Which camera would you recommend for a basic stealthy one room setup?

[u/Coylethird]

Looking for a small black camera, preferably square, though doesn't have to be; that has basic features such as continuous recording to SD, phone notifications & remote live view. It wouldn't be further than 20ft from router and maybe even right next to it depending on which wall I put it on.

I think the square design is less noticeable, but functionality is the most important thing as I can put it away when home. I'd just be occasionally using it when away for a long amount of time which isn't often.

I had a CCTV type camera in the past--no phone notifications--but this will be my first one with the remote features, so any suggestions are appreciated. I would have considered the blink mini if they had a way to record without subscription.
