same workflow can run beside a camera, on a site server or in the cloud. The choice depends on response time, what data may leave the site and how the system should behave without a connection.

## Processing beside the source

Local processing can support a quick response over a limited uplink, with only selected events leaving the premises. Test the real stream resolution, memory use, sustained temperature and recording alongside analytics. A short run may conceal overheating or a growing queue.

## A server at the site

A local server can pool compute across multiple sources. Test simultaneous events from different cameras, internal network capacity and recovery after a restart. Decide which functions must remain available while the server is down.

## Cloud and split processing

Selected clips can go to the cloud for heavier analysis. Time to an answer then includes transfer and queueing. One arrangement detects an event on the device and forwards a short clip for interpretation. During an outage, define a limit for the queue and a retention period for pending evidence.

## Measure before choosing

Run the same recordings through each candidate layout. Measure time to the operator’s screen, transmitted data and behavior when the network is disconnected. The test shows which part of the workflow needs to stay on site.
