Tap or span off the switch into a packet analyzer like silk… you only really need the header info. Take a sample of the traffic the camera will be pushing… ports amount of data destination MAC/IP.

Find a SOAR or automation platform that works for you. Set it up to search the SPAN/TAP data off the switch in the analyzer… and the moment that camera starts sending something that ISN’T baseline traffic… shut the port down on the switch and send you an email about it.

I didn’t have luck with power loss in certain areas.

Spectrum at my last house would go out during widespread power loss. It doesn’t go out at my current house during widespread power loss… At least not on the short term.

I have starlink as a backup in the event spectrum goes out.
