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.
It always seems simplest to do this stuff with raspberry pi cameras or cheap webcams, and wired networks if feasible. Then use ffmpeg and icecast to stream through a VPS. Anything made as a consumer product is likely a shambles of crap software and security holes.
