If you're evaluating video analytics for a workplace — safety monitoring, security, or operations — one early decision shapes nearly everything that follows: where does the processing happen? On-premise (on hardware you own, at the edge) or in a vendor's cloud? This is a neutral primer on the trade-offs, so you can match the approach to your site rather than to a vendor's default.
Bandwidth and cost
Continuous video is heavy data. Sending many camera streams to the cloud for analysis means sustained upload bandwidth, plus storage and egress fees that scale with camera count and retention. On-premise processing keeps the video local and sends only lightweight results — events, snapshots, short clips — so ongoing data costs are far lower. The trade-off is up-front hardware and maintenance on site.
Latency
A round trip to a cloud region and back adds delay to every detection. For after-the-fact analytics that's irrelevant; for anything that needs to act in the moment — a proximity warning, a real-time alert — edge processing keeps the loop tight because inference happens on the same network as the cameras.
Privacy and compliance
Workplace camera footage is sensitive personal data. Routing it to a third party raises questions you then own: where is it stored, who can access it, how long is it retained, and does that satisfy your regulator, your works council and your customers' audits? Regimes such as the GDPR treat identifiable video as personal data with real obligations. Keeping footage on your own network removes many of these questions by design — the frames never leave the building — which is often the deciding factor in regulated or unionized environments.
Reliability
Edge systems keep working through an internet outage; cloud systems don't. Conversely, cloud platforms handle scaling, updates and backups for you. Which matters more depends on your connectivity and your IT capacity.
The simplest answer to "where does our camera footage go?" is "nowhere — it stays on our network." Whether you need that answer depends on your risk and your regulator.
A hybrid middle ground
It isn't strictly either/or. A common pattern is to process frames on-premise and sync only the results — alerts and metadata — to a central cloud dashboard. You get multi-site visibility without streaming raw video off-site, capturing much of the cloud's convenience while limiting the privacy and bandwidth exposure.
How to decide
- Do live detections need to drive action in seconds? Favor edge.
- Is camera footage subject to strict privacy rules? Favor on-premise or hybrid.
- Many sites needing one view, with limited on-site IT? A cloud or hybrid rollup helps.
- Unreliable connectivity? Edge keeps running regardless.
There's no universally right answer — only the one that fits your latency needs, privacy obligations and operational reality.
