Wyzecam (bought two for €56 shipping included, amazon dot com)
I use them for babysitting, they have motion/sound detection and night vision. Happy with them.
You can connect them with ifttt to homey if you want, to trigger fows etc, although I don’t.
There are some outdoor enclosures available.
As a sidenote, there are variants of this device on the german market and the chinese.
