I have cameras that do record. But parents do NOT have access. It's for cover my hiney only
They connect to an app on my ipad so I can monitor them. I set it up on a kick stand so that I can watch them all napping in the playroom while I fold laundry in my room or use the restroom.
They cost about $90 each, and I put a 128G SD card in each camera. They have a pretty wide angled lense so I only need 2 to cover where the kids hang out.
I don't think this should be mandated though. It's NOT mandated where we are, in California. I do this to cover my butt in case of an accusation. But this is my home...and those things can be hacked.
