Though Anker is a chinese company. Definitely review the privacy policy and such.
Arlo has a solid stance on privacy but is definitely cloud based unless you get one of the older ones with a base station. Their products are also made in china though.
You could also do the whole Raspberry Pi Cam thing.
The raspberry thing is not stable though on three pi zero w. I tried both motioneye and RPOS (the latter does rtsp and ONVIF) but the software hung really frequently and needed to be reset. I think you just need faster hardware.
