I personally use Frigate, which is default free, but has a plus tier for $50 a year (has custom AI training/models instead of default’s standard model).
Personally has all the features I’d want, curious what BlueIris brings, I’ve heard a bit about it.
Power company engineer here, it’s true that a lot of our supporting and analytics software went down during the AWS event.
However, most devices that actually control grid units (called bulk electric system cyber-assets) are air-gapped or utilize a data diode.
FERC Reliability Standards and NERC CIP
However-er, flipping through those standards just now, turns out it’s 100% permitted to connect your “bulk electric system cyber-asset” to a cloud integration if done compliantly.
