Gonna throw in another Reolink recommendation. I use Blue Iris as my NVR and have both that and the Reolink integrations in Home Assistant for motion notifications and lighting control. The cameras are durable (even in my very cold temps like -30C) and have really good image quality. If you don't have an NVR or Home Assistant, the built-in motion detection and app is still pretty good and you can just pop an SD card in for recording.
