I have some crap I found on amazon. https://www.amazon.com/dp/B07FFTQ8VR/ref=cm_sw_r_cp_apa_fabc_MZDVQ9HJZ23GQ2VFXR49?_encoding=UTF8&psc=1

They are out of stock but you might be able to find them from somewhere else. I bought them for a steal at $20 each. They are decent resolution, good ir distance, not so great at night with the ghosting of movement.

They are built with some godawful firmware that came with weird static IPs that I had to figure out over the course of hours.

I do have two lorax flir branded ball cameras that are very good. I only have one in right now at the front door. It is tack sharp and very good at night.
