I’ll be a dad in a couple of months, and I bought Tapo C210 camera to use as a baby monitor. After couple of weeks of testing it works great, there is an integration to HA:

You can get an rstp stream from the camera and with go2rtc add-on you get live picture, it is pretty cheap (about $50) and has motion and baby crying detection, two way audio and works with HA localy.
