So my wife installed Ring camera in the living room to monitor screen time

I am NOT okay with this. Yes, our 9 and 12 year old spend too much time gaming, but a hidden camera to spy on them? I said this crosses a line but apparently I'm not "concerned enough" about the problem. This feels like a trust issue more than a tech issue. Am I wrong to be this upset about it? How do you guys handle monitoring without feeling like a Big Brother?
