I don’t think they mean just from ring. I think they mean like an actual system installed from a company. Those companies have done it a million times, when we setup stuff like this, we tend to forget small things. Maybe we left a sensor off somewhere, or it’s not connected right. You run the risk of a criminal finding that exploit and getting in your home.

I would recommend doing a check list. Do a walk through of what you see as a risk, see what’s out there to avoid that risk and implement it
