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.
