Enter #homeassistant. I do not want to tell #v380 app my home wifi password, so I need some other cam.
For a while, #esp32cam was fine. Caveat: I never had a suitable ethernet shield when I needed it, so I ended up putting #esp8266 as wifi repeaters all over the house (well, mainly the basement and other remote places).

I don't remember why but I own a cheap wifi cam from 2018/2019 which actually works pretty well compared to anything low-priced I recently encountered... It has nightvision and I can set it up with the #v380 app. I configure it to create its own access point and can take a look at an #rtsp stream with "Cams" app https://f-droid.org/en/packages/com.vladpen.cams/.
