What are you all doing for offline notifications?

[adamzeis]

Just curious what you all are doing for offline notifications when your cameras go down as it's not something that's built into the app. I have a few cameras outside that go offline from time to time, but I won't notice until days later at some points. I have all my cameras in HASS now, but I don't really see an entity just for status or something that I can use as a trigger when they go offline. Maybe I'm just being daft and totally missing something obvious though. Any ideas?
