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.
As far as easy, commercially available stuff I like UniFi. You can set custom recording schedules, or never record. Or only record motion. You can also set privacy zones which are blacked out and not visible or recorded.
You do need one of their consoles or NVRs to manage them though, and they aren’t super cheap.
