Is there a WiFi camera with an app for viewing when away from home, that has decent privacy? Plug and play would be nice. Limited time to do major setup as in 2 hours tops. Cost is fine nothing into 4 digits. Recording not neccesary. No storage is needed. Simple live viewing is all.
When you say “app” do you mean something that will let you view remotely through a residential NAT connection with no port forwarding or hole punching? Because 99.9% of those options are inherently not private.
If you only need the camera itself to have a local feed i.e. you already have some kind of VPN/tunnel/etc. into your home network, then something like a cheap Amcrest works fine and does not require Internet access for the camera itself.
Out of town viewing through tailscale or something similar. The feed needs to remain private from the LAN/WIFI. Only access is through me from outside the network.
