A second vote for Reolink. They’re entirely adequate for most home scenarios.

Dahua are also very good if you can find them however they are aimed at professional installers. They cover almost every scenario imaginable and have good on device ai features. They do have their idiosyncrasies but do everything you could need and offer excellent lowlight performance for very little cost. There is also a very good home assistant integration.

You’ll find a lot of people tend to chose between Dahua and the more expensive Hikvision on cctvforums. You should be able to pick up a capable 4mp Dahua with tripwire detection for 60GBP. These cameras can (sometimes literally) see in the dark.

Avoid ESP32 Cams. They are very low frame rate and produce a very noisy image. They’re fun to tinker with but are nowhere near the quality of a real IPC.
