Never use cameras than rely on some dubious (or even on legit) cloud “providers”. Heck knows that employees do with the content. I bought a baby monitor off of amazon once only to discover it sends content somewhere in china. Never again. Went for a local radio based monitor and called it a day. Ring doorbells have their camera off when at home. Also they are pointed towards objects (door or parked car).
Yup, my setup is local RTSP cameras with firewall rules to completely block traffic to/from them, local Frigate server that pulls the stream and runs object recognition and handles recording, and then a Wireguard VPN if I need access from outside the local network.
It's been very reliable, has no fees, and I'm not worried about cameras being hacked or cloud storage issues.
